摘要
Pre-oxidation of porous ferritic Fe22Cr alloys was extensively studied in this paper. Weight gain measurements and SEM analysis revealed that pre-oxidation performed at 900 degrees C for 40 min increased the lifespan of the alloy. A Cr evaporation study did not disclose any significant influence of the pre-oxidation process on the Cr content in the alloy. For a more detailed assessment, TEM imaging and X-ray tomography measurements of pre-oxidized samples were performed. These analyses showed that alteration in the grain and grain boundary diffusion fluxes might be the key for explaining the corrosion prevention role of pre-oxidation.
