Abstract

The relation between the thermo-ionic work function and the corrosion rate of the metals have been theoretically studied by means of the theory of the absolute electrode potential. At a given current density, the cathodic activation over-potentials of both either the hydrogen electrode and the oxygen electrode, decrease approximately in a linear relation to the increase of the work function, but the anodic oxygen activation over-potential changes in a reverse trend to the cathodic activation over-potential when the difference of the activation energies is small. In the case of the activation-controled corrosion, the corrosion rate of common metals decrease roughly according as the work function increases.
