摘　　要：利用Ｍ－２００型环-块材料磨损试验机，对机械混合法制备的ＳｉＣ陶瓷颗粒填充聚四氟乙烯（ＰＴＦＥ）复合材料在干摩擦条件下的磨损特性进行了研究，并利用扫描电子显微镜（ＳＥＭ）对ＰＴＦＥ复合材料的磨损表面形貌进行了现察．结果表明出ＳｉＣ颗粒的加入大大提高了ＰＴＦＥ的耐磨性能，颗粒的添加量、磨损载荷、磨损温度是影响复合材料耐磨性能的重要因素．A research about wear properties in dry condition of SiC particles filled PTFE composite material with 45# steel (the formation of quench, tempering in low temperatures) was investigated by using M-200 model friction and wear testing machine. A observation was made by analysis of Scanning Electron Microscope (SEM). The results show that: the amount of wear was greatly reduced by the addition of SiC particles, the amount of SiC particle, the load of wear and the wear temperature are the main factors.
