摘要:
冷喷涂技术因其固态沉积特性及突出的冶金优势,在金属或金属基复合材料涂层制备、增材制造与修复再制造等领域获得了国内外研究者的广泛关注。 近十年来,国内外对冷喷涂技术的基础理论研究也取得了重要进展。 冷喷涂粒子加速加热行为是结合机理研究的先决条件。 因此,文中结合作者多年的研究经验,对冷喷涂过程中气固两相流动行为及喷涂工艺优化的最新进展进行了综述。 首先,分析了冷喷涂喷嘴内外的气体流动特性;其次,讨论了冷喷涂粒子的加速与加热行为;然后,阐述了冷喷涂过程中工艺参数优化的策略;最后,给出了相关研究的发展方向。

Abstract:
Cold spray has been applied in producing metals or metal matrix composites coatings, additive manufacturing and repairing of components due to its solid-state deposition nature and prominent metallurgical advantages and has been attracting more and more scholars and entrepreneurs around the world in recent years. In the last ten years, great progess has been made on the theoretical study of bonding mechanisms in cold spray. The acceleration behavior of particles during cold spray is an im- portant prerequisite for understanding the bonding mechanisms. Therefore, in this paper, the state-of-the-art of gas-solid two- phase flow behavior during cold spray and process parameters optimization were summarized by referring to the relevant research results in recent ten years and the experience of the authors. Firstly, the aerodynamic characteristics inside and outside the cold spray nozzle were analyzed. Secondly, the acceleration and heating behaviors of cold spray particles were discussed. And then, the optimization strategy of process parameters in cold spray was introduced. Finally, the research perspective was given.
Key words:  cold spray  particle  gas-solid two-phase flow  process parameters  numerical simulation
