Abstract
The effect of hot vapors of an octadecylamine–benzotriazole mixture on the corrosion resistance of monolithic copper and electroplated copper coating was studied. It was found that the inhibitor efficiently suppresses the initiation of corrosion of both materials in fog spray. Optimal conditions for chamber treatment of copper are 20 min at 150°C. This mode enables the formation of a stable protective film without disturbing the decorative properties of the surface. It was shown that mixture inhibitor forms films on the copper surface, which reduce the active metal surface area and stabilize its passive state.
