研究了W18Cr4V高速钢表面TiC－Co金属陶瓷熔覆层的组织及其与基体间的界面组织特征，熔覆层的组织特征为在灰色共晶组织上分布着大量的TiC颗粒，与基体形成了良好的冶金结合。在熔覆过程中TiC部分熔化，而Co则全部熔化，且有一定的烧损。熔覆层硬度较高，可达1682HV0.1。Ni基合金过渡底层的采用．可以在较宽的工艺范围内得到均匀连续且为冶金结合的金属陶瓷激光溶覆层，涂层最高硬度为1193HV0.1。
The microstructure and interfacial microstructure of the TiC-Co cermet cladding layer on W18Cr4V high speed steel were studied. The microstructure of the cladding layer was characterized by a large amount of TiC particles distributed on the gray eutectic and formed with the matrix Good metallurgical bonding. In the cladding process, TiC partially melts, while Co is all melted and has some burning loss. Cladding the higher hardness, up to 1682HV0.1. Ni-based alloy transitional bottom of the adoption. Can be a wide range of uniform and continuous metallurgical laser metallurgical coating, the maximum hardness of the coating 1193HV0.1.
