Żurek, A. Jaroń, M. Homa] This work presents the results of a morphology analysis of the scale formed on Crofer 22APU steel at high temperature in atmospheres containing SO2. The studies of steel oxidation were conducted on pre-oxidised and non-pre-oxidised steel within the temperature range of 700-900°C in a mixture of air of a varying SO2 content and in pure air. In the case of oxidation in pure air it was established that on the surface of the Crofer 22APU a two-layer scale is formed. The outer layer of the scale contains MnCr2O4, whereas the inner layer contains Cr2O3. The scale formed in the atmosphere containing SO2 is also comprised of two layers (outer MnCr2O4 and inner Cr2O3). The analyses were carried out with the use of the 35S isotope. The analyses of the phase composition and morphology of the formed scale were conducted with the use of SEM/EDX and TEM.
