Metal-Ceramic and Epoxy Composite Materials Nanostructure Coatings

One of the ways to increase the reliability of various products is the use of protective coatings. As for now scientific and technical developments offer various methods and ways of applying and forming multipurpose functional coatings. They include various composition materials gas flame spraying. Nowadays the method of cumulative-detonation multi-chamber high-speed spraying of metal powders, their oxides, nitrides, carbides, etc., has been actively developed and implemented. The advantages of this method include the high strength of adhesive joints to the base, the nanostructures formation, and the possibility of the formation of phases with different types in coating material. Metal details protective properties are improved. The combination of metal-ceramic and polymer coatings will expand a functional range of their potential use. Gradient multilayer coatings based on aluminum oxide and epoxy composite are proposed. The first adhesive layer is sprayed with a thickness of 100–150 microns from aluminum oxide (Al

) with a dispersion of 5–15 microns. Aluminum oxide is more preferable when applied to an aluminum base. Such a layer has high electrical breakdown strength, thermal conductivity and adhesive strength due to the crystalline compatibility between the aluminum base and the material of the sprayed layer. In addition, nanostructured formations appear in the coating material during spraying. It gives a wide range of required coatings operational characteristics. This will provide the coating with a set of operational characteristics.
