.... In Figure 5(d)–(f) , the effect of pitting corrosion is reduced, and the areas affected by intergranular corrosion become more prominent. For E.C.s, 4, 5 and 6, the experiments were carried out with a low pulse-on time, which reduces the pulse-off time. As discussed above, the re-passivation layer formed...
