The study of co-doped NbC / Cr3C2 on the application of ultrafine WC-10%Co cemented carbides
In this paper, ultrafine WC-10%Co cemented carbides were prepared by vacuum sintering.For inhibition of growth of WC grains during sintering, NbC and Cr3C2 were used as inhibitors.With the transformation of co-doped inhibitors content, the grain growth is inhibited and the grain size achieves 490 nm at 0.4% Cr3C2 / 0.3% NbC.The mechanism that co-doped NbC / Cr3C2 on the effective reduction of ultrafine WC-10%Co cemented carbides was analyzed.The 0.4% Cr3C2 / 0.3% NbC addition equipped with the best integrated mechanical properties was obtained in this study.And sintered samples were investigated with scanning and transmission electron microscopy (SEM).
