Applications Catalytic Coating Production Method. The invention relates to methods for producing catalytic coatings by thermally spraying a powder material and can be used in different branches of chemistry, in power engineering, and in automobile production. The aim of the invention is to obtain a catalytic doublesided coating on a metal strip, which, apart from high catalytic properties in nitrogen oxides reduction and hydrocarbon oxidation reactions, exhibits high mechanical and operating properties, namely a high adhesion to a metal substrate and a high resistance to contamination in the atmosphere of sulfur dioxide gases and water vapor. For this purpose, the inventive method for thermally spraying a powder material to a metal strip consists of using a special composite powder that comprises an aluminum metal core, an intermediate aluminum hydroxide layer, and a cobalt hydrotalcite coating on a particle surface, which is applied to the intermediate layer. The qualitative and quantitative compositions of the composite powder are also disclosed. The inventive catalytic coating is sprayed according to a method consisting of thermally spraying to a metal strip, mechanically processing said strip, and forming an article. WO2008063038: A.P.
