Abstract—The tribotechnical properties of composite materials developed by powder metallurgy methods are studied. Friction tests was carried out in a dry environment on a vertical MMW-1 tribometer by the pin-on-disk mechanism. An Amscope optical microscope was used to analyze the wear surfaces. The experimental results showed that the use of Cu–C (copper–graphite) ~ 10 wt % improves the frictional properties of the composites.

铜-石墨颗粒烧结复合材料的表面结构对其摩擦学性能的影响

摘要—研究了​​粉末冶金方法开发的复合材料的摩擦学性能。摩擦试验是在干燥的环境中，通过销盘式机构在垂直MMW-1摩擦计上进行的。使用Amscope光学显微镜分析磨损表面。实验结果表明，使用约10 wt％的Cu–C（铜－石墨）可改善复合材料的摩擦性能。
