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 subse-quent 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 electro-chemical 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
