摘要为了研究核电用2.25Cr-1Mo钢的抗蒸汽氧化性能,在500 ℃、0.1 MPa水蒸气条件下,对2.25Cr-1Mo耐热钢进行了600 h的氧化试验,利用分析天平测定样品氧化增重,获得氧化动力学曲线,通过扫描电镜观察分析了氧化膜的形貌和结构,结合X射线衍射和能谱分析对氧化产物进行物相分析。试验结果表明,2.25Cr-1Mo耐热钢的氧化增重曲线符合立方规律;氧化膜为双层结构,氧化膜内层较为致密的主要物相为(Fe,Cr)₃O₄尖晶石,氧化膜外层疏松多孔主要物相为Fe₃O₄和少量Fe₂O₃;腐蚀速率测定结果表明,该材料具有较好的抗蒸汽氧化性能。

Abstract：In order to study the steam oxidation resistance of 2.25Cr-1Mo steel for nuclear power. A steam oxidation experiment of 2.25Cr-1Mo heat-resistant steel was carried out at 500 ℃ in 0.1 MPa for 600 h. Oxidation kinetics formulae was acquired from the weight gains results by analytical balance. Morphology and layered structure of oxide scales were characterized utilizing SEM. Phases of oxide products were identified by XRD and EDS. Results show that the steam oxidation weight gains curve of the 2.25Cr-1Mo steel conforms to the cubic law. The oxide scale has a double-layered structure,in which the inner layer is denser and the main phase is (Fe,Cr)₃O₄spinel,while the outer layer is loose and porous and the main phase are Fe₃O₄and Fe₂O₃. The measurement results of the corrosion rate of 2.25Cr-1Mo steel show that it has good resistance to steam oxidation.
