Surface characterization of the corroded samples were performed using scanning electron microscopy (SEM) and x-ray diffraction (XRD). Webbcurrent, potentiodynamic polarization curves were obtained. In order to understand mechanism of processes that occur in nickel electrodes when they are polarized by industrial frequency alternating current, anode-cathode cyclic potentiodynamic polarization curves were measured (Figure 1).
