The research of tribological logic characteristics of electric arc coatings from powdered wires in technological environments was conducted: under conditions of limit lubrication in lubrication I-20;
in the environment of 3 % emulsor of the brand Hydroway 1060 and lubrication M10V2. Coatings in the thickness of 1.2–1.5 mm were applied by serial electro-arc metal with the inhibitor of PMI-1

The peculiarities of coating formation by the gas-thermal method at application of powder wires are considered. This is due to the presence of pores and solid inclusions in the resulting layer. Therefore, it is important to investigate the influence of the mechanical processing parameters and the composition of the powder wire on the roughness of the polished surface of the electric arc coatings. Coatings in the thickness of 1.2 ... 1.5 mm were applied with a serial electro-arc metalizer EM-14 on a pre-treated surface of both flat and cylindrical specimens.
