Research Progress of Cold Sprayed Cu - Based Alloy Coatings

Abstract

In this work, the status of preparing Cu - based alloy coatings by cold spraying in recent years was systematically introduced. The techniques adopted for the cold spraying of bronze, Cu - Zn and Cu - Cr and other types of Cu - based alloy coatings were summarized, and the properties of coatings were represented from the aspects of microstructure, mechanical properties, wear resistance and corrosion resistance. At last, the future research and development direction of the cold spray technology in relation with Cu - based alloy coatings was prospected.
