摘要:

在模拟潮差实验槽内，通过腐蚀形貌观察、腐蚀产物分析，以及原位开路电位监测，研究了X60管线钢在不同监测位置随潮水涨落变化的腐蚀行为与规律。结果表明，管线钢在潮差区内不同位置的腐蚀行为各异，在中、低潮区的腐蚀速度要快于最高潮区及最低潮区的腐蚀速度；随着潮位的降低，开路电位不断降低；最高潮区阴极过程主要受氧还原控制，中、低潮区涨潮时阴极过程受锈还原控制，落潮时受氧还原控制。最低潮区的电位变化过程与潮水涨落无关。

Abstract：

In an experiment tank of simulated tidal zone, the variation of corrosion behavior of X60 pipeline steel with the tidal water fluctuations at different monitoring positions was characterized by means of corrosion morphology observation, corrosion product analysis, and in-situ open-circuit potential monitoring. The results show that the corrosion behavior of pipeline steel is different at different positions in tidal zone. The corrosion rate in the middle and low tide areas is faster than that in the highest and lowest tide areas. With the decrease of tidal level, the open circuit potential decreases continuously. The cathodic process in the highest tide zone is mainly controlled by oxygen reduction. The cathodic process in the middle and low tide zone is controlled by rust reduction during high tide, and it is controlled by oxygen reduction during ebb tide. The change process of open-circuit potential in the lowest tide zone has nothing to do with tide fluctuation.

Key words： X60 pipeline steel laboratory simulation tidal corrosion open-circuit potential dry wet alternation
