摘要:

采用带有电磁驱动轴的高温高压釜,通过失重法评价了L80、L80Cr13、22Cr、25Cr钢在含CO₂、H₂S、Cl^-的地层水中的腐蚀速率,采用SEM、EDS及XRD对其表面腐蚀产物膜进行了分析,利用AFM分析腐蚀后材料表面的粗糙度,使用CLSM分析腐蚀后材料表面的点蚀情况。结果表明,在CO₂分压为0.12 MPa、H₂S分压为0.003 MPa,Cl^-浓度为150.8 g/L,温度为80 ℃的地层水中,试样转速为100 r/min的条件下,4种钢材均匀腐蚀速率由大到小排序为L80Cr13>L80>22Cr>25Cr。L80Cr13钢表面的腐蚀产物膜主要是由Cr₂O₃与Cr(OH)₃组成,该腐蚀产物膜在Cl^-的作用下局部地方破损；L80Cr13钢发生了明显的点蚀,最大点蚀深度为11.037 μm。L80钢表面的腐蚀产物膜主要是由FeS以及疏松的FeCO₃组成,该产物膜对L80钢具有一定的保护作用,但L80钢仍旧有轻微的点蚀,最大点蚀深度为1.855 μm。22Cr、25Cr钢表面仅有一层钝化膜,且该钝化膜对基体具有良好的保护作用,基体几乎没有发生点蚀。

关键词 ：铬含量, 不锈钢, CO₂-H₂S-Cl^-, 腐蚀产物膜

Abstract：

The corrosion rate of L80, L80Cr13, 22Cr and 25Cr in CO₂-H₂S-Cl^--containing artificial stratum waters in a high temperature and high pressure autoclave equipped with electromagnetic drive shaft was evaluated by means of mass loss method. The surface morphology and element distributions of corrosion product films were analyzed by SEM, EDS and XRD. The roughness and the pitting morphology of the material surface after corrosion was characterized by means of AFM and CLSM respectively. The results suggested that the corrosion rates of L80Cr13, L80, 22Cr and 25Cr decreased sequentially in the artificial stratum water with 0.12 MPa CO₂ 0.003 MPa H₂S, 150.8 g/L Cl^- at 80 ℃ for samples with rotating speed of 100 r/min. The corrosion product film on the surface of L80Cr13 was mainly composed of Cr₂O₃ and Cr(OH)₃, which was locally damaged under the action of Cl^-, thereby, severe pitting corrosion emerged; the corrosion product film on the surface of L80 was mainly composed of FeS and FeCO₃, which has certain protective effect for the steel,thus the steel suffered from slight pitting corrosion. There is a passivation film formed only on the surface of steels 22Cr and 25Cr, while little pitting was detected.
