The Effect of Electrochemical Polishing Time on Surface Topography of Mild Steel

摘要

This paper investigated the variation of the altitude density Junction (ADF) and the autocorrelation Junction (ACF) about the surface profile of mild steel during electrochemical polishing (ECP). The results show that the variation features of ADF with polishing time are flat-steep-flat, and the variation features of ACF with polishing time are random-regular-random. There is a fine surface smoothness at the special period of ECP. Both the original surface and the full ECP surface show an obvious roughness.
