The effect of anodic oxidation treatment of Ti-10Zr alloy on tribocorrosion behavior in a simulated physiological solution

In this study, comparative investigation of untreated Ti-10Zr alloy surface and porous anodic oxide film growth on Ti-10Zr was carried out to determine the tribocorrosion performance in a simulated physiological solution. The in situ electrochemical technique used for investigation of tribo-electrochemical degradation was the open circuit potential (OCP) measurement performed before, during and after sliding tests. The results show that controlled anodic oxidation techniques applied can significantly enhance the tribo-electrochemical performances of Ti-10Zr alloy surface for biomedical applications.
