FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used for metallisation of parts and their recovery. Electric arc metalizer includes housing, spraying head with cylindrical nozzle and air ducts and electrode wires in current-conducting tubes with tips connected to current conductors and mechanism of their movement. Outer side of cylindrical housing is made of metal with low specific weight and is coated with protective ceramic layer. Front wall of spray head is made with channels and holes connected with central nozzle, inner part of which is composite with cylindrical and conical parts. Cylindrical part is made with through hole with diameter of 0.8 mm at distance not exceeding 10 mm from its end and beginning of conical part. Ratio of diameters of inlet and outlet sections of conical part of nozzle is 1.8–2.0.
EFFECT: technical result of the invention is to improve the quality of coating, increase rate of its application and high efficiency of the process.
