摘　　要：微生物腐蚀研究一直都是金属腐蚀领域关注的热点,微生物种类的不同,对金属材料的腐蚀影响也不尽相同。实际环境中,微生物的复杂性导致单一微生物的腐蚀机理并不能完全解释实际的腐蚀现象,因此混合微生物体系研究成为微生物腐蚀领域新的研究方向。在基于单种微生物对金属的腐蚀行为及其腐蚀机理的研究基础上,综述了两种微生物的混合体系在金属表面对其腐蚀的影响。归纳总结了混合微生物的构成,重点综述了含有SRB、IOB和其他典型微生物的混合体系的作用过程,分析了混合体系中,不同微生物的相互作用(如协同、竞争作用等)对金属腐蚀影响。梳理了目前混合微生物体系研究的实验环境,并针对混合微生物体系在金属表面腐蚀微观的研究,介绍了几种技术,以期能更加直观地显示混合体系中微生物间的作用机制。最后对研究两种微生物混合体系下的金属腐蚀问题提出了建议和发展方向。Microbiologically influenced corrosion(MIC)is always a hot topic in the field of metal corrosion.Different microbial species also have different effects on the corrosion of metal materials.The corrosion mechanism of single microorganism in actual environment could not fully explain the actual corrosion phenomenon due to the complexity of microorganism.In recent years,the study of mixture microorganism system has become a new research direction in the field of microbiologically influenced corrosion.The corrosion of mixture microorganism system of two microorganisms on metal surface was discussed according to the research on corrosion behavior and corrosion mechanism of single microorganism.The composition of the mixed microorganism was summarized,and the action process of the mixed system containing SRB,IOB and other typical microorganism was analyzed,and the effects of the interactions of different microorganisms in the mixed system on metal corrosion,such as synergism and competition,were studied.The experimental environment of current mixed microorganism system was reviewed.Several technologies were introduced to study the corrosion microstructure of mixed microorganisms on metal surface in order to show the interaction mechanism of microorganism in the mixture system more directly.Some suggestions and development directions for the study of corrosion problems in mixed microorganism system were proposed.
