Known methods of production of composite powders have a series of deficiencies. The method of self-propagating high-temperature synthesis which has appeared recently has conclusive advantages. The method allows forming in a single work cycle micro and a macrostructure of a composite particle. The present work is devoted to viewing of questions targeted mechanical activated synthesis of composite powders for thermal spraying of function coating of various applications. Results of synthesis of powders Ti and Cr carbides in oxygen atmosphere are given.
