In order to explore the feasibility of cold spraying as method to prepare Cu-Cr composite, the deposition behavior was analyzed. The results show that particles parameters, such as morphology, size distribution and deformability, result in different deposition behavior. For Cu, since plastic deformation easily occurs, when a Cu particle impacts Cu substrate, both particle and substrate at the interface undergo extensive deformation, resulting in the greater bond probability. Although the velocity of Cr is higher than that of Cu, Cr particles have lower bond probability because of its hardness and fragility. Cr particles are embedded in the Cu particles. The properties of Cu-15%Cr meet industrial standard, superior to the composite prepared by explosive compaction. The results reveal cold spraying can be considered as a suitable technology for Cu-Cr composite.
