FIELD: machine building.
SUBSTANCE: invention relates to machine building, namely, to galvanic coatings producing methods with subsequent thermal treatment for corrosion protection of steel items. Method involves successive zinc layer electrolytic application on part, and then tin layer with subsequent thermal treatment of part, wherein on said tin layer zinc layer or zinc layer and subsequent tin layer are additionally applied, and part heat treatment is carried out in single stage at temperature of not less than for 18.5 °C below than zinc and tin eutectic melting temperature.
EFFECT: technical result is improvement of coating protective ability and prevention of corrosion products formation.
