The Nature of Anodic Films on Nickel and Single Phase Nickel‐Molybdenum Alloys

The decay of potential after anodization at a passive potential has been followed for a series of Ni--Mo alloys and the observations used to speculate on the effects of Mo alloying additives on the nature of the passivating films formed on Ni in 0.15N Na2SO4 at a pH of 2.8. It is concluded that smal...

Summary:The decay of potential after anodization at a passive potential has been followed for a series of Ni--Mo alloys and the observations used to speculate on the effects of Mo alloying additives on the nature of the passivating films formed on Ni in 0.15N Na2SO4 at a pH of 2.8. It is concluded that small quantities (# < 5 wt.-%) of Mo causes considerable defectiveness to passive films, decreasing their stability. It is proposed that at higher alloy levels, but levels which do not produce a two-phase alloy, a mixed oxide (Mo4+, Mo6+)xOy is produced along with a much less stable defective NiO.12 refs.--AA
