摘　　要：采用宏、微观分析、化学成分分析等手段 ,对冷却水管的腐蚀穿孔进行了失效分析。结果表明 ,水冷却器管束腐蚀穿孔主要是由于材料不合格造成的 ,冷却水在管内严重结垢给材料产生垢下腐蚀提供了条件。Research on the failure reasons of the cooling tube were carried out by means of macroexamination, thickness measurement, X ray diffraction, optical microscopy and chemical analysis. Results indicated that disqualification of material and the formation of furring in the cooling water caused the pitting and led to final accident.
