Ti6Al4V alloy has become the prevailing material for medical implants owing to its good biocompatibility, comprehensive mechanical and process performance, but the corrosiveness of human body fluids could cause Ti6Al4V alloys to corrode and release metal ions that are toxic to the human body. Aimed at this issue, the effects of corrosion behavior of implanted material Ti6Al4V alloy on human body were analyzed in clinical applications, with the research progress on anti-corrosion reviewed, and some suggestions on the surface modification of the material being put forward.
