| 摘 要： | 利用光学显微镜、扫描电镜、电子能谱等测试手段，从材料成分、微观组织、断口形貌以及腐蚀产物成分等角度，分析了板式换热器不锈钢板片穿孔泄漏的原因。结果表明，不锈钢板片失效的主要原因是氯离子引起的缝隙腐蚀所致。

| Abstract: | The leakage of plates in plate steel heat exchanger was analyzed by using op tical microscope, SEM, electronic energy spectrum in material composition, micro structure, fracture surface, and composition of corrosion product. The results i ndicted that the failure of the stainless steel plates was mainly due to crevice corrosion induced by Cl-. |
