Multipurpose protective coatings on metallic and carbon base materials

This monograph deals with the problems of forming protective coatings on the surface of articles made from steels, refractory metals and carbon-carbon materials. The protective coatings are produced using the ecologically clean method of vacuum activated diffusion saturation. The method provides deposition of homogeneous protective coatings uniformly distributed on the surface of complex pieces having small cavities and pin holes. The monograph describes in detail the methods of high-temperature silicide coating formation on molybdenum, tungsten and niobium and considers the mechanism of coating behavior under the oxidizing medium attack. The conception of the high-temperature coating production on carbon-carbon materials is presented. The protective coatings on these materials are formed by the method of vacuum activated diffusion saturation under the simultaneous attack of gaseous and liquid media accompanied by the self-propagating high-temperature synthesis.
