Different surface treatments, with and without silver (Ag), of a Ti6Al4V alloy for increased bone bonding ability were investigated compared non-treated surfaces. Studies conducted at 37 °C in phosphate buffered saline (PBS, pH 7.4) varying hydrogen peroxide (H2O2) bovine serum albumin (BSA) concentrations. Increased levels metal release corrosion observed the presence both H2O2 BSA due to complexation Ti Al oxide, respectively. Ag was enhanced by BSA. Galvanic effects minor, but possibly most corrosive environment.
