摘要

将光纤激光表面改性技术和微细电解加工技术相结合,在不锈钢表面加工复杂微细型腔等微小零件。先利用光纤激光在304不锈钢表面制作掩模图案;再利用掩模的耐腐蚀性,在微细电解加工时实现微细型腔的定域加工。研制了光纤激光掩模微细电解的复合加工装置,以304不锈钢为试样,通过工艺对比试验,优化了系统参数。试验结果表明,使用该装置可以快速地加工典型结构的微细型腔。

Abstract

In order to fabricate a microcavity with a complex structure on the surface of stainless steels, the electrochemical micromachining technology based on fiber laser surface modification is adopted. First, the 304 stainless steel surface is masked with a predefined pattern by using a fiber laser. Then, by virtue of the corrosion resistance property of laser masked layers, a microcavity can be locally machined by the electrochemical etching technology. A composite machining system based on electrochemical micromachining in combination with fiber laser masking is developed. The system parameters are optimized through process comparison experiments by using 304 stainless steel as specimens. The results show that a microcavity with any typical structure can be fabricated quickly with this system.
