Abstract:Results of studies in the adsorption of carboxylic-acid salts (diftorant, mephenamic acid, fluphenamic acid and its compositions with benzotriazole) at iron and low-carbon steel surfaces from neutral borate buffer solution are presented. A link between adsorption and protective ability of these compounds is revealed. Anticorrosion protection of metals can be improved by formation of bi- or even multilayer nanocoatings of inhibitors in aqueous solutions or vapor phase.
