| Abstract: |
| This work investigated the corrosion and protection of metals in the process of microbial activities. Through constructing microbial environment in the laboratory, the natural corrosion behavior of metals was simulated. The research history of microbial corrosion was reviewed, and the characteristics of biofilms during the corrosion process of metals were illustrated in detail, based on the research progress in recent years. Moreover, the microbiologically influenced corrosion of metal materials for coastal industrial circulating cooling water system was introduced, relevant anti-corrosion technology was presented, and the future development trend in this field was prospected. In natural seawater, microorganisms tend to adhere to the material surface and form biofilms, which play a dual role in the metal/solution interface. The microbial corrosion of metals is usually a result of synergistic effect of various microorganisms, and has complex mechanisms. Thus, many physical and chemical methods, especially the protective coatings should be comprehensively used so as to achieve the purpose of controlling the corrosion of metals. |
