“…7 Each electrode was electropolished to remove the deformation layer generated during mechanical polishing. 3,8 It is reported that electropolishing does not alter the surface crystallographic orientation of Al electrodes. 3 The electropolishing solution was a stirred perchloric acid ͑15% vol͒/methanol solution, maintained at Ϫ10°C by submerging the glass cell in a thermostated silicon-oil bath.…”

The rate of dissolution, R dis , of the native Al 2 O 3 film on electrochemically polished, single-crystal ͓͑100͒, ͑110͒, and ͑111͒ orientations͔ and polycrystalline Al electrodes is reported. Measurements were made in 50 mM H 3 BO 3 /0.3 mM Na 2 B 4 O 7 •10 H 2 O solutions (pH ϳ 6.7) containing between 0 and 75 mM NaCl. R dis is determined by analysis of voltammetric curves recorded during film growth, using a model in which oxide growth is governed by high-field transport of ions within the film, while oxide dissolution at the oxide/electrolyte interface occurs by a potential-independent mechanism. R dis is observed to be dependent upon the surface orientation in the order: polycrystalline Al Ͼ Al(111) ϳ Al(110) Ͼ Al(100). Small enhancements in both the rate of ion transport within the oxide film and R dis at polycrystalline Al are attributed to lowering of activation barriers at grain boundaries. R dis is also shown to increase with increasing Cl Ϫ concentration, reaching a limiting value at ϳ40 mM, regardless of electrode crystallinity or orientation. The dependence of R dis on Cl Ϫ concentration is consistent with adsorption of Cl Ϫ at the oxide/electrolyte interface, followed by desorption of an AlCl x complex.

“…9 Usually, current and time are the two variables that can be controlled to reach the reproducible surface finish. 10 Electropolishing can be described by the Faraday's laws of electrolysis. Faraday's first law of electrolysis and Faraday's second law of electrolysis state that the amount of a material deposited on an electrode is proportional to the amount of electricity used and the amount of different substances liberated by a given quantity of electricity is proportional to their electrochemical equivalent (or chemical equivalent weight).…”

Electropolishing is the electrochemical process to remove the metallic material from the workpiece, in order to obtain a smoother metal surface. It has found vast engineering applications in many fields, such as food, medical, pharmaceutical and semiconductor industries. This review is aimed to provide the readership with insightful understanding of the electropolishing process, from the fundamental aspects as well as from the application aspects. The general aspects of electropolishing, including its definition, the classic setup, the fundamentals behind it and methods used to evaluate the electropolishing finishes are reviewed here. Various electropolishing theories, be them quantitative or qualitative are briefly discussed. Based on those theories, important parameters evolved in the electropolishing process are enumerated. Many microscopic technologies are used to evaluate the electropolishing surface finishes. This includes optical microscope, electron microscope and atomic force microscope. Some key features of electropolishing are briefly outlined in the end.
