Deposition efficiency optimization in cold spraying of metal-ceramic powder mixtures

Reporter: Klinkov S.V.

In the paper, results of optimization of cold spraying process of mixtures of metal and ceramic powders are presented. In the optimization study, a two-probability model was used to take into account coating surface activation induced by ceramic particle impacts. Dependence of mixture deposition efficiency upon concentration and size of ceramic particles was analyzed. Dependences of optomum size and concentration of ceramic particles, as well as gain in mixture deposition efficiency upon adhesion probability of metal particles on non-activated surface were obtained.
