电荷调制电化学加工（CM-ECM）过程由电荷调制电场波形控制。在难切削材料（如镍基合金和铝铸造合金等硬质被动材料）的加工和精加工中，它提高了金属去除率、尺寸精度和表面质量。本文介绍了一种有效的硬质被动合金表面精加工工艺，使用CM-ECM工艺去除先前制造工艺留下的受损表面层、缺陷或边缘毛刺。实验结果表明，CM-ECM工艺可用于不同材料的抛光和去毛刺等多种表面精加工。

The charge modulated electrochemical machining (CM-ECM) process is controlled by a charge modulated electric field waveform. It improves metal removal rate, dimensional accuracy, and surface quality in machining and finishing of difficult-to-cut materials, like hard, passive materials such as nickel-base alloys and aluminum casting alloys. This paper presents an effective surface finishing process for hard, passive alloys using the CM-ECM process to remove the damaged surface layer, defects, or edge burrs left by prior manufacturing processing. The experimental results indicate that the CM-ECM process can be used for variety of surface finishing such as polishing and deburring for different materials.
