以金属阳极/电解液匹配试验为基础,论述了ηω—i电解液试验方法的可靠性及其意义;分析了超钝化溶解的条件与特征及其对加工精度的影响;对Fe/Cl和Fe/NO_3~-的阳极溶解速度和平衡间隙之间的关系进行了讨论;在系统试验基础上,提供了具有超钝化溶解性能的电解液及其ηω—i规律。 Based on the metal anode / electrolyte matching test, the reliability and significance of the test method of ηω-i electrolyte were discussed. The conditions and characteristics of ultra-passivation dissolution and its influence on the machining accuracy were analyzed. The relationship between anodic dissolution rate and equilibrium gap of Fe / NO_3 ~ - was discussed. Based on systematic experiments, an electrolyte with ultra-passivated dissolution properties and its ηω-i law were provided.
