Difference between electrolytic polishing and electrochemical polishing

There is no difference between electrolytic polishing and electrochemical polishing.

Electrochemical polishing is also called electrolytic polishing. Electrolytic polishing takes the workpiece as anode and insoluble metal as cathode. Both electrodes are immersed in the electrolytic cell at the same time, and direct current is applied to produce selective anodic dissolution, thus achieving the effect of increasing the surface brightness of the workpiece.

Advantages of electrolytic polishing:

1, the internal and external colors are consistent, the luster is lasting, and the depressions that cannot be thrown away by mechanical polishing can also be leveled.

2, high production efficiency and low cost.

3, increase the corrosion resistance of the workpiece surface.

Extended data

function

Electrolytic polishing is a method of metal surface processing. It is a process in which metal products suspended in an electrolytic cell are used as anodes, electrolysis is carried out under specific conditions, and the surface roughness of the products is eliminated through the dissolution of anode metal, so that they have a mirror-like luster appearance.

This method is often used to improve the surface smoothness of aluminum and its alloys, carbon steel, stainless steel and other non-ferrous metals to meet the needs of some parts under working conditions (such as reducing the friction coefficient of the surface and requiring precise tolerance fit). ) and improve the decorative appearance of metal products.

Electro-polishing can also remove some mechanical damage on the metal surface. Compared with mechanical polishing, the surface after electrolytic polishing has no stress. However, the surface that is too rough is not suitable for direct electrolytic polishing.
