摘要

摘要: 为实现金属表面微结构高精度、高效率、稳定加工，结合微细电解加工技术和气膜保护原理，提出了一种新的加工方法——气膜屏蔽微细电解加工。对气膜屏蔽微细电解加工时气泡产生的分布规律、保护气膜对水跃现象的影响、微凹坑成形形貌进行分析。结果表明，采用相同加工参数下，气膜屏蔽微细电解加工方法相对电化学射流加工方法，加工出的微凹坑表面粗糙度降低了29.4%、深径比增加了85%、杂散腐蚀减少，进一步验证了所提出加工方法的优越性。

Abstract: In order to manufacture the micro-structure of metal with high efficiency and precision, based on the micro-electrochemical machining principle, a new method of gas film shielding electrochemical micro-machining was presented. The distribution of gas bubbles, the influence of gas film on the hydraulic jump and the micro-concave shape machined with the gas film shielding electrochemical micro-machining method were analyzed. The analysis results show that the gas film shielding micro-electrochemical machining method can reduce the surface roughness by 29.4%, increase the depth to diameter ratio by 85%, and reduce the stray corrosion, compared with the electrochemical jet machining method under the condition that the parameters are the same, verifying that the new method is superior.
