Research Progress in Surface Modification of Biomedical Ti6Al4V Alloy

Ti6Al4V alloy is extensively applied in the field of the replacement and restoration for surgical implants owning to its excellent mechanical performance and good biocompatibility. However, because of the poor wear resistance, bio-activity and so on, it is really important to modify the surface of Ti6Al4V alloy. This paper introduces the effective methods to improve the properties, and summarizes the research achievement of surface modification. The development trend of surface modification is prospected.
