摘要(Abstract)：

石墨添加量是影响Cu基复合材料摩擦学性能的关键因素之一。为此，研究了镀Ni石墨含量(2、4、6和8 mass%)对镀Ni石墨/Cu复合材料摩擦学行为的影响，分析了石墨含量与复合材料的微观组织、物理性能及硬度的关系，以确定最佳的石墨添加量。结果表明：复合材料中石墨与Cu之间的结合性较好，没有出现明显的空隙和裂纹；随镀Ni石墨由2 mass%增加到8 mass%,复合材料的致密度和导电率分别减小了3.7%和43.5%,硬度先由60.3 HV0.1增大到63.4 HV0.1后再减小到59.7 HV0.1,其中转折点在6 mass%镀Ni石墨，而摩擦系数和磨损率均为先减小后增大。因此，理想的镀Ni石墨添加量为6 mass%,此时，复合材料的磨损机制以磨粒磨损为主，粘着和氧化磨损为辅。
