Protection of copper by treatment with hot vapors of octadecylamine, 1,2,3-benzotriazole, and their mixtures

摘要

The possibility of creating an effective technology for protecting copper products by treatment with vapors of low-volatile corrosion inhibitors at elevated temperatures is demonstrated for the first time. It is shown that 1-h treatment with vapors of octadecylamine or its mixture with 1,2,3-benzotriazole at t = 100 degrees C results in the formation of ultra-thin hydrophobic adsorption films, markedly increases the corrosion resistance of copper, and can be used for temporary protection of metal products.
