| Abstract: |
| Based on the synergy between the velocity and temperature of cold-sprayed particle, this paper summarized the main influencing factors for the quality of cold sprayed coatings. And on this basis, the correlations were discussed between process parameters (such as nozzle structure, gas type and property, particle morphology and materials) and velocity and temperature of particle. It is widely accepted that increasing the expansion ratio of the spray nozzle, improving the viscosity effect, increasing the area of the high-speed zone and using a nozzle with a high thermal diffusion coefficient material can significantly improve the synergy effect of the particle velocity and temperature. From the view of industrial application, some new composite deposition processes such as shot peening assisted cold spraying, laser assisted cold spraying, electrostatic assisted cold spraying, and vacuum cold spraying can be used to realize the deposition modeling of high-strength but low plasticity sprayed particle materials. Finally, the prospect was put forward about how to further study the high-quality synergy between the velocity and temperature of particle and thus obtain high-quality coatings. |
