| 摘 要： | 采用表面分析法、X射线衍射和微生物技术，综合研究了核电厂球墨铸铁材料饮用水管线的腐蚀失效行为。结果表明，微生物腐蚀引起的腐蚀瘤是导致管线失效的直接原因，局部氧浓差腐蚀起到了一定的加速作用。

| Abstract: | The corrosion failure behavior of ductile iron potable water pipeline in a nuclear power plant was investigated by surface analysis method,X-ray diffraction and microbial technology.The results showed that tubercles caused by microbiologically influenced corrosion led to the pipeline failure directly.The local oxygen-concentration corrosion was another cause for accelerating the corrosion rate. |
