A real-time and realistic computation on the entire cold gas dynamic spray process has been carried out by the integrated model of flow considering shock wave, splat formation, and coating formation. The in-flight behavior of nano/micro particle in the supersonic jet impinging on the substrate with a cavity, and also the interaction between a particle and shockwave has been made clear from this study. By clarifying the effect of cavity shapes on a coating formation inside the cavity, optimum cavity shape was proposed for cavity filling process. Then, the fundamental data has been provided for the advanced application of a high performance cold gas dynamic spray process to a dental treatment or structural repair.
