The calculations were valid under the assumption that the corrosion reactions were under charge transfer control and that the mechanisms of the reactions were known. In real life, often, corrosion is a result of several reactions and it is not possible to a priori determine the reaction mechanism. In such cases Polarization Resistance, Rp, can be used to determine the resistance of the metal under investigation against corrosion. 详细>
