| 摘 要： | 材质为316L不锈钢的氧分离器在碱性环境中出现腐蚀裂纹。通过着色试验、金相检查、扫描电子显微镜、化学分析仪等检测方法,对316L不锈钢氧分离器内壁裂纹的宏观形貌、显微组织、腐蚀产物进行分析,结果表明,氧分离器封头焊接热影响区开裂是典型的应力腐蚀破坏,碱液中的溶解氧加重了腐蚀的危害程度。本文对腐蚀原因进行了分析,并针对氧分离器特殊的工作环境,提出了应对措施。

| Abstract: | Cracks are detected in the inner walls of 316L stainless steel O2 separator. Macroscopically appearance, micrographic structure and corrosion products are carried out with paint test, inspection of the metallurgical structure, scanning electron microscope (SEM) and chemical analysis. The results show that the cracks are caused by typical stress corrosion and dissolved oxygen in the alkali solution aggravates the harmfulness of the corrosion. This paper analyzes the corrosion cause and puts forward responden... |
