摘　　要：采用粉末冶金方法制备了铜基功能梯度复合材料。对铜基梯度复合材料的机械性能电性能及摩擦学性能的测试表明:表层与底层组成为Cu-C-MOS_2/Cu-ZrO_2的功能梯度复合材料具有强度高,导电性好,耐磨性好的特点。材料的微观结构和摩擦磨损表面形貌分析表明,铜基功能梯度复合材料界面结合性好,组织均匀;润滑相组织弥散细小。同时兼有优良的机械性能和摩擦磨损性能。Powder metallurgy method was adopted to prepare copper-based functional gradient composite materials. The mechanism and tribology performance of the materials was tested. The result indicated that the material of which surface layer and bottom was made of Cu-C-MoS2/ Cu-ZrO2 had characteristics of high intensity, good electric and wearable performance. The microstructure analysis and friction, abrasion with surface appearance analysis indicated that the interface of copper-based functional gradient composite materials had better combination and uniform structure; the structure of lubricating phase was dispersion and minute. The material was provided with combination of excellent mechanical and tribology performance.
