摘要

近年来,微生物腐蚀受到广泛重视.本文根据生物膜的结构特征,以含羧酸官能团的β_D甘露糖醛酸单元等构成的天然高分子多糖凝胶沉积于电极表面,形成模拟生物膜,初步建立起模拟生物膜环境的实验方法,并探讨了模拟海水NaCl溶液中生物膜对10CrMoAl、E2低合金钢和18_8不锈钢腐蚀行为的影响.采用极化曲线法、电偶电流测试及交流阴抗谱等电化学方法研究了上述材料在模拟生物膜环境中的腐蚀电化学行为,得到了一些有益的结果.

Abstract

Biofilm is one of the main factors that influence metal corrosion in seawater environment. According to the structure and property of biofilm, a natural biopolymeric gel,calcium alginate(an extracellular biopolymer containing carboxylate functional groups) can deposite on metal surfaces to form films. Corrosion behavior of alloyed steel E 2, 10CrMoAl and 18_8 stainless steel were studied in simulated biofilm environment by various electrochemical methods,including measurements of the corrosion potential,polarization curves,galvanic current and electrochemical impedance.The results show that such an approach is informative to reveal “how” and “to what extent” biofilm can influence the metal corrosion process.
