Since cold spraying (CS) technology was discovered, it has shown prominent potential in fabricating compact metallic coatings. However, the coating performance cannot meet the needs of the industry in some cases. For this, in this article, with taking copper as an example, the technology and performance characteristics of cold sprayed copper coatings at home and abroad in recent years were reviewed. The effects of four post - treatment processes on the microstructure and properties of cold sprayed copper coatings were discussed, and the applications of cold sprayed copper coatings in main fields were given. Finally, the problems and solutions still existing in the preparation of copper by cold spraying were analyzed and prospected.
