    Abstract:

    Titanium alloys are still most widely used for biomedical applications. These alloys cannot meet all of the clinical requirements; therefore, various surface modifications have been attempted for improving the specific properties. In this research work nanoporous oxide films were produced on titanium alloys surface using a controlled anodic oxidation treatment. The surface morphology, chemical composition and thickness of the anodically oxidized films on the alloys surface were evaluated. The comparative investigation of untreated titanium alloys surface and porous anodic oxide film growth on titanium alloys was carried out to determine the corrosion and tribocorrosion performances in 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 corrosion and tribo-electrochemical performances of titanium alloys for biomedical applications.
