Influence of Anaerobic Micro-organisms on Corrosion Behavior of Copper
摘 要
采用开路电位、电化学极化曲线、电化学阻抗谱(EIS)研究了紫铜在海洋厌氧菌影响下的腐蚀行为。结果表明, 扫描电子显微镜SEM形貌分析结果表明在紫铜上附着的SRB海洋微生物呈微弯杆状, 材料表面形成较致密的半透明的生物细菌膜。电化学测试结果表明, 紫铜在SRB细菌培养基海水中的腐蚀过程主要受活化极化控制, SRB微生物的存在导致紫铜的开路电位和活化极化率变小, 从而加速了紫铜的腐蚀进程。
Abstract
The effects of marine anaerobic bacteria on the corrosion behavior of copper were investigated by mesuring the open-circuit potentials, polarization curves and electrochemical impedance spectroscopy (EIS). The results show that by morphology analysis using scanning electron microscopy (SEM), the marine microbes SRB adhering to copper were pole shape with microbending. There were biofilms with dense and translucent formation of bacteria on the surface of material. Electrochemical measurement results revealed that the control step for corrosion of copper in the culture medium for SRB in seawater was activation polarization process. The presence of micro-organism SRB decreased the open circuit potential and activation polarizability of copper. It can accelerate the corrosion progress of pure copper.
