Effects of Plasma Nitriding and TiN Coating Duplex Treatment on Wear Resistance of Commercially Pure Titanium

Abstract:

The commercially pure(CP) titanium specimens were modified with Direct current(DC) plasma nitriding and arc ion plating of TiN film. The duplex treated titanium samples were characterized by scanning electron microscopy(SEM), microhardness tester and ball-on-disc tribotester. The results showed that the duplex treated CP titanium appeared uniform and bright golden, microhardness and wear resistance improved substantially and were superior to that of only TiN coated ones. All these results indicate plasma nitriding and TiN film deposition duplex treatment can improve surface characteristics of CP titanium significantly. The method can be applied to the titanium denture to improve the tribological properties and color.
