...-1.5Cu) after only 30 days of exposure ( Fig. 12a ). For 70Cu-30Ni, corrosion occurred just outside of the crevice mouth and was found to be quite shallow after 6 months ( Fig. 12b ). In contrast, crevice-related corrosion of alloy 400 (70Ni-30Cu) was more severe after only 45 days ( Fig. 12c ). In some...
