The data on corrosion of Mk.3 steel with different coatings in atmospheric air containing potassium chloride, hydrogen chloride and sulfur dioxide impurities below the maximum permissible concentrations have been analyzed. A linear dependence between hydrophobic behavior and protective properties of coatings applied on steel was revealed both for standard compositions and for compositions with nanostructured filler (1 wt. %) obtained by hydride solid-phase synthesis.
