Principle Of Electrolytic Polishing Of Stainless Steel
The principle of electrolytic polishing of stainless steel is mainly recognized as mucosal theory. The theory is mainly as follows: metal ions separated from the workpiece and phosphoric acid in the polishing fluid form a phosphate film and adsorb it on the surface of the workpiece.
This mucosa is thinner at the convex and thicker at the concave, and dissolves quickly due to the high current density at the convex. With the flow of the mucosa, the concave and convex change constantly, and the rough surface is gradually flattened.
Advantages:
(1)The internal and external color is consistent, lasting luster, mechanical polishing can not be thrown into the concave can also be leveled.
(2)High production efficiency, low cost.
(3) Increase the corrosion resistance of the workpiece surface, suitable for all stainless steel materials.
