| 中文摘要: |
| 生物膜是一种依附于载体表面的特殊微生物聚集体,它的存在会创造异样的表面环境从而影响管线钢的应力腐蚀。近年来,管线钢在生物膜作用下应力腐蚀开裂行为已经成为学界的一个研究重点。本文综述了生物膜的形成和应力腐蚀开裂行为的机理及其影响因素,总结了关于生物膜和应力协同作用下管线钢应力腐蚀开裂行为的研究现状,分析了当前研究中存在的不足并作了展望。 |
| 英文摘要: |
| Biofilm is a kind of special microbial aggregates that adheres on the carrier’s surface and creates an unusual surface condition facilitating the stress corrosion of pipeline steel. In recent years the stress corrosion cracking behavior of pipeline steel under the action of biofilm has been studied as an academic research focus. This paper summarizes the mechanism of biofilm formation and stress corrosion cracking, as well as their influencing factors. It also outlines the research status over the synergistic effect of biofilm and stress on the corrosion behavior of pipeline steel, and provides a critical and prospective discussion for both current research and future trends. |
