Description: This animation demonstrates construction of the polarisation plots for anodic and cathosic reactions. However, in practice it is very difficult to measure the anodic and cathodic curve of the given reaction independently. Normally the polarisation curve of the total system is measured giving directly (and only) the total current. Fortunately the corrosion potential and corrosion rate can then still be determined.
Keywords: polarisation plot • anodic reaction • cathodic reaction • corrosion rate • corrosion potential
