FIELD: technological processes; metallurgy.SUBSTANCE: invention relates to electroplating and can be used for application of protective coating on items made of low-carbon steel, which can be operated at high temperatures. Method involves electrolysis of halide aluminium-containing melt using aluminium anode, wherein coating is applied by electrolysis of salt melt based on AlFwith additives NaF and/or KF at temperature of 700-980 °C, current density of not less than 0.5 A/cmand use of aluminium melt as anode.EFFECT: obtaining solid aluminide coating having good adhesion to steel substrate, higher content of aluminium in coating, higher heat resistance of steel items and rate of aluminising.1 cl, 1 tbl, 2 dwg |
