| 摘 要： | 对无缝钢管顶头20CrNi3A钢在水蒸气气氛下进行氧化,采用X射线衍射分析、金相分析和硬度测试等方法,对20CrNi3A钢表面氧化膜的氧化动力学规律、组织形貌和力学性能变化进行研究.结果表明:20CrNi3A钢的氧化动力学曲线与金属氧化动力学曲线规律相符;在同一氧化时间下,随着氧化温度的增高,氧化膜的厚度逐渐变大;当氧化温度为900℃、氧化时间为8 h时,氧化膜厚度最大,硬度最佳.

| Abstract: | The seamless steel tube head 20CrNi3A steel is oxidized in the water vapor atmosphere.The oxidation kinetics,microstructure and mechanical properties of the surface oxide film of 20CrNi3A steel are studied by XRD,metallographic analysis and hardness test.The results show that the oxidation kinetics curve of 20CrNi3A steel is consistent with the metal oxidation kinetic curve.The thickness of the overall oxide film gradually increases with the increase of the oxidation temperature and the extension of time.Thickness of the oxide film reaches its largest scale and the hardness reaches its best level with oxidation temperature of 900℃for 8 h. |
