Abstract
Cold spraying is a new coating technique that makes a thin layer on the solid surface of various mechanical components using tiny material particles. Differing from the conventional thermal spraying methods, there are some advantages for example, oxidation and thermal deformation of the target substrate is unlikely to occur. While the fundamental researches and applications of a cold spraying have been carried out, deposition phenomena in cold spray has not been fully clarified yet. In this paper, numerical simulations on the first step of the film forming process are conducted by a MPS (Moving Particle Semi-implicit) method. Thereby, the numerical result of the height of the particle deposition is well accord with the experiment. The characteristic phenomena is reasonably reproduced. That is, an impinging particle whose speed is lower than the critical velocity rebounds from the substrate, meanwhile, an impinging particle whose speed is higher than the critical velocity adheres on the substrate.
