Solution Chemistry in Crevices on Fe-Cr Binary Alloys
Abstract
The major cation concentrations and pH's were measured in crevices on Fe-Cr alloys under potentiostatic conditions in the laboratory and on larger commercial steel specimens freely corroding in natural seawater. Crevice solutions were analyzed by thin-layer chromatography. The ratio of the cations in the crevice solutions was not equal to the ratio of the metals in the alloys; the ionic concentrations in the crevice solutions were determined, to a very large extent, by transport phenomena between the crevice and bulk solutions.
