Studies on Plant Materials as Corrosion Inhibitors

Abstract

AbstractAbstractVarious parts of several plants were tested for their performance in protecting steel and aluminium against corrosion under immersed conditions. Argemone mexicana, calotropis procera, carrot and garlic were found to be good inhibitors for steel in neutral media, while tobacco, black pepper, castor seed, acacia gum and lignin proved to be good inhibitors for steel in acid media. For aluminium in acid medium, tobacco, lignin and black pepper were effective inhibitors.
