摘要:: 随着各行业对于零器件的精细化程度要求越来越高，传统的锻造和铸造等成型技术已不能满足生活生产的需求，冷喷涂作为一种新兴的增材制造技术，因其沉积过程中无相变、无氧化且沉积效率高等特点而受到广泛关注。本文首先阐述了冷喷涂技术的基本原理及其在材料制造方面的优势；随后，综述了冷喷涂在金属、金属基复合材料及层状复合板材制备领域的国内外进展；最后总结了目前冷喷涂技术所面临的问题及亟需突破的壁垒，并针对现存问题提出了新的研究目标和发展方向。

Abstract:: With the increasingly high requirements for the degree of refinement of parts in all walks of life, the traditional forging, casting and other forming technologies can no longer meet the needs of life and production. As an emerging additive manufacturing technology, cold spraying has attracted widespread attentions because of its unique characteristics of no phase change, no oxidation and high deposition efficiency in the material preparation process. In this paper, the basic principle of cold spray technology and its advantages in additive manufacturing are described. Then the progress of cold spraying in the preparation of metals, metal matrix composites and laminated composites at home and abroad is reviewed. In the end, the current problems and barriers that need to be broken through faced by cold spraying technology are summarized, and in view of the existing problems, new research objectives and development directions are proposed.
