Abstract Scope This scientific work describes the study of the production of zinc coatings on sheet steels during their processing in zinc SHS mixtures. Galvanization in SHS - mixtures is a combination of gas-phase and liquid processes. To reduce the oxidation of SHS - blends, small amounts of aluminum and silicon were introduced into their composition. Alloying zinc coatings with aluminum and silicon contributes to the production of high-quality coatings with high reflectivity and adhesion. Zinc SHS - charge containing additives of aluminum and silicon is less oxidized, since a protective film of SiO2, Al2O3 is formed on its surface, which, interacting with the main components of SHS - charge, forms spinel compounds, protecting SHS - charge from oxidation. The microhardness of zinc coatings was 3800-5300 MPa. With an increase in the galvanizing temperature, the hardness of the layer increases to 5900 MPa, which corresponds to the microhardness of the δ1 phase.
