Magnesium Alloy Surface Treatment Technology

Because magnesium alloy is extremely active, there is often a layer of oxide on the surface, so the surface treatment of magnesium alloy is difficult. Special treatment methods must be adopted. The existing surface treatment technology is not mature, often making the alloy surface rough and using a large number of non -environmental chemicals. In recent years, the advanced surface treatment technology of magnesium alloy has developed new development.

The technology developed includes three parts: electroplating, conversion layer and anode oxidation. The surface treatment of magnesium alloys is mainly to improve the appearance of the product and improve wear resistance and anti -corrosion performance. The function has the following points:

(A) Decorative surface;

(B) Form a protective layer to prevent magnesium alloy being exposed to the air;

(C) Fill and modify the surface small holes of the die castings;

(D) Increase the adhesion between the magnesium alloy substrate and the organic coating;

(E) Improve wear resistance;

(F) I isolation of magnesium alloys and other metals to prevent electrochemical corrosion.
