| 摘 要： | 对比研究了新型含铝高铬铸铁的高温耐腐蚀性能。利用失重法测绘了合金的腐蚀动力学曲线;用扫描电子显微镜对热腐蚀后氧化膜(腐蚀膜)的形貌进行观察,并分析其化学成分分布;借助旋转阳极衍射仪对热腐蚀产物进行物相分析;并讨论了新型含铝高铬铸铁的热腐蚀机理。结果表明,与普通高铬铸铁相比,在长时间高温热腐蚀过程中,新型含铝高铬铸铁表面的氧化膜具有更好的完整性和致密性,使得基体在热腐蚀过程中一直保持很低的腐蚀速率,使腐蚀介质无法扩散到基体,不易造成进一步腐蚀破坏。 |
| 关 键 词： | 高铬铸铁 含铝高铬铸铁 腐蚀速率 耐热腐蚀 |

| Abstract: | High-temperature corrosion resistance of a new aluminum-containing high chromium cast iron was investigated compared with the comventional cast iron.The corrosion kinetics curve of the alloys was measured using weight loss method.Scanning electron microscope(SEM) was used to observe the surface morphology of oxide film(corrosion film) on the hot corrosion,and analyze the chemical composition distribution as well.Phase analysis was carried out on the hot corrosion products by means of rotation anode diffract... |
| Keywords: | high chromium cast iron aluminum-containing high chromium cast iron corrosion rate hot corrosion resistance |
