The article presents the results of studies of the effect of flux components on the adhesive strength, porosity and oil absorption of coatings obtained by supersonic arc metallization (EM) using aerosol fluxing (AF) deposited on 45G2 steel with a speed v = 400-410 m / s. Due to the use of AF in EM, the adhesion strength of electrometallization coatings (EM coatings) increases. The highest value of adhesive strength is 66 MPa. Porosity due to the use of AF decreases by 1.5 - 1.6 times, in comparison with EM coatings without AF. At the same time, the oil absorption of EM coatings using AF decreases 1.6–1.7 times. It is advisable to use EM coatings with AF when restoring worn-out parts for various purpose equipment, as well as for eliminating defects at the production stage.
