FIELD: mechanical engineering. SUBSTANCE: powder filler material is fed into tail part of melting bath by means of gas jet. Arc vibrational motion is applied to gas-powder jet, which arc coincides with optimal isotherm of liquid metal of the bath. Facing is carried out by electric arc with electrode vibrations. Metal faced is doped or forced uniformly due to uniform distribution of physical-mechanical properties of coating faced. EFFECT: improved uniformity.
