The amount of substance transferred per unit time at a specified surface. Using Faraday's law, the corrosion rate, , can be formally expressed as an electric current which at the corrosion potential is called the corrosion current, , e.g. for the anodic dissolution of one component of a material with in and in one obtains , being the charge number of the electrode reaction and the Faraday constant.
