    Research Progress in Microbial Corrosion of Metallic Materials

    • 摘要: 金属材料因力学性能良好而被广泛应用,但因其结构受到外界环境的影响易发生腐蚀失效。其中作为腐蚀类型之一的微生物腐蚀,所造成的经济损失和安全问题是无法忽视的。系统总结不同服役环境下金属材料微生物腐蚀研究现状,针对广泛存在的硫酸盐还原菌和氧化亚铁硫杆菌的腐蚀机理研究进行综述,并简要归纳了微生物腐蚀控制方法。最后,展望金属材料微生物腐蚀研究的未来发展趋势,为防护材料和控制微生物腐蚀提供新思路。

       

      Abstract: The metal materials were widely used for their good mechanical properties, but due to the susceptibility of their structural to external influences, they were prone to corrosion failure. One of the types of corrosion is microbial corrosion,caused by the economic losses and the safety issues can not be ignored. The current state of research on the microbial corrosion of metal materials under different service environments was systematically summarized, with a particular focus on the typical corrosion mechanisms of the widespread sulfate-reducing bacteria(SRB) and Thiobacillus ferrooxidans(T. ferrooxidans). The control of microbial induced corrosion methods was briedly summarized. Finally, the future development trend of microbial corrosion research on metallic materials was looked forward. New ideas for protective materials and microbial corrosion control were provided.
