| 摘 要： | 利用X射线衍射仪(XRD)、扫描电镜(SEM)和能谱仪(EDS)等,对800H合金高温氧化膜的增厚动力学、形貌及氧化物组成进行了分析。结果表明,700和800℃下形成的氧化膜相近,由(Cr,Fe)2O3和Mn-Cr氧化物组成;900℃时的氧化膜急剧增厚,里层依然是Cr2O3,中间层则是Cr-Fe-Mn氧化物,外层为富Ti的氧化物。通过热力学和动力学计算,提出了800H合金氧化膜形成的模型,发现TiN的存在改变了氧化膜的结构。

| Abstract: | Oxidation kinetics,morphology and constitution of oxides formed on alloy 800 H at high temperature were analyzed by means of X-ray diffraction,scanning electron microscopy and energy dispersive spectroscopy.The results show that the scales formed at 700 ℃ are similar to that formed at 800 ℃,mainly composed of(Cr,Fe)2O3 and Mn-Cr oxides.The scales formed at 900 ℃ are much thicker with three layers: an inner layer of Cr2O3,an interlayer of Cr-Fe-Mn oxides and an outer layer of Ti-riched oxides.The oxidation of 800H alloy is simulated by thermodynamics and kinetics calculation,and TiN particles are considered to change the scales structure. |
