Abstract
A method is shown for forming a diamond impregnated carbide containing dispersed diamond crystals, the crystals being formed via in-situ conversion of graphite to diamond. Graphite particles are blended with tungsten carbide power and a binder containing elemental powders known to be diamond catalyst. After blending, the powder is pressed into a green body of a desired shaped and sintered. After sintering, the body is loaded into a high temperature and pressure apparatus and exposed to conditions sufficient to convert the graphite to diamond.
