Tungsten carbide-cubic boron nitride composite material and preparation method thereof

摘要

A method of preparing tungsten carbide-cubic boron nitride composite material, employing chemical vapor deposition and high temperature sintering: first, respectively coating WC and cBN surfaces with nanoparticle layers, and then sintering at a high temperature to obtain bulk material. The produced tungsten carbide-cubic boron nitride composite material has characteristics of high structural thermostability, high hardness and the like, and can serve as the material for high-speed cutting blades.
