Abstract

Ellipsometry has been used to study the influence of Benzylamine, Benzotriazole and Hexamethylenetetramine on the growth of anodic oxides on iron and on AISI 304 stainless steel in borate‐buffer solutions.

On iron, a limitation of the growth‐rate has been observed for these substances all over the passive potential range. On AISI 304 steel, when the electrode potential exceeds 400 mV (SCE), an increase of the anodic oxide growth‐rate was found in the presence of the organic substances. Adsorption on the oxide film, according to the interpretation given by Pearson, is discussed.
