A critical velocity was accepted as characterizing the kinetic spraying (or cold gas dynamic spraying), which works by accelerating small solid particles to supersonic velocity and impacting them onto the substrate. However, there was lack of the information about individual particle impact and deposition behaviors with a large range of impact velocity. To probe into particle impact behaviors and approach the deposition mechanism, individual particle impact tests have been carried out. A rebound phenomenon that a high fraction of rebounded particles occurred at a high impact velocity was found. Based on experimental results, a model of a plastic particle impacting onto an undeformed substrate was built up. The adhesion and rebound energy were calculated to estimate the particle/substrate interaction. A maximum impact velocity was found for the particle deposition onto the substrate. The particle deposition behavior was controlled by the adhesion and rebound energy.
