摘要(Abstract)：

通过在石墨表面镀铜预处理获得Cu包覆的石墨粉末,并以电解铜粉、鳞片石墨粉和Cu包覆石墨粉末为原料,利用ZT-40-20Y真空热压烧结炉制备了鳞片石墨-铜和镀铜石墨-铜复合材料,随后在不同载荷(5、7、9和11 N)下对复合材料进行往复摩擦磨损试验,研究两种复合材料的微观结构、力学性能和不同载荷下的摩擦磨损性能。结果表明:在相同的制备条件下,镀铜石墨有效地改善了镀铜石墨-铜复合材料中C、Cu之间润湿性的问题,使得其致密度、硬度显著提高;在相同的摩擦条件下,镀铜石墨-铜复合材料平均摩擦系数略有提高、而磨损率显著降低,表现出优良的耐摩擦磨损性能;在不同载荷下的往复摩擦试验中,鳞片石墨-铜复合材料主要磨损机制为磨粒磨损、剥落磨损和粘着磨损;而镀铜石墨-铜复合材料主要的磨损机制为磨粒磨损和少量剥落磨损。
