Alloys of Ni with 10–99wt.% Fe were examined in 25wt.% KOH at 80°C. Electroactivity of the alloys toward HER increased with the increasing content of Fe up to about 90wt.%, however also increased tendency to pitting corrosion during cathodic polarization. After anodic polarization or corrosion at OCP, cathodic curves of high-Fe materials exhibited a peak which was followed by significant current rise...
304L and 316L steels were nitrided at 425°C for 30h and examined at various depths in 0.1M Na 2 SO 4 acidified to pH 3.0. In the near-surface region with about 7–14wt% N, at potentials of active state anodic currents were much higher than those for untreated steels, whereas in deeper regions with <7wt% N the currents were only slightly increased in comparison with untreated steels...
