    Ti-6Al-4V alloy has been extensively used in orthopaedic implants because of its high strength, good corrosion resistance, and excellent biocompatibility in comparison to other implant materials. In this investigation, mechanical and corrosion properties of nitrogen diffusion hardened Ti-6Al-4V alloy have been evaluated with an objective of using this surface hardening treatment for orthopaedic implants. The properties evaluated were hardness, tensile strength, fatigue strength, wear, surface wettability and corrosion resistance of the alloy. The results of this investigation indicated hardness, surface wettability and wear resistance of Ti-6Al-4V alloy are substantially increased by the surface hardening treatment, while tensile, fatigue, and corrosion properties of the alloy are unchanged. The enhancement of wear resistance of Ti-6Al-4V alloy by the surface hardening treatment makes it attractive for applications to hip and knee prostheses.
