摘要:

通过湿/干循环实验 (在蒸馏水中润湿并在空气中干燥)、场发射扫描电子显微镜 (FE-SEM)、X射线衍射 (XRD)、电子探针 (EPMA) 和其他表面测试技术以及电化学阻抗谱 (EIS)，研究了690 MPa高强度贝氏体钢 (简称Q690钢) 在模拟乡村大气中的长期腐蚀行为。结果表明，在整个腐蚀过程中，Q690钢的腐蚀过程可以分为两个阶段，即加速阶段和减速阶段。在腐蚀的早期阶段，以板条贝氏体 (LB) 为主的Q690钢的耐蚀性优于含有铁素体 (F) 和珠光体 (P) 组织的Corten-A钢。在腐蚀后期，Q690钢锈垢中Cr的富集和α-FeOOH的增加增强了锈层的防护性，导致Q690钢的腐蚀速率降低，因此表明Q690钢耐腐蚀性能明显优于Corten-A钢。

Abstract：

The long-term corrosion behavior of 690 MPa high-strength bridge steel (referred as Q690 steel) in a simulated rural atmosphere was investigated via wet/dry cyclic test with wetting in distilled water and drying in air, as well as electrochemical impedance spectroscopy (EIS), field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), electron probe (EPMA) and other surface testing techniques. The results indicate that the corrosion process of Q690 steel can be differentiated as two stages during the whole corrosion process, namely the accelerated and the decelerated stages. In the early stage of corrosion, the corrosion resistance of Q690 steel with microstructure of lath bainite (LB) is better than that of Corten-A steel with microstructure of ferrite (F) and pearlite (P). In the later stage of corrosion, the enrichment of Cr element and the increase of α-FeOOH in the rust scale of Q690 steel have enhanced the protectiveness of the rust scale, leading to the decrease of the corrosion rate of Q690 steel, hence which shows significantly better corrosion resistance than the Corten-A steel.
