| 摘 要： | 研究表明,合理的表面织构可改善活塞汽缸中摩擦副的润滑特性,提高抗磨减摩性能.试验了用电解转印法加工凹坑阵列,对加工中阴阳极之间的封闭区域建立数学模型,并进行了ANSYS电场分析.试验研究了阴极掩模胶膜厚度、加工间隙、加工电压对微坑形貌的影响,通过优化加工参数,提高了微小凹坑阵列的均匀性与微坑加工精度.采用光刻工艺制备了直径为10 μm、厚度为40 μm的阴极掩模,以此进行电解转印加工,可获得平均直径为140 μm、深度为30 μm的凹坑阵列.

| Abstract: | It has been identified that the reasonable surface texturing can p romote friction characteristics of a lubricating film in the cylinder piston.In this paper,an electrochemical machining method with a mask onto the cathode is employed to produce the micro-pits array patterns.The mathematical model of the enclosed area between the cathode and anode is established for the ANSYS analysis of the electric field.The effects of the cathode film thickness,the processing voltage,and the cathode-anode gap on the prof... |
