摘　　要：本文研究了VC的不同添加方式对WC-6%Ni(0.9%Cr 3 C 2)合金组织的影响,分别是在WC碳化阶段添加和在混合料球磨阶段添加。结果表明在混合料球磨阶段添加VC的样品烧结后表面出现麻面,实际是Ni聚集同时伴随Cr、V的偏析,另外在该样品内部也存在较多显微孔隙。In this paper the effects of addition method of VC on the microstructure of WC-6%Ni(Cr 3 C 20.9%)cemented carbide are researched.VC was added when WC was carbonized and mixture was grinded.The results show that,the sample’s surface are pitted when VC was added when the mixture was grinded.There are also microscopic pores in the interior of the sample.The reason is the aggregation of Ni,Cr,V.
