摘要

应用电化学方法和表面分析技术(AFM和SEM)研究硫酸盐还原菌(SRBB)(生物环境)及其腐蚀产物(非生物环境)对A3钢腐蚀行为的影响以及A3钢在两种不同环境下的腐蚀特征.结果表明:于不同时期生成的微生物膜和腐蚀产物膜,对材料的腐蚀起着不同的作用.生成的生物膜越厚越容易剥落,而不均匀的微生物膜将引起材料的局部腐蚀.在非生物环境中生成的腐蚀产物膜比在生物环境中生成的膜更加紧密地黏附于金属的表面.

Abstract

Electrochemical techniques and surface analysis techniques were applied to study corrosion characteristic of A3 steel.The effects on corrosion behavior of A3 steel by sulfate-reducing bacteria(SRB)(biotic media)and corrosion product(abiotic media)were studied.The results showed that biofilms and corrosion product films play different role during different stages.Biofilms were easier flaky with increasing of its thickness.Non-uniform biofilms reduced pitting corrosion of the specimens.The corrosion product films formed under abiotic conditions were more adherently to the surface of the metal than those formed in biogenic media.
