摘要
【目的/意义】藻类附着引发的微生物诱导腐蚀(MIC)对金属、混凝土及涂层构成严重威胁。本文系统阐述了藻类对金属、混凝土和涂层的腐蚀行为与机理及涂层中藻类抑制剂的研究进展。【分析/评论/进展】藻类黏附在金属表面会造成局部腐蚀,加速点蚀发展;藻类在混凝土表面的附着会加快混凝土老化,使其抗压强度下降;藻类附着涂层表面会诱发应力开裂,加速涂层老化失效。藻类抑制剂抑制机理主要为:通过破坏藻类细胞膜物质使其死亡;通过抑制细胞内叶绿体等细胞器的活性影响细胞的光合作用或代谢活动使其死亡。【结论/展望】未来藻类抑制剂应向环境友好和长效持续抑制方面发展。
[Objective/Significance]Microbiologically influenced corrosion(MIC)caused by algal attachment poses a serious threat to metals,concrete,and coating.This paper reviews the corrosion behaviors and mechanisms of algae on these substrates,as well as the recent progress in algal inhibitors in coating.[Analysis/Discussion/Progress]Algal adhesion on metal surfaces can induce localized corrosion and accelerate pitting.On concrete,the attachment of algae accelerates concrete aging and reduces its compressive strength.For coating,algal colonization induces stress cracking and accelerates degradation.The primary mechanisms of algal inhibitors include disrupting the integrity of algal cell membranes,leading to cell death,and inhibiting key cellular processes such as photosynthesis by targeting organelles like chloroplasts.[Conclusion/Prospect]Future research on algal inhibitors should focus on enhancing environmental compatibility and achieving long-lasting inhibitory efficacy.
