摘要
采用双层预涂覆方法在低碳钢表面激光熔覆金属陶瓷涂层。借助 EPMA,XRD和显微硬度计测定了熔覆涂层的化学成份、显微组织和显微硬度。结果表明, 金属陶瓷涂层具有更均匀的显微组织和高的硬度, 没有孔洞及裂纹产生。
Abstract
The ceramal layer on the surface of mild steel was cladded by using a double-layer precoating method. The composition, microstructure, and hardness of the ceramal layer were analysed with the help of EPMA, XRD and a microhardness measuring instrument. The results show that a more uniform microstructure and higher hardness were obtained in the ceramal layer, and there are no porosities and cracks in it.
