Abstract

L'invention concerne des procédés de fabrication d'un revêtement par la pulvérisation d'un matériau en fusion et peut s'utiliser dans de diverses branches de l'industrie chimique, de la production d'énergie, du génie mécanique et de la métallurgie. Le revêtement composite fabriqué selon ce procédé peut s'utiliser en tant que substrat destiné à l'application de divers revêtements, par exemples, de revêtements polymères, et dans l'imprégnation par de diverses compositions, y compris les compositions catalytiques. Elle vise à produire un revêtement présentant de meilleures caractéristiques techniques et d'utilisation telles que l'adhérence et les dimensions de la surface libre que les revêtements existants, ce qui permet d'obtenir un revêtement ayant une meilleure qualité et une meilleure fiabilité. L'invention vise également une technologie plus simple et efficace d'application de revêtements. A cet effet, on introduit dans la composition un matériau assurant le développement d'une microstructure de revêtement, une poudre composite comportant un revêtement de type d'hydrotalcite. L'invention porte aussi sur la teneur qualitative et quantitative de la composition. Le revêtement ayant la composition décrite dans l'invention est pulvérisée sur la surface métallique ou céramique, et on effectue le traitement thermique par recuit. L'invention concerne aussi un procédé de traitement thermique et des régimes dudit traitement.
