D'ELIA, L.F.; TORRES, F.  y  BAEZ, V.. Voltammetric Adsorption Studies of Commercial Corrosion Inhibitors. A First Correlating Approach to the Corrosion Inhibition Efficiency. Port. Electrochim. Acta [online]. 2009, vol.27, n.6, pp.671-680. ISSN 0872-1904.

Adsorption of film forming corrosion inhibitors on metallic surfaces led to a decrease in corrosion rates, since the adsorbed organic molecules behave as chemical and physical barriers for cathodic and anodic reactions. A novel and simple methodology to characterize commercial corrosion inhibitors is proposed. Fundamental studies of film forming corrosion inhibitors adsorption on platinum and its correlation with corrosion inhibition efficiencies of steel provide useful information for quality control of film forming inhibitors.

Palabras clave : corrosion inhibitors adsorption; corrosion inhibition; impedance spectroscopy; cycle voltammetry; adsorption-corrosion inhibition correlation.
