摘　　要：主要考察了添加少量铜元素对钛基合金材料腐蚀和磨损性能的影响。采用球-盘摩擦磨损试验仪研究了合金的摩擦磨损性能,并用SEM和EDS对其磨痕形貌进行观察和分析;采用电化学方法研究了合金在模拟人工体液中的电化学行为,并结合其腐蚀形貌对其耐腐蚀性能进行评估。结果表明,Ti-2Cu的耐磨性能明显优于Ti-1Cu和Ti-3.5Cu合金;钛基合金的耐腐蚀性随着Cu含量的增加而得到有效提高,Ti-3.5Cu>Ti-2Cu>Ti-1Cu。In this paper,the effects of adding a small amount of copper on the corrosion and wear properties of titanium-based alloys were investigated.The friction and wear properties of the alloy were studied by ball-disc wear tester.The morphology after wear of the alloy were observed and analyzed by SEM and EDS.The electrochemical behavior of the alloy in artificial body fluid was studied by electrochemical method,and its corrosion resistance was evaluated by the corrosion morphology.The results show that the wear resistance of Ti-2Cu is better than Ti-1Cu and Ti-3.5Cu.The corrosion resistance of titanium-based alloys improved with the increase ofCu content：Ti-3.5Cu〉Ti-2Cu〉Ti-1Cu.
