The well‐known Stern–Geary equation was derived on the basis of the theory by Wagner and Traud and relies on the so‐called mixed potential of an electrode subject to uniform corrosion. Nevertheless, it is common practice to apply the linear polarization method to determine instantaneous corrosion ra...
