FIELD: steel enamel coating, in particular surface treatment of steel products before direct-on enamel coating.
SUBSTANCE: claimed method includes nickel film plating and additional copper film plating. Method of present invention makes it possible to avoid insufficient purity of deposited metal, coat embrittlement, insufficient enamel adhesive strength with steel surface, and is useful in manufacturing of enameled steel articles of various applications and multiply configuration.
EFFECT: method characterized by conventional metal treatment, decreased reagent consumption; coating of improves mechanical properties.
