| Through the case study of AC corrosion on pipeline with cathodic protection, the interference trend of AC facilities such as AC transmission line on buried pipeline, the characteristics, occurrence conditions and influencing factors of AC corrosion of pipeline with cathodic protection are summarized. The main influence of alternating current on the electrode process and polarization behavior of pipeline steel material activation and passivation system, and the synergistic acceleration of high cathodic protection level on AC corrosion are summarized. This paper systematically describes the latest research progress in the mechanism and evaluation criteria of AC corrosion of pipelines under cathodic protection. The main viewpoints and influencing factors in the mechanism model of AC interference corrosion are discussed, and the problems in cathodic protection technology of pipeline under the condition of AC interference are expounded. |
