摘　　要：针对某航天产品电解刻蚀过程中存在的质量不稳定现象,从电解刻蚀的原理出发,对产品加工过程中可能存在问题的环节进行了深入分析,采取了降低浓差极化的措施,改变了电解液流场,同时对电解液浓度配比进行调整,使产品质量得到极大提高。Aiming at the quality instability of an aerospace product eletrolytic etching process, the steps with possible problems are analyzed from the principle of electrolytic etching. Measures are taken to reduce the concentration polarization and change the electrolyte flow field. Meanwhile, the electro- lyte concentration ratio is adjusted. The product quality has been greatly improved therefore.
