Biotribocorrosion performance of titanium alloy Ti-6AI-4V and stainless steel 316l under simulated body environment

Tribological problems and corrosion degradation have been recognized as essential risks for total joint replacement, especially for metal arthroplasty. Degradation of the metals and alloys used in bearing surface in joint implants results from a combination of electrochemical and mechanical effects....
