The composition, microstructure, and hardness of the ceramal layer were analysed with the help of EPMA, XRD and a microhardness measuring instrument.
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。
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.
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。
