나노 텅스텐 카바이드 재료 내 입성장 억제제와 코발트의 영향

Abstract

Influences of Co and inhibitors from nano-sized WC materials were observed in the sintering process. VC and Cr3C2 were used asinhibitors. The crystal structure and surface images of sintered nano-sized WC materials, as functions of Co and inhibitors, wereevaluated by XRD and FE-SEM analyses. The relative densities of sintered nano-sized WC materials did not change even withincreased quantity of Co and increased temperature. The density of sintered nano-sized WC materials with inhibitors was lower thanthat of sintered nano-sized WC materials without inhibitors. No difference in hardness due to change of inhibitors was found.
