FIELD: metallurgy. ^ SUBSTANCE: invention relates to mechanical engineering field, chemical, metallurgical and other industries. Particularly it relates to anodic immunization of low-alloy steel. Method includes heating, anodic polarisation in salt melt and aftercooling with preliminary building of anodic polarisation curve for low-alloy steel in saline melt at the temperature 350 - 550 C and by its mean it is defined immunization potential of low-alloy steel, and anodic polarisation is implemented at the temperature 350 - 550 C during 1.0 - 1.5 hours at potentials, increasing steel immunization potential per 0.25 - 0.40 V. ^ EFFECT: increasing of thickness surface protective layer, enriched by alloying elements. ^ 1 dwg, 2 tbl |
