| 摘 要： | 借助于金相显微镜、扫描电子显微镜对J55油管腐蚀失效原因进行了分析。认为，油管失效是由于微电池腐蚀造成的，腐蚀先在钢管外表面能构成电池回路的珠光体晶粒中进行，然后逐渐扩展到周围的晶粒。

| Abstract: | With the aid of optical microscope and SEM with Energy Dispersive Analyzer (EDX), we analyzed the corrosion failure of J55 oil pipe, and found out that corrosion was the result of the micro cell corrosion. Micro cell corrosion originally carried out in pearlites on the external surface of the pipe where micro cell circuit could be formed, and gradually developed and spreaded. |
