Abstract

       The brush electropolishing process is the actual industrial production of equipmentused in the currently limited reference, to guide future industrial production, brushelectropolishing experiments on SUS 304 stainless steel plates, first selected the liquidflow, after the use of the single‐factor method were studied different current density,polishing time, temperature three process parameters on SUS 304 stainless steel afterelectro‐polishing treatment. The effect of the surface quality of SUS 304 stainless steelafter electropolishing was investigated using a single‐factor method, and the difference in roughness Ra before and after electropolishing was used to determine the optimum process parameters. Based on the single‐factor results, orthogonal experiments were carried out to find that the influence of each process parameter on the difference in roughness was ranked as current density > temperature > polishing time. The final results show that when the current density is 42 A/dm2, the electrolyte temperature is 50 °C and the polishing time is 105 s, the surface quality of the sample after electro‐polishing is very good and the final roughness is 0.064 μm, which is mirror bright and the corrosion resistance is greatly improved compared to that before electropolishing,which provides a basis for the use of the brushing process in the future.
