Bandy, R.; van Rooyen, D.

Use of the two-electrode method for determining corrosion rates and Tafel constants is described. The method involves polarization resistance measurements, as well as polarization data further from the corrosion potential. Combined treatment of these data enables the determination of Tafel constants and corrosion rates. It is also shown that values for corrosion potentials can be obtained with good accuracy when exchange current densities of anodic and cathodic reactions are known. This method overcomes some of the earlier drawbacks of the two-electrode technique, such as the need for separate, three-electrode Tafel constant determinations.
