α + β Ti6Al4V samples were exposed to a phosphate buffer saline (PBS) solution containing 1 M of H2O2 for short durations (30 min) to investigate the initial stage of the β phase dissolution. Electrochemical impedance spectroscopy (EIS) measurements and post-mortem scanning electron microscopy (SEM) analysis of the samples revealed randomness in the initiation of β phase dissolution. Bright-field transmission electron microscopy (BF-TEM) imaging and scanning kelvin probe force microscopy (SKPFM) measurements suggested a galvanic coupling between the α and β phases
