In 1938 Wagner and Traud1 published a paper: Concerning the Evaluation of Corrosion Reactions by Superposition of Electrochemical Partial Reactions and Concerning the Potential Formation on Mixed Electrodes. This paper is today considered the classical paper on mixed potential theory, which postulates that, even without the assumption of the existence of local anodes and cathodes, one can explain corrosion reactions by assuming that cathodic and anodic partial reactions occur at the phase boundary metal/electrolyte in constant change with statistical distribution of location and time of the individual reaction.
