摘要
介绍了在水蒸气气氛中,含铬、硅合金钢的高温氧化动力学遵循S曲线,即第一阶段的慢速氧化、第二阶段的快速氧化和第三阶段的慢速氧化。分析了在氧化初期,具有保护性的Cr_2O_3/SiO_2氧化层在钢表面的生成阻碍了离子的扩散,随后保护层的失效导致快速氧化。讨论了在含有水蒸气的高温氧化条件下,氧化皮截面通常呈三层结构。指出了通常水蒸气促使形成了含更多孔的氧化皮,多孔结构增大了氧化皮的剥离倾向。
The oxidation kinetics of chromium and silicon steel in water vapor following the S curve were introduced,the first slow oxidation stage,the second rapid oxidation stage and the third oxidation stage.The formation of protective Cr_2O_3/SiO_2layer on the steel surface preventing the diffusion of ions were discussed,and following the failure of the protective layer leaded to the rapid oxidation.The cross-section of the oxide scale normally with three-layer structure under the high temperature oxidation in water vapor were analyzed.Generally,the water vapor promoting the formation of more porous scales was pointed out and then the porous structure increased the tendency of the peel of the oxide scale.
