TUNGSTEN CARBIDE-CUBIC BORON NITRIDE COMPOSITE MATERIAL AND PREPARATION METHOD THEREOF

ZHANG JIANFENG / WU YUPING / HONG SHENG / LI GAIYE / GUO WENMIN

A tungsten carbide-cubic boron nitride composite material and preparation method thereof mainly includes WC and cBN, wherein the WC powder is coated with Co nano-layer and the cBN powder is coated with SiO2 nano-layer, and hardness and toughness of the composition material can be improved by coating. The method for preparing a tungsten carbide-cubic boron nitride composite material adopts chemical vapor deposition method and high temperature sintering method. First nano-layers were coated on the surface of WC and cBN, and then the bulk materials can be obtained via high-temperature sintering.
