摘要

采用实验方法研究了暴露在北部湾潮间带的碳钢的腐蚀行为。设计Q235 CS试件并暴露12个月。通过扫描电子显微镜（SEM）、能谱仪（EDS）和X射线衍射仪（XRD）对CS的腐蚀机理进行了表征。结果表明，CS的腐蚀性能可以通过公式D来验证 = atn。腐蚀产物主要由α-FeOOH、γ-FeOOH.β-FeOOH-Fe3O4和γ-Fe2O3组成。值得注意的是，Cl–是腐蚀过程中的中间体，并促进特征产物β-FeOOH的形成。

Corrosion behaviour of carbon steel in Beibu Gulf tidal zone

ABSTRACT Corrosion behaviour of carbon steel (CS) exposed in the tidal zone of Beibu Gulf was investigated by experimental method. Q235 CS specimens were designed and exposed for 12 months. The corrosion mechanism of CS was characterised by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-Ray diffraction (XRD). Results show that the corrosion performance of CS can be verified by the formula D = atn . The corrosion products are mainly composed of α-FeOOH, γ-FeOOH, β-FeOOH, Fe3O4 and γ-Fe2O3. Significantly, Cl– is an intermediate in the corrosion process and promotes the formation of the characteristic product β-FeOOH.
