Abstract
The process of plasma spraying, structure and properties of coatings from composite powders "ferrovanadium-boron carbide" are considered. Analysis of phase composition of the coatings and powder particles that have passed through the plasma jet shows that reaction of exothermic interaction of components to form vanadium and iron borides and carbides takes place during the spraying process. Microhardness of the coatings amounts to 16,930-18,920 MPa.
Keywords: plasma-arc spraying, composite powders, ferrovanadium, boron carbide, synthesis, phases, exothermic reaction, dispersed-strengthened structure
