FIELD: metallurgy.
SUBSTANCE: thermodiffusion zinc coating on surface of a steel product contains in-series located iron-zinc layers of alpha-, gamma- and delta-phases. With that, on surface of layer of delta-phase, the coating contains iron-zinc layer with thickness of 1 mcm to 20 mcm with orthorhombic structure and with iron content of 5-7 wt %.
EFFECT: improving corrosion resistance of the products.
