Fundamental Studies of Dissolution and Passivity of Alloys and Compounds.
Abstract
The growth kinetics of iron at open circuit potentials in phosphate, chromate, tungstate, molybdate, and nitrite solutions were investigated using the ellipsometric technique. These results were correlated with film compositions as determined using Auger electron spectroscopy. All films thickened logarithmically with time except those formed in a pH 9.1 phosphate solution. In general the less the incorporation of ions from oxyanions in the film, the more protective the film was found to be. The exception was that formed in the chromate solution. This film was very protective and had a composition which approximated that found on stainless steels. (Author)
