目的：提高医用钛合金的耐磨损性能。方法应用等离子渗氮技术在Ti13 Nb13 Zr基材上制备改性层,并对改性层组织、成分及硬度进行测试。利用往复磨损试验机研究改性层在干摩擦条件下的摩擦磨损性能,并与未处理的基材进行对比。结果 Ti13 Nb13 Zr合金表面经渗氮后形成致密均匀的改性层,硬度高达1110 HV0.025,改性层的磨损体积约为基材的1/23。结论等离子渗氮技术有效地改善了Ti13 Nb13 Zr合金的摩擦磨损性能。
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 mi-crohardness 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.
