FIELD: methods of producing composite materials and coats made from these materials. SUBSTANCE: powder component is fed individual flow of transporting gas received from delivery unit which is connected with system of shut-off and control equipment used for control of delivery of gas- and-powder suspension. Transporting gas regulated to required parameters is fed to system regulating the concentration of powder components in flow of gas powder components are fed from unit made in form of several feeders-proportioners. Gas suspension thus obtained is admitted to inlet multi-passage pipe union and multi- passage branch pipe wherefrom it flows via passages with bevel multi-passage branch pipe wherefrom it flows via passages with bevel cut to area of elongated portion of throat section of accelerating supersonic nozzle to core of flow of accelerating carrier gas formed by means of compressed carrier gas delivery unit. Particles of powder components are intensively mixed and accelerated in elongated portion of nozzle throat section to velocities close to transonic. At gasdynamic action of gas-and-powder flow accelerated in nozzle on substrate, chemical interaction of powder components of exothermic composition is initiated; as a result, composite material is obtained which may be separated from substrate or may be retained in coat. EFFECT: extended functional capabilities of gas-dynamic method due to obtaining composite materials from powder compositions entering the reaction of high-temperature self-propagating synthesis. 11 cl, 2 dwg
