Abstract
Corrosion of steel 3 and steel 3 with different coatings in air atmosphere containing impurities of HCl, SO2, KCl (0,04-0,20 mg/m3 , humidity 70-100%) in model conditions by gravimetric method has been investigated. The symbatic dependence between water-repellent properties of coatings and their protective properties has been established. The possibility of fine regulation and increase of protective properties of coatings by using nanofilms of oncationic tensides, base of silicone-organic compounds and nanostructured hydrophobic Si-C-containing fillers in the composition of coatings is shown.
