摘要
对浸泡在含ＣＯ_２的盐水中的两种Ｘ７０输送管、两种Ｊ５５套管的母材及焊缝试样的腐蚀行为进行了测试分析。结果表明，ＣＯ_２使钢的腐蚀速度、点蚀倾向和缝隙腐蚀倾向增加，而增加的幅度则受到钢的成分、显微组织等冶金因素的影响。
The corrosion behaviors of the parent meml and the weld of two types of X7O and J55 specimens in CO2 -containing salt solution have been studied.The result shows that CO2 makes the rate of corrosion,the tendency of pit and crevice corrosion increase, while the increased margin is influenced by the metallurgical parameters,including chemical composition, microstructure and so on.
