Electropolishing of stainless steel

Abstract

Three different electropolishing baths were formulated in H3PO4H2SO4 medium with mono, di and triethanolamines as additives for polishing of stainless steel panels. For each bath, the polishing current densities were fixed through Hull Cell experiments. The effect of varying current density, temperature and electroplating duration were studied for these baths. The specular reflectance measurements were made to assess the extent of polishing under different experimental conditions. A detailed analysis of the experimental results is presented.
