Stress-Etching Using Laser Electrochemical Micromachining with Masks

Abstract:

Metal workpiece was processed by nanosecond pulsed laser electrochemical micro-etching with masks patterns in the shape of letter "E". In the experimental system established, the effect of different laser energy on processing quality was studied in air. In the different concentrations of the electrolyte, through optimized composite machining parameters, machining results of different laser energy with the masks were analyzed and compared in Aluminum alloy and Stainless steel. There was a large of difference in machining morphology by laser electrochemical micromachining with masks in two different metal materials. The results show that laser electrochemical micro-etching with masks has high efficiency and the prospects for the large-scale production, but the etching precision should be also further improved. Moreover, the nanosecond pulsed laser thermal-stress etching, electrochemical etching and the two combined coupling etching are the main factors to achieve the metal removal.
