Abstract

The electrochemical behaviour of thin film metallic iron and the iron oxides in 1 M KOH anaerobic aqueous solution was studied by cyclic voltammetry technique. The material studied was of thin film (50 nm) iron supported on a glass substrate, and the oxide thermally formed on the iron film. The voltammetry of thin film iron on glass was similar to that of low carbon steel and gave a convenient means for preparing specimens for obtaining information relevant to the degradation of structural steel. In this report, the formation of various types of oxides on the iron surface are identified, and the electrochemical stability of the oxides and their relevance to the cathodic disbonding of organic coating from cathodically protected steel pipelines are discussed.
