What is electrolytic polishing of stainless steel

Electrolytic polishing of stainless steel is a method of polishing the surface of stainless steel workpiece.The workpiece to be polished is used as anode, and the insoluble metal as cathode.The two poles are immersed in the electrolytic cell at the same time, and direct current is applied to produce selective anode dissolution.The workpiece surface flattens out.So as to increase the workpiece surface brightness effect.

The principle of electrolytic polishing of stainless steel is recognized as the mucosal theory.The main principle is: the metal ions stripped from the workpiece and the phosphoric acid in the polishing solution form a phosphoric acid film, which is absorbed on the workpiece surface.Due to the high current density, convex mucosa is thinner and concave mucosa is thicker.The dissolution process is fast. With the flow of mucosa, the non-uniformity changes constantly and the rough surface flattens gradually.

(1) The internal and external color is consistent, luster lasting, mechanical polishing can not drop the concave can also be flat.

⑵ High production efficiency and low cost.

(3) Increase the corrosion resistance of the workpiece surface, suitable for all stainless steel materials.
