摘要(Abstract)：

采用热压烧结工艺制备了不同Cr_3C_2含量的石墨/Cr_3C_2共增强镍基复合材料，探究了不同Cr_3C_2含量的复合材料的微观结构、力学性能和摩擦性能。结果表明：热压烧结制备的镍基复合材料致密无孔隙，Cr_3C_2和石墨均匀分布于基体内部，异质界面结合良好。随着Cr_3C_2含量的增加，复合材料的割裂程度增加，硬度增加，但强度降低，断裂机制为脆性断裂。摩擦过程中，石墨具有良好的润滑作用，但Cr_3C_2造成磨粒磨损，且随着Cr_3C_2含量的升高，复合材料的摩擦系数和磨损率显著升高。

关键词(KeyWords)： 镍基复合材料;微观结构;力学性能;摩擦学特性
