Corrosion of nanocrystalline and coarse-grained nickel-iron (Ni-Fe) alloys in neutral and alkaline sulfate environments

•Similar overall polarization behaviour for conventional poly- and electrodeposited nanocrystalline Ni-Fe alloys.•Differences in anodic polarization behaviour in neutral environment attributed to sulfur impurities more so than grain size.•Negligible difference in corrosion behaviour in alkaline envi...
