摘要：
In this paper, the oxidation process of high-chromium steel under different heating conditions in dry air is analyzed. The results show that there is a special "weight gain platform" in the oxidation kinetics curve of highchromium steel. During the isothermal oxidation process, Fe oxides will preferentially grow near the carbide grain boundaries and ultimately diffuse to the surface of the high-chromium steel. In addition, during oxidation, No oxide is formed near the carbide grain boundaries. Based on these results, a pre-oxidation scheme was proposed and shown to improve the oxidation resistance of high-chromium steel by 40% in water cycle oxidation.
