✦ Synopsis

Anodic polarization measurements of several orthopaedic implant alloys-AISI 316L stainless steel, Co-Cr-Mo alloy (ASTM F-75), nickel-titanium (NiTi) alloy, commercial pure titanium, and Ti-6Al-4V-were carried out in Ringer's solution containing 1% bovine serum albumin (BSA) and in simple Ringer's solution. Constituent metals in the medium were analyzed by inductively coupled plasma emission spectrophotometry after measurements. Pitting potentials and total anodic current of former two alloys were constant in the two mediums and not affected by the addition of bovine serum albumin. However, the amount of dissolved metals from pure nickel and AISI 316L stainless steel were increased by the addition of BSA, dissolved metals from Co-Cr-Mo alloy were decreased by it.
