摘　　要：纳米结构涂层因具有良好的耐磨性、耐高温、光催化活性及仿生性能等性能,在材料表面改性方面具有重要的应用价值。冷喷涂作为一种低温沉积技术可避免晶粒粗化,保持纳米结构涂层的特性。概述了冷喷涂的工作原理及沉积机理,介绍了影响冷喷涂沉积纳米结构涂层的主要工艺参数和冷喷涂辅助技术;分别从热障涂层、耐磨涂层、光催化涂层、仿生涂层方面阐述了冷喷涂沉积纳米结构涂层的研究进展。并对冷喷涂纳米结构涂层的发展前景进行了展望。Nano-structured coating has excellent properties of wear resistance, high temperature resistance, photocatalytic activity and biomimetic performance, and it has important application value in material surface modification. The cold spraying technology can avoid grain coarsening in nano-structured coating due to low temperature deposition, which can keep the properties of nano-structured coating. The working principle and deposition mechanism of the cold spraying were introduced. The main process parameters which affect the cold spraying nano-structured coating were introduced and the cold spraying assisted technology was also introduced. The research progress of cold sprayed nano-structured coatings were discussed from thermal barrier coating, wear-resistant coating, photocatalytic coating and biomimetic coating. The developing prospect of cold sprayed nano-structured coating was looked forward.
