In this paper, we developed the conditions for the deposition of zirconium oxide coatings from solutions containing hexafluorozirconic acid, nickel and molybdenum salts on a steel base. Optimal concentrations of nickel and molybdenum were determined to obtain oxide-zirconium coatings used as adsorption layers for paint coatings. The effect of temperature, time and subsequent heat treatment on the protective anticorrosive and adhesive characteristics of oxide-zirconium coatings has been established. It is shown that the formed oxide-zirconium coating are Nano scale size. It is established that the corrosion resistance of the investigated coatings in the temperature range 30-40°C is in agreement with their adhesion strength. On the basis of electrochemical studies, it was shown that the addition of hexafluorozirconic acid to nickel and molybdenum salts leads to inhibition of iron ionization and an increase in the corrosion resistance of the formed coating.
