2642 Research on corrosion resistance of ODS-Al steel in high temperature lead-bismuth eutectic under control of density of oxygen

Abstract

The corrosion tests have been performed to some types of the ODS (oxide dispersion strengthened ferritic) steels with different chemical compositions of chromium and aluminum in the static pool of the lead-bismuth eutectic for up to 4000 hours. The lead-bismuth eutectic was kept the high temperature of 650℃, and the oxygen concentration was controlled. As the results, chromium effect on corrosion has not been observed, and good corrosion resistance by aluminum oxide formation on the surface has been obtained.
