Improvement of corrosion-wear resistance of Ti-6Al-4V alloy by plasma Mo-N surface modification

Ti‐6Al‐4V alloy has attracted increasing applications as a metallic biomaterial in recent years thanks to its good corrosion resistance and biocompatibility. However, the poor corrosion‐wear resistance of the alloy is thus a major concern to potential users. In this paper, the electrochemical noise technique is used as an on‐line tool to investigate the corrosion‐wear behavior of untreated and Mo‐N modified Ti‐6Al‐4V alloy sliding against corundum in Hanks' and sodium phosphate solutions.status: publishe
