| Research Abstract |
In this study, the integrated model of particulate supersonic flow and coating formation for cold gas dynamic spray process is established. It was shown that electrostatic particle acceleration enhances the coating performance even under the presence of shockwave. Furthermore, the optimum cavity configuration was obtained by clarifying the influence of cavity configuration on coating formation. The fundamental data was obtained from this study for the advanced applications of cold as dynamic spray process.
