In this study, the influence of particle type and substrate hardness on the deposition behavior of single WC-17Co particle during the cold spraying process was investigated. The morphology of the deposited particles was examined by scanning electron microscopy (SEM) from the particle surface and cross-sections. It was found that with increasing substrate hardness, the deposition behavior of WC-17Co particles transformed from completely embedding into soft substrate to partially flattening and even rebounding from the hard substrate. In the comparison between different powder types, spherical nanostructured WC-17Co particles experienced the more intensive deformation due to the smaller WC size.
