摘要
分析了Al-Al2O3模板阴极法微细电解加工材料去除机理,开展了相关试验验证工作。选择陶瓷层厚度为70、150、200μm的铝板作为阴极,工件材料分别为不锈钢和纯钛,进行电解加工试验。结果表明:陶瓷层越厚,侧向腐蚀越小,成形精度越高,但相对加工效率有所降低。采用孔径500μm的Al-Al2O3模板,成功制备出平均孔径554.7μm和575.8μm的不锈钢工件及纯钛工件。
The material removal mechanism of micro-ECM by using Al-Al2 O3 mask cathode is ana- lyzed, and the relative experimental work has been fulfilled. The Al-Al2O3 masks with different thick- ness of insulation layer （70μm, 150μm and 200 μm respectively ） have been selected as cathode for electrochemical machining of stainless steel and titanium foil. It is demonstrated that with the thicker insulation layer, the undercut is smaller, and the forming accuracy of ECMed holes is better as well, however, the efficiency is relatively lower. With the same mask of 500 μm in diameter, the array of micro holes have bee successfully fabricated, for SUS304 stainless steel, the average diameter is 554.7 μm, and for titanium, the average diameter is 575.8 μm.
