摘要(Abstract)：

采用热压烧结法制备弥散铜-MoS2复合材料,研究了复合材料的导电性、力学性能以及载流摩擦磨损性能。结果表明,随着MoS2含量的增加,材料力学性能降低、导电率下降,而耐磨性提升,含3%MoS2复合材料的耐磨性好于含1%MoS2材料。在磨损实验中发现,摩擦副表面形成具有自润滑作用的第三体润滑膜可进一步改善复合材料的耐磨性,该润滑膜是由处在塑性变形阶段的铜与铜钼硫化合物组成,它使得含3%MoS2复合材料在电流为90 A时的磨损率低于电流为30 A时的磨损率。弥散铜-MoS2复合材料的摩擦磨损机制主要是黏着磨损、磨粒磨损及疲劳磨损。

关键词(KeyWords)： 弥散铜-MoS2复合材料;摩擦因数;磨损率
