| 中文摘要: |
| 从冷喷涂粒子速度与温度协同问题出发，归纳总结了影响冷喷涂涂层质量的主要因素，并在此基础上，重点综述了喷嘴结构、气体类型与性质、粒子形态与材料等工艺参数与粒子速度-温度的作用关系。提高喷枪喷嘴扩张段膨胀比，改善黏性效应，提高高速区面积，使用高热扩散系数材料的喷嘴，均能够显著改善粒子速度-温度的协同效果。在工业应用中，可采用喷丸辅助冷喷涂、激光辅助冷喷涂、静电辅助冷喷涂、真空冷喷涂等新型复合沉积技术，实现高强低塑性喷涂粒子材料的沉积成形。最后，就如何深入研究速度-温度高质量协同并获得高质量涂层进行了展望。 |
| 英文摘要: |
| 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. |
