| 英文摘要 | The phase composition of the pre-oxidized film on an alloy surface usually has a great influence on its corrosion resistance. In this work, the surface oxide film growth behavior in low-oxygen atmosphere at 720 degrees C of two 12Cr heat-resistant steels with different Mn content was studied, and their corrosion resistance in liquid lead-bismuth eutectic (LBE) with saturated oxygen at 600 degrees C was tested. The results indicated that the pre-oxidized film of 1.6Mn steel is mainly composed of large-size Mn-Cr spinel and Fe-Cr spinel, while that of improved 0Mn steel is mainly composed of continuous and dense Cr2O3 and Fe-Cr spinel. This is because Mn has a high diffusion rate in Cr2O3, so it can pass through the Cr2O3 layer and combine with O to form Mn-rich oxides, and then the Mn-rich oxides react with Cr2O3 to form Mn-Cr spinel. However, due to the high solubility of Mn in LBE, the Mn-rich pre-oxidized film of 1.6Mn steel will dissolve and fail quickly, so its long-term corrosion resistance in LBE is lower than that of 0Mn steel. |
