摘　　要：海水是一种复杂的电解质溶液,其中富含各类腐蚀性微生物。海洋环境中广泛存在的硫酸盐还原菌(SRB)常附着在船体构件表面引发金属微生物腐蚀,进而加速钢材的腐蚀失效。为更好地了解船体钢材在海洋环境中的微生物腐蚀行为及防护措施,对船体钢材在各种服役环境下的微生物腐蚀特点进行归纳总结,并分析硫酸盐还原菌对金属的微生物腐蚀机理;阐述了海洋腐蚀研究常用的评价技术和分析方法;从钢材本身和服役环境两方面入手,进一步概括了各种SRB腐蚀防护手段的优点和不足;最后提出对未来海洋SRB腐蚀研究的展望,旨在为船体钢材的海洋SRB腐蚀防控提供理论参考。Seawater is a complex electrolyte solution,which is rich in various corrosive microorganisms.Sulfate reducing bacteria(SRB)widely existing in marine environment often attach to the surface of hull components and cause microbiologically influenced corrosion(MIC)of metals,thus accelerating corrosion failure of steel.For better studying the MIC behavior and protective measures of hull steel in marine environ-ment,this paper firstly summarized the corrosion characteristics of hull steel in various service environments and analyzed the mechanism of MIC of metal by SRB.Subsequently,the evaluation techniques and analysis methods commonly used in the study of marine MIC were described.The advantages and disadvantages of various SRB corrosion protection methods were further summarized from the aspects of steel itself and service environment.Finally,the prospect of marine MIC research in the future was proposed,aiming at providing theoretical refer-ence for marine corrosion prevention and control of hull steel.
