FIELD: technique of high-temperature spraying of powder coatings. SUBSTANCE: burner for flame spraying of powder coatings additionally has two removable devices with vessels and gates for supply of powder and with injectors for carrying gas. In this case, all three removable devices are secured to E-shaped intermediate member in which interconnected channels for powder supply are accommodated. Using of the invention makes it possible to considerably increase quality of sprayed coatings due to producing composite layers different in properties and to increase spraying process efficiency due to simultaneous supply into channel of gas-powder mixture of various powders from three vessels of powder supply device. EFFECT: extended process potentialities of burner; high efficiency of process of multilayer spraying by preliminarily set conditions according to type of powder materials and requirements to sprayed layer. 8 dwg
