Alternating Current Induced Corrosion of Buried Metal Pipeline: A Review

Alternating current(AC) induced corrosion is defined that the electrochemical corrosion process of metals caused by alternating current. Buried metal pipelines are frequently damaged when the alternating current applied. With the increasing cases that high-voltage transmission lines and/or electrical traction system cross over or parallel to buried pipelines, the AC corrosion becomes increasingly serious and the hazard of AC corrosion on buried pipelines can not be ignored. Although the research on AC corrosion has a history over centuries, there are still many difficult problems to be solved. Issue regarding AC corrosion has been intensively and extensively focused on. In this paper, the research progress on the characteristics, mechanism, influencing factors of AC corrosion and the effect of AC corrosion on cathodic protection and microbial corrosion in recent years were reviewed systematically. By discussing the key problems existing in the current research, this paper looks forward to the research prospect and development trend of this field, and provides new ideas for researchers in related fields.
