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。
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 cause of bug about ceramal in the process of cutting are analysed in this paper , and the methods of solutions are brought forth.
