The cathodic polarization curve of a nickel electrode is measured in a de-aerated acid solution. The saturated calomel electrode is used as the reference. The working electrode has a surface of 2 cm². The following results are obtained: E (V) (SCE) 1 (mA) -0.55 0 -0.64 0.794 -0.69 3.05 -0.71 4.90 -0.73 8.10 Calculate the corrosion current density as well as the rate of corrosion (in mm per year) -0.77 20.0
