利用扫描电镜，能谱仪及X-射线衍射对高温高压水蒸气条件下的12Cr1MoV钢氧化膜成分及结构进行观察和分析。结果表明：12Cr1NoV耐热钢在高温高压水蒸汽条件下长时间的氧化后，形成多层氧化膜。氧以及合金元素Cr，No等在各层氧化膜中的含量差异较大，最外层和中间层主要是富铁的Me3O4型氧化物，最内层是具有一定保护性的FeCr2O4型尖晶石结构氧化物。

The microstructure of the oxidation layers of 12Cr1MoV steel tube under the high-temperature and high-pressure water vapor was observed by using SEM and the phase structure of the oxide layer was analyzed by energy spectrum and XRD. The results showed that multi-layer oxide films formed in these steel pipes under high temperature and high pressure water vapor condition. The content of O and alloy elements such as Cr and No are greatly different in different layers. The main contents in outer and middle layers were high-Fe Oxide-Me3O4 and in inner la...
