A Study of Precision Current Efficiency Curve Measurement with a Casing-Type Anode

Electrochemical machining (ECM) is a non-traditional technology that widely used in the manufacturing of key components aviation industry. The current efficiency defined as ratio observed amount dissolved metal to theoretical predicted from Faraday’s law. In ECM, curve relates dissolution rate anode material and density. Accurate measurement basis for shape prediction cathode tool design. However, conventional methods, phenomenon edge stray corrosion introduces significant errors. Improving thus challenging task any electrophysical or electrochemical process. To improve accuracy, this paper proposes with casing-type anode. proposed method, designed two parts: mandril casing. effect mainly concentrated on casing, only distribution considered calculation efficiency. simulations methods were carried out. simulation results show method significantly improves accuracy measurements, 304SS was obtained.
