Abstract:

采用全浸泡腐蚀方法,利用扫描电镜(SEM)、能谱分析(EDS)、X射线衍射(XRD)、失重法、极化曲线和交流阻抗(EIS)等分析手段,对超级13Cr油管钢在不同pH值NaCl溶液中的腐蚀形貌、腐蚀速率、腐蚀产物及其腐蚀膜层的电性能进行了分析,研究了超级13Cr油管钢在NaCl溶液中的腐蚀行为与腐蚀膜层电性能,结果表明超级13Cr油管钢在酸性的NaCl溶液中具有较好的抗腐蚀性能,其表面腐蚀膜层具有钝化特性,随着溶液pH值的降低,其腐蚀膜层的钝化性能增强,发生点蚀的倾向性减小,而发生全面腐蚀的倾向性增大,其腐蚀产物为Fe和Cr的氧化物组成。当溶液pH值大于4.5时,腐蚀速率随着溶液pH值的减小而增大;当溶液pH值小于4.5时,腐蚀速率随着溶液pH值的减小而减小。
