Commonly Used Electrolytic Polishing Methods And Characteristics In Stainless Steel Pipe Fittings

Stainless steel pipe fittings use metal workpieces as anodes, and are electrolyzed in suitable electrolytes to selectively remove their rough surfaces and improve the surface finish. This technology is also called electrolytic polishing. Electropolishing can increase the corrosion resistance of stainless steel, reduce the resistance of electrical contact points, prepare metallographic grinding discs, improve the reflective performance of lighting fixtures, improve the accuracy of various measuring tools, beautify metal daily necessities and crafts, etc. It is suitable for polishing steel, aluminum, copper, nickel and various alloys.

At the same time, during Stainless Steel Weld Fitting-point electrolytic polishing: the metal ions detached from the workpiece and the phosphoric acid in the polishing liquid form a phosphate film adsorbed on the surface of the workpiece. This mucous film is thinner at the convex part and thicker at the concave part. It dissolves quickly due to the high current density at the convex part. As the mucous film flows, the concave and convex parts change continuously, and the rough surface is gradually leveled. It also has the characteristics of wide processing range, high production efficiency, high processing accuracy, good surface quality, and small grinding wheel wear.
