摘要	The corrosion behavior of an Al-containing oxide dispersion strengthened (ODS) steel at 600 and 700 degrees C degrees C oxygen- saturated static Pb-Bi eutectic was investigated with and without a pre-oxidation heat treatment. Without pre- oxidation, the ODS steel formed a multilayer oxide scale consisting of outer Pb-Fe-O/magnetite and inner FeCr-Al spinel/Cr(Al)-rich film on the surface during the corrosion exposure at 600 degrees C degrees C up to 3100 h. In contrast, the pre-oxidized ODS samples was covered by a thin, dense and continuous pre-formed Al2O3 2 O 3 scale, which effectively improved the corrosion resistance. Although the Al2O3 2 O 3 scale was gradually reacted with Pb-O clusters to form Pb-Al-O compound with the prolonged exposure time to 3100 h, the total thickness of oxide layers was still less than about 1 mu m. Exposed to elevated temperature of 700 degrees C, the corrosion mode changed significantly. Both ODS samples spontaneously formed an external Al2O3 2 O 3 during the exposure for 100 h. However, with prolonged exposure time to 500 h at 700 degrees C, the integrity of the protective Al2O3 2 O 3 scale gradually destructed. Small nodule-like oxides emerged from localized areas in the pre-oxidized samples, while more thicker oxide layer was form in the as-received samples. which intensified corrosion by the aggressive LBE melt. The results suggest that optimized pre-oxidation treatment can effectively to improve the corrosion resistance of Al- containing ODS steel.
