| 摘 要： | 用质量分数3.5%的NaCl溶液作为腐蚀液,滴于低碳铁素体钢、09CuPCrNi钢和低碳贝氏体钢的表面并形成薄液膜,用金相显微镜观测薄液膜下三种钢的初期腐蚀.低碳铁素体钢和09CuPCrNi钢均出现了明显的晶界择优腐蚀,而低碳贝氏体钢没有出现明显的晶界择优腐蚀.钢基体的电化学阻抗谱和极化曲线测量结果显示低碳贝氏体钢具有最高极化电阻和最小腐蚀电流,表明细晶组织的低碳贝氏体钢的初期腐蚀速率低于其他两种钢.

| Abstract: | 3.5% NaCl(mass fraction)aqueous solution as corrosion medium was dropped onto the surfaces of low-carbon ferritic steel,09CuPCrNi steel and low-carbon bainitic steel to form thin liquid films.Initial corrosion of the steels was observed by metallographic microscope.Selected attack along grain boundaries occurred in both low-carbon ferritic steel and 09CuPCrNi steel,while this did not occur in low-carbon bainitic steel.The electrochemical impedance spectrum and polarization curve of the steel matrixes indica... |
