We proposed a new method of protecting copper and steel from atmospheric corrosion based on short-term treatment of metals with vapors of low volatile compounds at elevated temperature. A complex of corrosion and optical methods has shown that the treatment of copper and steel samples at elevated temperature by a suitable chamber inhibitor leads to the formation of the finest hydrophobic films on the surface of metals that have a long aftereffect and effectively
protect the metal from atmospheric corrosion.
