| 摘 要： | 采用冷压烧结方法制备了碳纤维增强铜合金复合材料(Cf/Cu-Sn-Zn)和ZQSn663锡青铜.对摩擦磨损性能进行了对比研究,并对磨损机理进行了讨论.实验结果表明,Cf/Cu-Sn-Zn复合材料的磨损率和摩擦系数低于ZQSn663锡青铜.当碳纤维体积含量达到12%时,复合材料的摩擦磨损性能达到最佳.SEM和EDS分析结果表明,ZQSn663锡青铜的磨损机制主要是黏着磨损.Cf/Cu-Sn-Zn复合材料的磨损是黏着磨损和氧化磨损共同作用的结果.

| Abstract: | Short carbon fiber reinforced copper alloy matrix composites and bronze with composition of Cu,6%Sn,6%Zn and 3%Pb(663 bronze)were prepared by cold pressing and sintering methods.The tribological performance was investigated.The results indicate that wear rate and friction coefficient of the Cf/Cu-Sn-Zn composite were lower than that of 663 bronze.SEM and EDS indicate that the dominant wear mechanism for 663 bronze was adhesive wear,while for Cf/Cu-Sn-Zn composites was adhesive wear accompanied by oxidative ... |
