Abstract:	摘要： As a popular application of electrochemical anodic dissolution, electropolishing is extensively adopted in the surface finishing industries of metals. Anodic dissolution is a complex reaction with many process parameters and chemical properties involved. A simple explanation of the mechanism of morphology formation during the EP reaction is still lacking. This study examines the morphology formation of stainless steel 304 at the same location on the specimen as the process evolves. Based on these observations, the basic mechanisms of morphology formation in EP process are proposed. The bubble shielding effect (BSE) and the broken bubble tunnelling effect (BBTE) explain the raised and dented morphologies, respectively. The broken bubble tunnelling effect (BBTE) explains the formation mechanism of pitting holes and the bubble shielding effect (BSE) explains the limitation of surface roughness of electropolishing process. Simulation results are consistent with the observed morphology formation phenomena. 出版者： Elsevier B.V 出版日期： 2012-12-01 出處： International Journal of Electrochemical Science, 2012-12, Vol.7 (12), p.12495-12506 資源來源： Alma/SFX Local Collection 版權： 2012 The Authors.
