等离子喷涂成形（PSF）由于热源温度高、焰流速度快，非常适合高熔点高硬度材料的近净成形，近年来得到广泛关注和发展。文章综述了PSF技术中的喷涂粉末制备、芯模制备和处理、喷涂过程和后处理四个方面的研究现状，详细介绍了PSF技术在制备薄壁零部件、快速模具和某些特征材料方面的应用进展。在PSF研究领域，各国更多地注重应用研究，在其基础理论方面有所欠缺，还没有形成一套公认的理论体系；后续研究应在进一步分析粉末熔融、飞行和撞击各阶段的现象和数据基础上，深入探究喷涂过程的物理本质，综合考虑制粉、芯模和后处理等工序，以求建立一套喷涂参数-制件性能关系理论，用以指导PSF实践。

Plasma Spray Forming, due to its characteristics of high source temperature and fast flow flame, is suitable for the near-net-forming for the refractory material with high hardness. This paper reviews the research status in the four aspects of PSF technology, including spray powder preparation techniques, preparation and processing of the mandrel, the coating process and post-processing. The application advances of thin-walled parts preparation, rapid tooling and some characterized materials are introduced. An accepted theoretical system in the field of PSF has not been established for most researchers have focused on the application, rather than the basic theory. It has not accepted the formation of a theoretical system. Milling, mandrel and post-treatment processes taken into account, the spray parameters-Part Performances Relations Theory should be established by exploring the physical nature of the coating process based on analyzing the phenomenon and data of the powder melted, the various stages of flight and impact.
