摘要:

利用电子显微镜和能谱等现代分析仪器,系统研究了YUS701型高Cr-Ni奥氏体不锈钢在1 200 ℃超高温腐蚀介质环境下长期服役过程中的氧化腐蚀特征及失效机理.研究结果表明:不锈钢表面氧化膜具有多膜层结构,氧化环境及基体-氧化层界面处的元素分布和扩散对氧化膜的结构与性能有重要影响;氧化膜的失效行为主要表现为氧化层中裂纹的产生和不致密氧化层的剥落.

Abstract:

The oxidative corrosion characteristics and failure mechanism of YUS701 high Cr-Ni austenitic stainless steel in long-term service under the environment of ultra-high temperature corrosion medium at 1 200 °C were systematically studied by using modern analytical instruments such as electron microscope and energy spectroscopy. The results show that the oxide film on the surface of stainless steel has a multi-layer structure, and the oxidation environment and the distribution and diffusion of elements at the matrix-oxide interface have important effects on the structure and properties of the oxide film. The failure behavior of the oxide film is mainly manifested as the generation of cracks in the oxide layer and the peeling of the non-dense oxide layer.
