FIELD: metallurgy.
SUBSTANCE: device comprises chamber, powder feed system composed of two bins secured at chamber top section by powder ducts, two discs with loading channels rigidly secured at DC motor armatures. Angle between disc rotation plane and mirror axis of powder feeder makes 30-45 degrees to allow good fluidity and quality of fed powder mix. Chamber accommodates the union for feed transfer gas and powder mix and transfer gas feed nozzle.
EFFECT: mixing of two powders for surfacing at adequate ratio.
