| 摘 要： | 通过对锅炉管材的机械性能，化学成分测定和对金相组织，腐蚀产物的分析及电极电位，极化曲线的测定，找出了锅炉管坑孔腐蚀原因，是由于在锅炉工作和停运时氧溶入使Fe3O4氧化成Fe2O3 在高温条件腐蚀产物下形成碱浓缩导致碱腐蚀。

| Abstract: | Presents the identification of cause for leakage from 200 MW boiler tube by testing for mechanical property and chemical composition, analysis of metallographical organism and corrosion products and testing for electrode potential and polarization curve of boiler tube material,and points out alkaline corrosion occurs during boiler operation and shutdown when oxygen dissolves into water and Fe 3O 4 Fe 2O 3 and corrosion products lead to condensation of alkali at high temperature. |

| Keywords: | point corrosion electrode potential polarization boiler power plant |
