Advanced Functional Metal-Ceramic and Ceramic Coatings Deposited by Low-Pressure Cold Spraying: A Review

Based on the recent analysis of various databases, cold spray (CS), newest method among thermal spraying technologies, has received unabated attention hundreds researchers continuously since its invention in 1980s. The significance CS lies low process temperature, which usually ensures compressive residual stresses and allows for formation coatings a thermally sensitive substrate. This paper concerns low-pressure (LPCS) variant employed forming metal matrix composites (MMCs) with high ceramic contents all-ceramic coatings. At very beginning, influence LPCS parameters deposition efficiency (DE) is analysed. In next part, most useful feedstock powder preparation techniques LCPS are presented. Due to combination bottom-up production methods (e.g., sol-gel (SG)) LCPS, that works as binder particles MMC can be removed, resulting Furthermore, optimization parameters, it possible predict control phase transformation material. Further paper, differences bonding mechanism metal–ceramic mixtures properties applications also discussed. Finally, exemplary direction development suggested.
