Abstract: The effect of AC-induced voltages on corrosion systems was investigated. Two cases were distinguished: the anodic and cathodic reactions were under activation control, the anodic reaction was under activation control and the cathodic reaction was under mixed control. For the first case simple relations could be derived that relate the AC-induced voltage with the corrosion potential and corrosion rate. For the second case numerical analysis was necessary to obtain these relations. It was shown that the influence of the AC-induced voltages on the corrosion behaviour strongly depended on the Tafel parameters. As the cathodic reaction was under mixed control the increase of the corrosion rate was limited to the diffusion-limited current density. (C) 1998 Published by Elsevier Science Ltd.
