摘　　要：摩擦副表面一定规则形貌的微凹坑可以改善表面摩擦学特性,提高润滑耐磨性能。根据摩擦学理论,设计圆形微凹坑;用组合电加工方法制作阵列微细轴工具电极;采用多种微细特种加工方法加工出微凹坑,并进行微凹坑加工工艺分析。The micro-pits of working surface between friction pairs with regular profiles can ameliorate the surface tribological properties, improve the lubrication and wear resisting. Based on the tribological theory, circular micro-pit is designed; Array micro-axis electrodes are manufactured by combined electrical machining; then micro-pits are made by different special micro-machining methods. At last, processing technology is analyzed.
