Abstract

In order to provide an effective anticorrosive Cu-based coating for magnesium alloy, cold spray and ultrasonic shot peening (USSP) were used. A series of Cu/Ni composite coatings with different content of Ni were deposited on the surface of the Mg alloy. The obtained coatings were strengthened by USSP. The results revealed that the structural compactness and protecting effect of the cold-sprayed pure Cu coating was enhanced by USSP. The micro-hardness values of the Cu/Ni composite coatings were increased with the Ni content. The 16 vol.% Ni powders improved the corrosion resistance of the cold-sprayed pure Cu coating. Thus, the cold-sprayed Cu/Ni composite coating with excellent mechanical properties and corrosion resistance can be applied to magnesium alloy surface.
