| Abstract: | In order to improve the corrosion resistance and micro hardness of AZ91D magnesium, a protecting aluminum and zinc coating on the magnesium alloy surface is obtained by electro-arc spraying. The coating structure has been observed and analyzed with SEM. The result shows that the coating is made up of the mechanical mixture of aiuminum and zinc. The coating combines with the base very well, and it has higher microhardness and the resistance corrosion of magnesium is improved greatly. |
