摘要
本文针对日益凸显的埋地钢质管道交流腐蚀问题,比较系统地介绍了交流腐蚀的成因、形貌和机理。从钝化膜还原理论出发,根据国内外研究进展和新的标准规范,探讨了交流干扰腐蚀的评估控制技术及排流措施。
The challenges of alternating current corrosion on buried steel pipelines increased day by day.This paper systematically explain the causes,morphology and mechanism of AC corrosion.The oxido-reduction theory of the passive film have been introduced,the evaluation and control methods and mitigation measures of AC corrosion also discussed according to the new version of the international standard.
