低碳钢暴露在海洋大气中会导致各种腐蚀产物的形成，主要是锂镁铁矿、针铁矿、磁铁矿和赤铁矿。本研究采用掠入射X射线衍射仪、显微X射线衍射仪和扫描电子显微镜/显微拉曼光谱仪对锈层表面进行了表征，并对锈层的主成分相及其形貌进行了鉴定。得出的主要结论是，锂辉石优先分布在钢的最外表面，而磁铁矿和蓝晶石则主要形成在靠近母材的表面。扫描电子显微镜/显微拉曼技术在表征(识别)锈相呈现的各种形貌方面非常有用。(C)2016爱思唯尔有限公司。保留所有权利。
The exposure of mild steel to marine atmospheres gives rise to the formation of various corrosion products, mainly lepidocrocite, goethite, magnetite and akaganeite. In this study, Grazing Incidence X-Ray Diffraction, Micro-X-Ray Diffraction and Scanning Electron Microscopy/Micro-Raman are used to characterise rust layer surfaces and to identify the principal component rust phases and their morphology. The main conclusion reached is that lepidocrocite is preferentially located on the outermost surface while magnetite and akaganeite form mostly close to base steel. The Scanning Electron Microscopy/Micro-Raman technique has been very useful for characterising (identifying) the wide variety of morphologies presented by the rust phases. (C) 2016 Elsevier Ltd.
