摘　　要：汽车凸轮轴控制发动机的进排气门,其常见的失效形式是凸轮磨损,凸轮的耐磨性对凸轮轴的使用寿命有着重要影响。介绍了凸轮材料的摩擦磨损测试方法,铸造、锻造、粉末冶金凸轮材料的摩擦磨损性能的研究现状和显微组织对其耐磨性的影响,并归纳了凸轮材料的摩擦磨损机理,最后对凸轮磨损机理的研究提出建议。The automobile camshaft controls the intake and exhaust valves of the engine. The common failure mode of the camshaft is cam wear. The wear resistance of the cam has an important influence on the service life of the camshaft. The friction and wear testing methods of cam materials were introduced,the research status of friction and wear properties of casting,forging and powder metallurgy cam materials and the influence of microstructure on their wear resistance were discussed,the friction and wear mechanism of cam materials were also summarized,and some suggestions on the research of cam wear mechanism were finally put forward.
