Abstract Scope This work considers the preparation of a zinc coating doped with aluminum under conditions of self-propagating high-temperature synthesis (SHS) for automobile parts. In order to increase the corrosion resistance of sheet steel used in the automotive industry, zinc coatings were doped with aluminum at temperatures of 550-650 C. When galvanizing under SHS conditions, δ1, G phases, Fe2Al5 and FeAl3 are formed. An analysis of the microstructures showed that the zinc coating forms uniformly. With increasing strip thickness and temperature, the amount of aluminum in the layer increases. Coating adhesion is also increasing. Galvanizing a steel strip under SHS conditions helps to obtain a high-quality diffusion coating on its surface. Hardening of the surface layers of carbon steels allows one-and two-phase zinc coatings alloyed with chromium with a corrosion resistance of 37-53% to be obtained more than after galvanizing by the galvanic method.
