摘要
The corrosion behaviour of 11Cr1Si ferritic/martensitic (F/M) steel in static liquid lead–bismuth eutectic (LBE) at 450–550 °C was investigated. The results show that the oxide layer on 11Cr1Si F/M steel exposed in LBE at 450–550 °C appeared different structural characteristics. The oxide layer on 11Cr1Si F/M steel at 450 °C was composed of an outer Fe3O4 layer on the top of an inner Fe-Cr spinel layer, while the oxide layer at 500 °C and 550 °C consisted of an outer Fe3O4 layer, an inner Fe-Cr spinel layer and the irregular internal oxidation zone. Meanwhile, the thickness of the oxide layer obviously increased with increasing temperature and time. The corresponding corrosion appearances and mechanisms were also discussed.
