- 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.
