| 中文摘要: |
| 微生物腐蚀(Microbiological Induced Corrosion，MIC)带来的危害占海洋腐蚀危害的20%。微生物腐蚀是指由于微生物的生命活动及其代谢产物与金属材料相互作用，影响腐蚀反应的阴极和阳极过程所引发的腐蚀现象，已成为海运业面临的重大技术难题，研究海洋微生物腐蚀对推进我国海洋事业的发展有重要意义。金属材料微生物腐蚀包括全面腐蚀和局部腐蚀，局部腐蚀的危害更大，而点蚀被认为是危害最大的局部腐蚀形式。海洋微生物种类繁多，本文聚焦于硫元素的参与者硫酸盐还原菌(Sulfate-reducing Bacteria，SRB)、铁元素的参与者铁还原细菌(Iron-reducing Bacteria，IRB)和铁氧化细菌(Iron-oxidizing Bacteria，IOB)所引发的微生物点蚀问题，包括由细菌不均匀的生物膜与腐蚀产物膜以及细菌本身的特性引起的点蚀。以广泛应用于海洋平台和船舶的碳钢和不锈钢为对象，分析其在海洋SRB、IRB和IOB下的点蚀状况，从腐蚀形貌和腐蚀产物两方面对比了碳钢、不锈钢在不同细菌体系中的腐蚀差异，腐蚀形貌分析包括腐蚀产物形貌和去除腐蚀产物后金属表面形貌的分析，腐蚀产物分析主要聚焦于金属材料表面不同成分与含量的变化。从代谢产物理论、氧浓差电池作用理论阐释了碳钢和不锈钢的点蚀机理，指出微生物点蚀研究需要综合考虑多种因素，包括多菌种的相互作用和多种环境因素对金属材料的点蚀影响，以及微生物对耐蚀金属材料的点蚀影响等。 |
| 英文摘要: |
| Microbiological Induced Corrosion (MIC) occurs due to the interaction of the activities and metabolites of the microorganisms with metal materials, which affects the cathodic and anodic processes of corrosion reactions. This phenomenon accounts for approximately 20% of marine corrosion hazards, rendering it a major technical problem for the marine industry. The study of microbial corrosion in marine environments is of great significance to promote the development of the Chinese marine industry. Microbial corrosion of metal materials includes both comprehensive corrosion and local corrosion, with local corrosion being more harmful. Among various forms of local corrosion, pitting corrosion is considered the most harmful. |
