Researches of influence ultra-fine grained of structure of copper Ml on electrochemical machining in a comparison with initial analog

摘要

The comparison of characteristics of anodic dissolution of copper Ml with ultra-micro-grained structure in a comparison with its coarse-grained analog under conditions of electrochemical machining of metals (ECM) has been carried out. The influence of material structure on ECM characteristics (machining rate, localization coefficient, surface finishing) in chloride and nitrate solutions with different concentrations is shown. It is shown that the influence of material structure is much higher in passivating electrolytes (nitrate solutions) due to the features of surface oxide films shaping
