Abstract

The corrosion behaviour of AISI 316L, wrought Co-28Cr-6Mo and Ti-6Al-4V was studied in aerated solutions of phosphate buffered saline (PBS) at various concentrations of bovine serum albumin (BSA) at 37 °C. Open circuit potential, potentiodynamic polarization, linear polarization resistance (LPR) and electrochemical impedance spectroscopy (EIS) experiments along with X-ray photoelectron spectroscopy (XPS) on Co-28Cr-6Mo oxide layer were conducted to study the interaction of BSA and passive layers and to measure the corrosion rates. Ti-6Al-4V alloy had the lowest corrosion rate and the highest breakdown potential. It was shown that BSA has enhanced the alloy passive film stability at higher concentrations.
