研究了AISI 316L不锈钢在不同工艺条件下电抛光（EP）和磁电抛光（MEP）后表面膜的组成。在自然对流（静止电解液中）和强制对流（低于0.1 m/s的中等搅拌）下，在极化平台和更高的极化平台上进行了电抛光EP过程。通过机械磨料抛光制备的具有1000粒度的样品用作参考。Cr：还研究了不同制备的样品的Fe比率，并且发现EP和MEP样品的该比率显著高于机械抛光的样品。在此基础上，制定了合适的电解抛光条件的选择。(C)2010 Elsevier B. V.保留所有权利。
The aim of the paper is to present the surface film composition formed on AISI 316L stainless steel after electropolishing (EP) and magnetoelectropolishing (MEP) for a wide range of the process conditions. The electropolishing EP process has been performed under natural convection (in still electrolyte), and under a forced convection (moderate stirring below 0.1 m/s), both at the polarization plateaux and much above it. Another series of experiments were carried out on AISI 316L SS samples prepared by MEP at 350 mT. The samples prepared by mechanical abrasive polishing, with the grit size of 1000 served as a reference. The Cr: Fe ratio was also studied for the differently prepared samples and it was found that this ratio was significantly higher for the EP and MEP samples than the mechanically polished one. Based on the results, the selection of proper electropolishing conditions have been formulated. (C) 2010 Elsevier B.V. All rights reserved.
