FIELD: application of coating by method of electrical arc metallization of protecting corrosion-resistant and wear-resistant layers on working surfaces of pieces. SUBSTANCE: method of electrical arc metallization provides for melting by electrical arc of spraying material and its transfer in fine melted form by compressed air stream on spraying surface. In the case transfer of spraying material is exercised by pulses, that are produced by pressure difference. EFFECT: improved process of metallization. 1 dwg, 1 tbl
