Konysheva, U. Seeling, A. Besmehn, L. Singheiser, K. Hilpert] The chromium vaporization rate of the Crofer22APU steel as compared to Cr5Fe1Y2O3 alloy was studied under humidified air at 800°C over a period of up to 1300h by using the transpiration method. Under oxidizing atmosphere, the Crofer22APU steel forms a (Cr,Mn)3O4 spinel layer on the surface, which hinders chromium release at 800°C by about a factor of 3 as compared to Cr5Fe1Y2O3 alloy forming a pure chromia scale. The impact of minor alloying additives in the Crofer22APU ferritic steel on the chromium vaporization was considered. The steel with the lowest amount of Al and Si in the matrix exhibits a low chromium vaporization rate over 1300h. The microstructure and composition of the oxide scales and surfaces formed were investigated using high-resolution scanning electron microscopy, X-ray photoelectron spectroscopy and time-of-flight secondary ion mass spectrometry. The results obtained give insight into the chromium vaporization mechanism. Springer Science+Business Media, LLC, 2007 Konysheva E.
