Research on Technology of Pulse Electrochemical and its Compound Finishing

Abstract

In this paper, Pulse electrochemical finishing (PECF) and pulse electrochemical compound finishing (PECCF) are introduced. The main technical parameters, including in intereletrode gap, current density, compositions of steel materials and pulse parameters on the resulting surface finish were studied. PECF and PECCF on different surface including plane and shafts surface are done. Well-pleasing experimental results is gained. Results indicate that PECF and PECCF can lead to both good smoothing efficiency and s…
