摘　　要：研究了预生氧化膜处理对不同工艺生产的锆 4合金试样抗疖状腐蚀的影响。预生膜能起到延缓疖状腐蚀的作用 ,但不能阻止疗状腐蚀产生。对改进工艺的试样抗疖状腐蚀的原因进行了讨论。The effect of pre oxidizing treatment on nodular corrosion of Zr 4 tube was investigated by means of microscope and autoclave techniques. The pre oxidizing treatment could retard the nodular corrosion, but could not prevent the Zr 4 tube from the nodular corrosion. The reason that the optimized technology could improve the nodular corrosion resistance was discussed.

关 键 词：预生氧化膜处理 疖状腐蚀 锆合金
