Abstract
It has been shown recently in a number of investigations that the presence of dispersed stable oxides in chromium-containing alloys can result in the formation of protective Cr 2 O 3 scales, which appear to grow considerably slower than similar scales on alloys not containing dispersoids. In addition, Cr 2 O 3 is removed by further oxidation to the volatile species CrO 3,and the rate of this process is unaffected by the dispersoid. Simple kinetic models have been used to describe the results, but it is suggested, on the basis of a curve-fitting analysis, that these approaches are incorrect.
