FIELD: various technological processes.
SUBSTANCE: invention relates to a method of forming a nickel-aluminium corrosion-resistant coating on steels. Diffusion saturation of the article is carried out at temperature of 900–1,070 °C for 2–5 hours in a melt containing components at the following ratio, wt.%: lead 89–97.5, lithium 0.5–1, nickel 1–5, aluminium 1–5.
EFFECT: increasing the corrosion resistance of steel products under the aggressive influence of a hydrogen sulphide-containing working environment on them.
