集装箱钢板在湿热海洋大气环境中的腐蚀行为
|
摘要
研究了集装箱钢板在西沙海洋大气环境中暴露不同阶段的腐蚀行为。采用SEM(EDS)、XRD研究了锈层形貌及成分,采用极化曲线研究了暴露不同阶段的腐蚀电化学行为。通过腐蚀深度测试,建立了腐蚀速率与暴露时间的幂指数关系,结合腐蚀形貌和产物分析,主要的锈蚀产物为γ-FeOOH、β-FeOOH。Cr和Cu合金元素也参与了锈层的形成,有助于提高锈层的致密性。电化学测试结果表明,耐候钢暴露不同阶段的腐蚀电流,3个月时值最低,6个月随后暴露时间增加,锈层不断增厚,起到对Cl~-的阻碍作用,降低腐蚀速率;之后随着暴露时间的增加,锈层出现脱落,腐蚀速率随之增加。
The corrosion behavior of container steel plates exposed to the marine atmosphere of the Xisha islands in different stages was investigated. The morphology and composition of the rust layer were studied by SEM(EDS) and XRD, and the electrochemical corrosion behavior was investigated using polarization curves in different exposure stages. Through the test of corrosion depth, an exponential relationship between the corrosion rate and exposure time was established. In combination with corrosion morphology and product analysis, the main rust products are γ-FeOOH and β-FeOOH. Cr and Cu alloying elements also contribute to the formation of a rust layer, which is conducive to improving the compactness of the rust layer. Electrochemical results show that for the container steel plates in different exposure stages, the corrosion current exposed for 3 months is the lowest; and with the exposure time increasing to 6 months, the rust layer continues to thicken, which hinders Cl~- ion and then reduces the corrosion rate. Then, the rust layer fell off and the corrosion rate increases as the exposure time increases.
