Abstract：Pipeline steel holds an irreplaceable position in the modern long distance industry, it is most commonly used in the transportation involving petroleum, gas, coal, and building materials slurry. Most of modern pipeline steel is taken coating as the outer anti-corrosion measures, inevitable resulting in disbonded areas due to external force during the process of buried installation and use. With the electrolyte infiltration and long-term chemical and electrochemical evolution, it forms a special corrosion system in the disbonded area, which could shorten the service life of the pipeline steel quickly, and causing a great potential hazard to industrial production and people's daily life. Therefore, the corrosion of pipeline steel with the disbonded coating has the highest priority and becomes a cutting-edge research topic of the scholars in the corrosion filed at home and aboard. A summary on disbonded system with domestic and foreign research is made from the aspects of research model, classical theory, impact factors, and research progress in recent years. Based on the insufficient result of existing research, the prospect for the future work is investigated.
