As a solid-state deposition technique, the main problem with cold spraying additive manufacturing (CSAM) is the poor ductility of sprayed depositions. Subsequent heat treatment can effectively solve this problem,related researches involved Cu, Zn, Al, aluminum alloy, Ti, Ti6Al4V and low carbon stainless steel coatingsproduced by cold spraying. This paper summarizes the effects of heat treatment on the electrical resistivity,corrosion resistance and mechanical properties of cold sprayed coatings, so as to provide guidance for application of heat treatment in cold spraying additive manufacturing.
