Composition Design and Laser Cladding of Cu-Zr-Al Alloy Coating on the Magnesium Alloy

Abstract:

The cluster line criterion was used for optimized design of a Cu-Zr-Al alloy used as coating on the AZ91HP magnesium alloy by laser cladding. Results show that the coating mainly consists of an amorphous, Cu8Zr3, and Cu10Zr7 phases, of which the relative content of amorphous phase is estimated to be 61 %. The formation of the amorphous and intermetallics composite structure results in high hardness, good wear resistance and corrosion resistance. The interface between the clad layer and the substrate has good metallurgical bond.
