交流杂散电流对X80管线钢腐蚀行为的影响
Effects of Alternating Stray Current on Corrosion Behavior of X80 Pipeline Steel
摘 要
采用失重法研究了不同电流密度(0～200 A/m2)的交流杂散电流对X80管线钢腐蚀的影响,并且采用扫描电镜(SEM)、X射线衍射仪(XRD)和能谱仪(EDS)观察分析X80管线钢腐蚀后基底的微观形貌以及腐蚀产物的表面形貌、结构组成和物相成分.结果表明,随着交流杂散电流密度的增加,X80钢的腐蚀速率先是缓慢增大,随后快速增大,最后增大趋势减缓,并不会无限制增大.腐蚀产物分为两层,外层是红棕色的Fe2O3和棕黄色的FeOOH混杂在一起的疏松多孔的结构,内层是黑色的Fe3O4形成的致密结构.低电流密度时,腐蚀形式主要是均匀腐蚀;高电流密度时,腐蚀形式转变为局部腐蚀.

Abstract
Weight loss test of X80 pipeline steel samples was performed in soil simulated solutions at various AC current densities from 0 to 200 A/m2.The microstructure of X80 pipeline steel after corrosion,the surface appearance,structural composition and phase constitution of corrosion products were studied by SEM,EDS and XRD analysis techniques.The results showed that the corrosion rate of X80 pipeline steel increased first slowly and then rapidly,at last the increase tendency slowed down and would not be unlimited increase as AC current density increased.The corrosion product was divided into two layers.The outer layer was a kind of porous structure and consisted of red-brown Fe2O3 and yellow-brown FeOOH.The inner layer was a kind of dense structure and consisted of black Fe3O4.At a low AC current density,uniform corrosion occurred,while at a high AC current density,pitting corrosion occurred extensively on the X80 pipeline steel sample surface.
