摘要

采用SHS-离心法在薄壁钢管内壁复合了一层厚度为2～3mm的陶瓷层。通过XRD、SEM、EDS手段分析了陶瓷层及其与钢管结合界面的组织结构。结果发现

陶瓷层由Al2O3、复合化合物和少量的残余Fe组成;陶瓷层与钢管之间存在着界面过渡层

过渡层的存在

有利于改善陶瓷与钢管之间的界面结合。

Abstract

Ceramic coating layer with 2～3 mm in thickness was obtained on surface of thin-walled steel pipe by SHS-centrifugal process.Microstructure of ceramic layer and interface between ceramics and steel pipe were analyzed by XRD （X-ray diffraction）

SEM （scanning electron microscope） and EDS.The results reveal that the ceramic coating is composed of Al2O3

complex compound and trace residual Fe.Interfacial transition layer between ceramic coating and steel pipe can be observed

which is beneficial for improving the interfacial bonding of ceramic coating with steel pipe.
