Titanium alloys are widely used in the field of orthopaedics, however, poor tribological performance arising from low shear resistance and weak protection oxide layer limits their applicability. In this work, tribocorrosion behaviour novel ? ? + biomedical titanium were studied bovine serum solution under open circuit potential. Ti-5Mo-Fe-3Sn Ti-6Al-4V ELI found to have capability repassivate w...
