Abstract

The study of Alloy 22 was undertaken in several selected mixed nitrate/chloride (NO₃^-/Cl^-) electrolytes with chloride concentrations [Cl^-] of 1.0, 3.5 and 6.0 molal with [NO ₃^-]/[Cr] ratios of 0.05, 0.15 and 0.5 at temperatures up to 100°C. The repassivation potentials increased with an increase in [NC₃^-]/[Cr] ratio and decreased with an increase in temperature. The absolute [Cl^-] was found to have less of an effect on the repassivation potential compared with temperature and the [NO ₃̇]/[C1̇]. Regression analyses were carried out to describe the relationship between the repassivation potential, temperature, [Cl ^-] and [NO₃̇] for the conditions tested.
