摘　　要：在摩擦副表面加工一定规则形貌的微凹坑可改善表面摩擦特性,提高润滑、耐磨性能。根据摩擦学理论,设计了正方形、菱形、圆形等多种截面、形状的微凹坑;用组合电加工方法制作微凹坑加工工具———微凸起电极;采用多种微细特种加工方法加工出多种形状微凹坑,并进行了微凹坑加工工艺分析。The micro-pits of working surface between friction pairs with regular profiles can modify surface tribology character, improve lubrication and wear-resisting. Based on the tribology theory, several micro-pits with the shapes of square, rhombus and cylinder are designed; micro-protrude electrodes are manufactured by combined electrical machining; then micro-pits are made by different nontraditional micro-machining methods. At last, processing technology are analyzed.
