Cold spray is the solid-state process for elaboration of metal coatings and free-standing parts. The absence of material melting during build-up of deposit allows to apply this technology for producing metal composites with innovative properties. The cold spray metal composites could be produced by deposition of composite powders or by simultaneous spraying of powder mixtures. The second approach is considered as the most robust and the simplest one that is important for industrial application. In the present paper, the comprehensive review of the actual knowledge about the formation of metal composite by simultaneous cold spraying of several powders is performed. The main advantages of this approach as well as the issues and the limits are analyzed. The eventual applications of the cold spray composite deposits are also discussed.

冷喷涂是用于精加工金属涂层和独立零件的固态工艺。在沉积物堆积过程中不会发生材料熔化，因此可以将该技术应用于生产具有创新性能的金属复合材料。冷喷涂金属复合材料可以通过沉积复合粉末或同时喷涂粉末混合物来生产。第二种方法被认为是对于工业应用最重要的最健壮和最简单的方法。在本文中，对通过同时冷喷涂几种粉末形成金属复合材料的实际知识进行了全面回顾。分析了这种方法的主要优点以及问题和局限性。还讨论了冷喷涂复合物沉积物的最终应用。
