The present study aims at enhancing the wear resistance and biocompatibility of Ti-6Al-4V by forming a thin layer of oxide. Surface oxidation has been carried out by controlled heating of the surface of Ti-6Al-4V substrate in air at the temperature ranging from 400-600°C and time from 25-60 h. The phase formed under thermal oxidation was predominantly the rutile and anatase phase. The thickness of the oxide layer varied from 1.5-7.0 µm. The microhardness on the surface was significantly improved as compared to the as-received substrate. Both the corrosion resistance property and biocompatibility were improved.
