| Abstract: |
| Objective To improve the wear resistance of medical titanium alloys. Methods Nitride modified layer was fabricated on the surface of Ti13Nb13Zr alloy via plasma nitriding technique. The microstructure distribution, chemical composition and microhardness of the modified layer were characterized. The friction and wear behavior of the modified layer and untreated substrate was investigated under dry friction condition with a reciprocating friction and wear machine. Results A modified layer with smooth and dense structure was formed on the Ti13Nb13Zr surface after plasma nitriding, and the surface hardness reached up to 1110HV0. 025. The wear volume of nitride layer was one twenty-third that of untreated titanium alloy. Conclusion Plasma nitriding could greatly improve the friction and wear resistance of Ti13Nb13Zr titanium alloy. |
