The integrated model of thermofluid, splat formation and coating formation for an advanced cold spray process has been established. The in-flight behavior of micro-nano particles, the interaction between shock wave and particles in a supersonic jet impinging onto the substrate are clarified. Then, the advancement of cold spray process by electrostatic particle acceleration and the effect of activated coating surface has been discussed in detail by carrying out a real-time computational simulation. Finally, based on this integrated model, coating thickness in a cold spray process is evaluated.
