The corrosion inhibition of copper by benzimidazole


The chemical nature of the complexes formed between copper and benzimidazole in solution has been determined with the aid of Auger electron spectroscopy. Measurements of the adsorption isotherm of benzimidazole on copper reveal that such adsorption is of the Langmuir type. Some correlation is seen to exist between the corrosion inhibition tendency of benzimidazole on copper and the composition of the surface films formed. © 1982.
