Aluminum Alloy Corrosion Inhibition with a Composition of Guar Gum and Potassium Sorbate.

High efficiency of corrosion inhibition of aluminum alloy in a 0.1% NaCl solution with a composition of guar gum and potassium sorbate was established. The formation of an organic adsorption film was found on the surface of the metal samples. The degree of metal protection against corrosion by this inhibitory composition was more than 90%. The results of the research can be used for the development of eco-friendly "green" corrosion inhibitors of aluminum alloys from renewable plant materials. [ABSTRACT FROM AUTHOR]
