    Oxidation and dissolution of tungsten carbide powder in water2000In: Int J Refract Met Hard Mater, ISSN 0263-4368, Vol. 18, p. 35-43Article in journal (Refereed)
    Abstract [en]

    The oxidation and dissolution of tungsten carbide powder dispersed in water was investigated using XPS and leaching studies. We found that the WO3 surface layer on the oxidised tungsten carbide powder dissolves readily at pH>3 with the tungsten concentration increasing linearly with time. Adding cobalt powder to the tungsten carbide suspension resulted in a significant reduction of the dissolution rate at pH<10, when the concentration of dissolved Co is high in the solution phase. Electrokinetic studies indicate that the reduced dissolution rate may be related to the formation of surface complexes; experiments showed that Co species in solution adsorb on the oxidised tungsten carbide powder. The experimental data were discussed in relation to theoretical modelling of the WO3 solution chemistry and the Co2+ adsorption at oxide/water interfaces

    Krypgrundssystem för moderna småhus utvecklingsmöjligheter1987Report (Other academic)
    Abstract [sv]

    Högre isolerstandard och ökade täthetskrav ökar risken för skador i kryprum. Ny teknik behövs, oftast kan åtgärderna vara enkla. System för kryprumsgrundläggning har studerats förutsättningslöst för att föreslå förbättringar som ökar säkerheten mot fuktskador. Kalla och varma krypgrunder har studerats i litteratur, vid besök, i kontakt med experter i Sverige och utomlands samt vid beräkningar och försök. Idéer till åtgärder, såsom modifieringar av material, konstruktion, ventilation samt till konstruktionslösningar och forskningsuppgifter, ges.

    Putsning av möbelkomponenter med hjälp av industrirobot1990Report (Other academic)
    Abstract [sv]

    Gjorda försök visar att industrirobotar kan utnyttjas för finputsning av träkomponenter. Det är dock nödvändigt att detaljerna tillverkas så att form och mått kan förutsägas inom givna toleranser. I många fall kan detta krav uppfyllas genom CNC-bearbetning. Mindre detaljer kan med fördel hållas av roboten, större laminerade detaljer bör spännas upp i fixturer. Rekommendationer om hur man bör gå till väga finns i rapporten.

    Montering av trämöbler med hjälp av industrirobot1992Report (Other academic)
    Abstract [sv]

    Försök med montering av trämöbler med industrirobot visar att de detaljer som skall monteras måste vara "formsäkra" inom givna måttoleranser för att monteringen skall bli säker. Gripning av detaljerna med vakuum fungerar mycket bra. De många momenten leder dock till många tidskrävande verktygsväxlingar.

    Packages for liquids - Internal Pressure Test2008Report (Refereed)
    Abstract [en]

    The basic requirements for transport of dangerous gods are that a packaging shall be able to withstand certain mechanical and chemical stresses, as stated in SRVFS 2006:7. The requirements shall guarantee a reasonable level of protection for both humans and environment and is intended to create a system taking into account different types of substances and packaging. Principles for classification, packing requirements, testing procedures shall be simple and clear and guarantee that a minimum level of safety can be achieved without advanced technical equipment and expertise. No requirements concerning test temperatures are given in the regulations but in the standard SS-EN-ISO 16104:2003 “Packaging – Transport packaging for dangerous goods – Test Methods” the internal hydraulic pressure test, for plastics drums, jerricans and composite packaging, shall be performed at a temperature of +12 °C, otherwise the internal test pressure shall be adjusted with a pressurization factor corresponding to the temperatures used in the test. At temperatures below +12 +/- 2 °C the test pressure is increased and if the temperature is higher the pressure is lowered. Correction factors exist from +2 °C to +20 °C, and for all temperatures above +20 °C the correction factor is the same as for +20 °C. Neither ADR, IMDG-code, ICAO-TI or the UN-recommendations recommend any test temperature. The aim with this project was to perform internal pressure test at different water temperatures. Three jerricans of each type were tested at the following temperatures: +3, +20, +40 and +55 °C. As can be seen in the test results the burst pressure decreases substantially with rising temperature. For jerrican A the burst pressure is reduced from 234 kPa at +3 °C to 175 kPa at +20 °C, 151 kPa at 40 °C and 114 kPa at +55 °C. At +55 °C the burst pressure is reduced to less than half what it was at +3 °C. Jerrican B is also reduced from 545 kPA at +3 °C to 226 kPa at +55 °C while jerrican C is only reduced from 185 kPa to 136 kPa in the same temperature interval. The gradient of the correction factor in table 3 in EN ISO 16104:2003 correspond very well with gradient of the tested jerricans in the temperature span between +2 °C and +20 °C. All jerricans were made of PE. The pressure/temperature curves show a linear gradient but indicates that the gradient can differ between different materials. Jerrican A and B are produced by the same manufacturer in the same material and show corresponding behaviour, also corresponding to the correction factors in the standard. Jerrican C is produced by another manufacturer and does not show such significant reduction of burst pressure at higher temperatures.

    Fönsterlyft2013Report (Refereed)
    Abstract [sv]

    Detta projekt syftar till vidareutveckling av en uppfinning som har potential att väsentligen förenkla och effektivisera ett arbetsmoment, att lyfta av och på utåtgående sidohängda fönster, som är ett välkänt arbetsmiljöproblem. Resultatet från undersökningen visar att verktyget har utvecklingsmöjligheter och att radikalt minskar de ergonomiska problemen och att användningen kan ge goda möjligheter att effektivisera arbetet. Verktyget måste betraktas som ett lyftredskap och omfattas av därför av ett regelverk som innebär att vissa kriterier måste uppfyllas. Undersökningar i detta projekt visar att verktyget uppfyller de formella krav som ställs på det. Undersökningen visar också att det fungerar på avsett sätt dvs för att lyfta ur och sätta tillbaka utåtgående sidohängda fönster. Verktyget har provats av branschfolk som varit positiva till lösningen men bedömt den som svår att använda beroende på att den består av för många delar och att det är en stor förändring jämför med dagens arbetssätt med två man i arbetslaget. Med hänsyn tagen till de synpunkter som kommit från branschfolk i detta projekt är ett naturligt nästa steg att förenkla och anpassa verktyget till ett tvåmansverktyg. Verktyget blir då mer lättanvänt för ett arbetslag på två personer. Tillverkningskostnaden blir dessutom lägre för det anpassade verktyget. Om den förenklade lösningen får ett genomslag på marknaden innebär detta att företaget kommer igång med försäljning och produktion. I ett senare skede kan företaget vidareutveckla och marknadsintroducera det enmans-verktyg som var ursprunget till detta projekt och som fortfarande bedöms vara den allra effektivaste lösningen för arbetsmomentet att lyfta av och på fönster.

    Från living labs till transition labs - En forskningsöversikt och kartläggning av innovationsmiljöer för hållbara städer2018Report (Other academic)
    Abstract [sv]

    Samhällen ställs i allt större grad inför komplexa utmaningar som blir allt svårare att hanteramed befintliga resurser och arbetssätt. För att kunna skapa förutsättningar för ett välmående,ekologiskt och socialt hållbart samhälle, nu och i framtiden, behöver en omfattande kursändringske. Behovet av sociala, organisatoriska och tekniska innovationer, som på olika sättbidrar till att ersätta ohållbara energi- och transportsystem samt föråldrade sätt att producerasamhällstjänster och kunskap på, är stort.Den samhällsvetenskapliga forskningen lyfter fram vikten av bred samverkan mellan sektorsochmyndighetsgränser för att kunna ta sig an komplexa hållbarhetsutmaningar. Dagensstuprörstänkande försvårar gemensam kunskapsproduktion och problemlösning. Däremotfinns det tecken på att den traditionella, hierarkiska och centralistiska samhällsstyrningenhåller på att omformas till att bli mer nätverksbaserad, horisontell och samarbetsbaserad.Denna styrningsform - som i den engelska litteraturen kallas för governance - bygger i högre gradpå nätverkande och flernivåsamverkan mellan näringsliv, offentlig sektor och civilsamhället.När det gäller hållbar utveckling och innovation anses städerna spela en allt viktigare roll. Delsär städer kraftfulla påverkansnoder som främjar spridningen av radikala innovationer; dels bidrarstädernas unika synergier och tillgång till infrastruktur, kapital och kompetenser till ökadinnovationsförmåga. Hur skall städerna organisera sig för att kunna öka samverkan och främja ettexperimentellt förhållningssätt för att kunna ta sig an komplexa utmaningar? Hur skallstäderna organisera sig för att dra nytta av den ökade innovationsförmågan givet desamhällsutmaningar vi står inför?I Sverige och internationellt har nya typer av organisationsformer och arenor börjar växa framsom ett svar på ovan tecknade utmaningar: urban living labs, urban transition labs, social labs, policy labs,innovationsplattform för att ta några exempel. Alla dessa miljöer har som syfte att främja flernivåsamverkan,innovation och problemlösning. I Sverige främjas denna utveckling främst tackvare innovationsmyndigeten Vinnova som på olika sätt stödjer dessa framväxande försök atthitta nya typer av organisationsformer. I Europa sker stora satsningar på liknande miljöergenom Horizon 2020 och JPI Urban Europe. Syftet med den här rapporten är att ge en bild avhur dessa nya innovationsmiljöer växer fram som styrverktyg för att driva hållbar stadsutveckling.I anslutning till rapporten har även gjorts en kartläggning och klassificering avsvenska innovationsmiljöer för hållbara städer.

    Toward an enzyme-based oxygen scavenging laminate.: Influence of industrial lamination conditions on the performance of glucose oxidase2002In: Biotechnology and Bioengineering, ISSN 0006-3592, E-ISSN 1097-0290, Vol. 79, no 1, p. 37-42Article in journal (Refereed)
    Abstract [en]

    The laminate consisted of several polymer layers, aluminium, and one cellulose-based layer containing the active enzymatic system (e.g., glucose oxidase, catalase, glucose, and CaCO3). During the industrial lamination process, the enzyme layer was exposed to three temperature spikes up to 325°C without significant enzyme inactivation. Ninety-seven percent of the glucose oxidase activity still remained after the lamination process. The best laminate had an oxygen absorbing capacity of 7.6 ± 1.0 L/m2. A reference that was not laminated expressed a corresponding oxygen absorbing capacity of 7.1 ± 0.8 L/m2. © 2002 Wiley Periodicals, Inc.

    Slag-metal reactions during ladle treatment with focus on desulphurisation2002In: Ironmaking & steelmaking, ISSN 0301-9233, E-ISSN 1743-2812, Vol. 29, no 3, p. 224-232Article in journal (Refereed)
    Abstract [en]

    Within several cooperative projects, KTH (Royal Institute of Technology), Ovako Steel AB, and MEFOS have investigated the desulphurisation of bearing steel during vacuum degassing. The work includes thermodynamic calculations of the slag-metal equilibrium, CFD modelling of slag-metal reactions, and plant trials. Results from the various studies are presented and discussed in this paper. Models for predicting slag properties (sulphide capacity, viscosity, and oxide activities) in liquid slags as functions of slag composition and temperature have been used for the calculation of data which have been employed in static and dynamic modelling of sulphur refining. The results from static modelling show that the method allows fast and easy evaluation of the theoretical desulphurisation conditions during degassing at Ovako Steel AB, as well as theoretical determination of the parameters that have the greatest influence on the equilibrium sulphur distribution. The conclusion from dynamic modelling is that the vacuum degassing operation can be described dynamically with the present knowledge of sulphide capacity, sulphur distribution, viscosity, and oxide activities of ladle slags if this knowledge is combined with fluid flow modelling to derive the overall kinetics. The presented model approaches have been found useful in understanding the sulphur refining process at Ovako Steel AB. The dynamic modelling concept is also believed to have potential for dynamic descriptions of other slag-metal reactions in steelmaking. © 2002 IoM Communications Ltd.

    Peer-to-peer service sharing platforms: Driving share and share alike on a mass-scale2013In: International Conference on Information Systems (ICIS 2013): Reshaping Society Through Information Systems Design, 2013, p. 2964-2978Conference paper (Refereed)
    Abstract [en]

    The sharing economy has been growing continuously in the last decade thanks to the proliferation of internet-based platforms that allow people to disintermediate the traditional commercial channels and to share excess resources and trade with one another effectively at a reasonably low transaction cost. Whereas early peer-to-peer platforms were designed to enable file sharing and goods trading, we recently witness the emergence of a new breed of peer-to-peer platforms that are designed for ordinary service sharing. Ordinary services entail intangible provisions and are defined as an economic activity that generates immaterial benefits and does not result in ownership of material goods. Based on a structured analysis of 41 internet-based rideshare platforms, we explore and layout the unique characteristics of peer-to-peer service sharing platforms based on three distinct temporal patterns that entail specific consequences for platform use as well as provide insights about their overall design imperative. © (2013) by the AIS/ICIS Administrative Office All rights reserved.

    Abstract [en]

    The emergence of ubiquitous computing offers new possibilities and opportunities for organizations attempting to improve their productivity and effectiveness. in particular, the promises of ubiquitous computing are attractive to organizations such as transport firms, in which coordination of diverse sets of mobile units is central to organizational performance. This article analyzes the use of ubiquitous transport systems in Swedish road haulage firms and discusses the opportunities and challenges for the early adopters. It pays specific attention to the mobile–stationary divide; that is, the set of challenges associated with integration of mobile and stationary people and systems into a seamless computing environment.

    Architectural knowledge in inter-organizational IT innovation2008In: Journal of strategic information systems, ISSN 0963-8687, E-ISSN 1873-1198, Vol. 17, no 1, p. 19-38Article in journal (Refereed)
    Abstract [en]

    This paper examines the front-end process of inter-organizational IT innovation. In particular, it focuses on the nature and role of architectural knowledge. Such knowledge is important for development of architectures capable of serving the goals of heterogeneous actors and technologies. Yet, surprisingly little research has been done on how architectural knowledge may be developed through collective achievements. This paper presents a theoretical model of architectural knowledge development in inter-organizational IT innovation. Applying this model throughout an action research project within the Swedish transport industry, the paper identifies four dimensions of architectural knowledge that proved important for facilitating an industry-wide ubiquitous computing environment. The four dimensions are technology capability awareness, use context sensitivity, business model understanding, and boundary-spanning competence. We conclude the paper by outlining the theoretical and strategy implications of the model and the four dimensions of architectural knowledge. © 2008 Elsevier B.V. All rights reserved.

    Mapping and Evaluation of some Restricted Chemical Substances in Recycled Plastics Originating from ELV and WEEE Collected in Europe2019Report (Other academic)
    Abstract [en]

    Recycling of plastics is a critical step toward the realisation of a sustainable society. Plastic is a fitting material to recycle, as it often can easily be melted and formed into new products. Plastic recycling is therefore an easy process with pure plastics, however, most of the plastics that are recycled today are not pure and contain additives and/or impurities. Some of these additives can be hazardous substances that could be harmful for both humans and the environment. It is therefore important that these hazardous substances are not recycled and transferred into new products. To ensure a safe use of plastics, these substances are today regulated in new products, but old products could still contain these substances (legacy chemicals). To comply with legislation it is therefore critical that these substances are removed during the recycling process. There are however many hazardous substances that are yet not regulated, which may also be present in products and therefore recycled material. 

    Waste Electronic and Electrical Equipment (WEEE) and End-of-Life Vehicles (ELV) are two of the materials streams that contains a high amount of legacy chemicals. These streams have been associated with spreading legacy chemicals after recycling. In several reports WEEE plastics have been identified as the source of brominated flame retardants (BRF) found in toys and everyday items. According to the EU regulation the use of certain BFRs is not permitted in new products or articles above a certain value. Recyclers and resellers of the recycled plastic often specified that the products should not be used in toys, medical equipment of food contact application, yet BFRs from WEEE can still be found in these products. This could mean that either producers that use recycled material in new products do not follow the recommendations from the recyclers, or that the recycled material does not fulfil the regulations. Another possibility for the findings of legacy chemicals in these items could be a meagre follow-up on imported plastics.

    In this study the Research Institutes of Sweden (RISE) has, on behalf of the Swedish Environmental Protection Agency (Naturvårdsverket), investigated the content of legacy chemicals in recycled plastics that have been processed in a recycling facility. The plastics originated from WEEE and ELV and have been gathered from recyclers across Europe. A number of different legacy chemicals were investigated, both inorganic (Cd, Pb, Hg) and organic substances (flame retardants and plasticisers). To simulate a real case scenario and to get better measurement accuracy, all samples were injection moulded. The analysis of the samples was performed using X-ray fluorescence spectrometry (XRF), Inductively coupled plasma (ICP) and Gas chromatography with a Mass spectrometer (GC-MS). All the processing and analysis (except for SCCP/MCCP)) were done by RISE which gives good control over the analysis process, which are important when interpreting the results. In total 54 samples of PE, PP, ABS and PS, were gathered and tested. It was found that all but two samples contained legacy chemicals below the regulated values. The two samples that did not meet the legal limit had a HBCDD content above 100 ppm. All the tested materials contained detectable amounts of bromine, and 15 samples contained detectable amounts of regulated BFRs. None of the detected regulated BRFs were above 186 ppm.  Most of the materials also contained detectable amounts of cadmium and lead.

    Photochromic mesostructured silica pigments dispersed in latex films2005In: Journal of Materials Chemistry, ISSN 0959-9428, E-ISSN 1364-5501, Vol. 15, no 0149-2136, p. 3507-3513Article in journal (Refereed)
    Abstract [en]

    We have incorporated the photochromic dyes spiropyran and spirooxazine in surfactant templated mesostructured silica particles. Spherical inorganic–organic hybrid pigments with varying dye content were produced by a one-pot synthesis in an aerosol reactor where the internal mesostructure could be controlled. The mesostructured inorganic–organic hybrid pigments provide a mechanically and chemically rigid framework that protects the dyes and facilitate handling. We show that an organic latex binder can be used to prepare transparent photochromic films of varying thickness. Changing the dye loading in the pigments and the pigment content in the films provides a versatile route for tuning the photochromic response. The pigmented films show both fast and direct photochromism, where the decay time for thermal bleaching is very fast in the case of spirooxazine doped pigments (kSO= 0.094 s–1), being in the range of the best reported values for solid state composites.

    Structural features and adsorption behaviour of mesoporous silica particles formed from droplets generated in a spraying chamber2004In: Microporous and Mesoporous Materials, ISSN 1387-1811, E-ISSN 1873-3093, Vol. 72, p. 175-183Article in journal (Refereed)
    Abstract [en]

    Spherical mesoporous particles have been produced by spraying hydrolysed alkoxide solutions containing templating amphiphilic molecules. The modified spray drying method produces up to 10 g/h of spherical non-hollow particles with a size of 1–5 m. Transmission electron microscopy and X-ray diffraction showed that well ordered internal 2D hexagonal mesostructures could be prepared using both nonionic block copolymers and cationic surfactants as the templating molecules. Disordered cubic and well ordered lamellar, onion like, particles were prepared from the block copolymer templates. Nitrogen sorption data and mercury porosimetry show that pore size distribution of the mesoporous particles is very narrow with pore sizes varying from 2.5 to 8.5 nm as a function of templating amphiphiles. We have shown that the mesoscopic pores are accessible after calcination and can be filled with relatively large molecules; the particles adsorbed more than 20% (by weight) of the cationic dye Janus Green B from aqueous solutions.

    Combined emulsion and solvent evaporation (ESE) synthesis route to well-ordered mesoporous materials2007In: Langmuir, ISSN 0743-7463, E-ISSN 1520-5827, Vol. 23, no 3, p. 1459-1464Article in journal (Refereed)
    Abstract [en]

    Control over morphology and internal mesostructure of surfactant templated silicas remains a challenge, especially when considering scaling laboratory syntheses up to industrial volumes. Herewereport a method combining emulsification with the evaporation-induced self-assembly (EISA) method for preparing spherical, mesoporous silica particles. This emulsion and solvent evaporation (ESE) method has several potential advantages over classic precipitation routes: it is easily scaled while providing superior control over stoichiometric homogeneity of templating surfactants and inorganic precursors, and particle sizes and distributions are determined by principles developed for manipulating droplet sizes within water-in-oil emulsions. To demonstrate the method, triblock copolymer P104 is used as a templating amphiphile, generating unusually well-ordered 2D hexagonal (P6mm) mesoporous silica, while particle sizes and morphologies were controlled by varying the type of emulsifier and the method for emulsification

    One-pot synthesis of well ordered mesoporous magnetic carriers2007In: Journal of Materials Chemistry A, ISSN 2050-7488, Vol. 17, no 26, p. 2700-2705Article in journal (Refereed)
    Abstract [en]

    The facile preparation of a mesoporous magnetic carrier technology is demonstrated. The micron-sized spherical mesostructured particles are prepared using a newly-developed, one-step, combined emulsion and solvent evaporation (ESE) method. The surfactant-templated silica matrix display a well-ordered internal pore architecture. Very limited pore blocking, and only to a limited degree disordered- or worm-like structures are observed, induced by the iron oxide nanoparticles added to provide the superparamagnetic properties.The iron oxide content was precisely controlled, and the magnetic properties were well preserved during the process. Finally we demonstrate the applicability of the magnetically separable mesoporous material as an adsorbent for specific dissolved materials from dilute aqueous solutions.

    Experimental measurements and numerical simulations of distortions of overlap laser-welded thin sheet steel beam structures2017In: Welding in the World, ISSN 0043-2288, E-ISSN 1878-6669, Vol. 61, no 5, p. 927-934Article in journal (Refereed)
    Abstract [en]

    Distortions of mild steel structures caused by laser welding were analyzed. One thousand-millimeter U-beam structures were welded as overlap joints with different process parameters and thickness configurations. Final vertical and transverse distortions after cooling were measured along the U-beam. Significant factors, which affect distortions, were identified. Heat input per unit length, weld length, and sheet thickness showed a significant effect on welding distortions. Furthermore, the welding distortions were modeled using FE simulations. A simplified and computationally efficient simulation method was used. It describes the effect of shrinkage of the weld zone during cooling. The simulations show reasonable computation times and good agreement with experiments.

    Experiments and efficient simulations of distortions of laser beam–welded thin-sheet close beam steel structures2018In: Proceedings of the Institution of mechanical engineers. Part B, journal of engineering manufacture, ISSN 0954-4054, E-ISSN 2041-2975, Vol. 233, no 3, p. 787-796Article in journal (Refereed)
    Abstract [en]

    In this article, geometrical distortions of steel structures due to laser beam welding were analyzed. Two 700-mm-long U-beam structures were welded in overlap configurations: a double U-beam structure and a U-beam/flat structure. The structures were in different material combinations from mild steel to ultrahigh-strength steel welded with different process parameters. Different measures of distortions of the U-beam structures were evaluated after cooling. Significant factors of the welding process and the geometry of the structures were identified. Furthermore, welding distortions were modeled using two predictive finite element simulation models. The previously known shrinkage method and a newly developed time-efficient simulation method were evaluated. The new model describes the effects of expansion and shrinkage of the weld zone during welding and material plasticity at elevated temperatures. The new simulation method has reasonable computation times for industrial applications and improved agreement with experiments compared to the often used so-called shrinkage method.

    Printable All-Organic Electrochromic Active-Matrix Displays2007In: Advanced Functional Materials, ISSN 1616-301X, E-ISSN 1616-3028, Vol. 17, no 16, p. 3074-Article in journal (Refereed)
    Abstract [en]

    All-organic active matrix addressed displays based on electrochemical smart pixels made on flexible substrates are reported. Each individual smart pixel device combines an electrochemical transistor with an electrochromic display cell, thus resulting in a low-voltage operating robust display technology. Poly(3,4-ethylenedioxythiophene) (PEDOT) doped with poly(styrenesulfonate) (PSS) served as the active material in the electrochemical smart pixels, as well as the conducting lines, of the monolithically integrated active-matrix display. Different active-matrix display addressing schemes have been investigated a matrix display fill factor of 65€‰% was reached. This is achieved by combining a three-terminal electrochemical transistor with an electrochromic display cell architecture, in which an additional layer of PEDOT:PSS was placed on top of the display cell counter electrode. In addition, we have evaluated different kinds of electrochromic polymer materials aiming at reaching a high color switch contrast. This work has been carried out in the light of achieving a robust display technology that is easily manufactured using a standard label printing press, which forced us to use the fewest different materials as well as avoiding exotic complex device architectures. Together, this yields a manufacturing process of only five discrete patterning steps, which in turn promise for that the active matrix addressed displays can be manufactured on paper or plastic substrates in a roll-to-roll production procedure._x000D_

    Microlubrication effect by laser-textured steel surfaces2007In: Wear, ISSN 0043-1648, E-ISSN 1873-2577, Vol. 262, p. 369-379Article in journal (Refereed)
    Abstract [en]

    The beneficial effect on lubrication achieved through microtexturing by laser ablation was investigated. The investigation was based on two independent experimental approaches with oil-lubricated smooth and laser-textured steel surfaces in oscillating sliding contact with a steel ball. Two types of laser-textured patterns of microcavities were studied. It was found that, in comparison with smooth steel surfaces, the laser texturing significantly reduces friction and wear. The most significant improvement in the tribological performance was achieved with an oil of high viscosity combined with a texture comprising a low density of deep microcavities.

    Hot rolling tests with steel bars and silicon nitride rolls2009In: Journal of Materials Processing Technology, ISSN 0924-0136, E-ISSN 1873-4774, Vol. 209, no 2, p. 884-893Article in journal (Refereed)
    Abstract [en]

    An experimental study was carried out to investigate the possibilities to use rolls made from Si3N4-TiN ceramic composite in hot rolling of steel. The results show that the wear of the ceramic material was lower than the wear of a reference cast iron. The results suggest that the Si3N4-TiN material is beneficial to use in a hot rolling process, on condition that the temperature of the work piece material is held sufficiently high. © 2008 Elsevier B.V.

    Transfer of surface texture from silicon nitride rolls to stainless steel wire in cold-rolling2006In: Journal of Materials Processing Technology, ISSN 0924-0136, E-ISSN 1873-4774, Vol. 173, no 3, p. 394-400Article in journal (Refereed)
    Abstract [en]

    A set of cold-rolling experiments with ceramic rolls was carried out using facilities for the production of profiled steel wire. Based on the experiments, the strength of sintered silicon nitride was found sufficient for allowing cold-rolling of austenitic stainless steel wire. The wear rate of the silicon nitride rolls in the tests was low. Metal was transferred from the wire to the rolling tracks of the ceramic rolls. The surface texture of the rolls was reproduced on the rolled product. © 2006 Elsevier B.V. All rights reserved.

    Värmeledningsförmåga hos formmaterial2011Report (Refereed)
    Abstract [sv]

    I den första delen av studien tillverkades och bestämdes värmeledningsförmågan för samtliga provkroppar i olika kvarts/fältspatsander från Baskarpsand. Sanderna skiljer sig åt i medelkornstorlek och kornstorleksfördelning. Två olika självhärdande bindemedel, alfaset och furan, användes. I studiens senare del tillverkades och bestämdes värmeledningsförmågan för provkroppar också i sander baserade på andra mineraler. Dessutom undersöktes ytterligare ett bindemedel, nämligen Coldbox. Resultat för Coldbox redovisas i rapporten, då den inte kommer att ingå i någon publikation. Resultaten från de övriga försök kommer att publiceras i en vetenskaplig tidskrift inom något av områdena gjuteriteknik eller mineralogi. För att tillgodose de tilltänka tidskrifternas publiceringsregler, redovisas inte resultaten för dessa i denna rapport.
