摘要: 采用动电位极化、电化学阻抗谱（EIS）测试、浸泡实验、SEM和EDS分析研究了Cr的添加对铸态X52钢在湿H₂S环境中腐蚀行为的影响。结果表明，Cr的添加，对阴极反应有显著的抑制作用，提高了铸态X52钢的耐蚀性。但耐蚀性并不总是随着Cr含量的升高而增强。Cr的添加对腐蚀产物的形貌有很大影响，使表面腐蚀产物由疏松多孔变为致密平整。内层富Cr腐蚀产物的出现，使腐蚀速率明显降低。

Abstract：To elucidate the effect of Cr on the corrosion behavior of cast X52 steel in H₂S containing environments, potentiodynamic polarization tests, electrochemical impedance spectroscopy (EIS) measurements, immersion tests SEM and EDS analysis were conducted. The results show that Cr addition leads to a remarkable decrease in the cathodic current density. However, the corrosion resistant did not increase linearly with the increasing Cr content. The addition of Cr altered the corrosion morphology, whilst the formed oxide scale transformed gradually from porous to compact. SEM-EDS analysis revealed the presence of Cr-rich corrosion products in the inner portion of the formed oxide scale, which may be responsible to the distinct drop in corrosion rate.

Key words： cast X52 steel electrochemical corrosion Cr-rich oxide
