Tribocorrosion behavior of Ti64-xTa alloys fabricated through powder metallurgy

•Ti64-Ta alloys were successfully fabricated through solid-state sintering.•Corrosion performance was enhanced by Ta addition.•Higher corrosion potential drops were observed for Ti64-Ta alloys as compared to Ti64.•Low Ta additions decreased the wear rates of alloys during tribocorrosion.•Ti64-Ta alloys with low Ta additions are suggested for implant fabrication.
