摘要
A cobalt bonded tungsten carbide powder is produced by a method comprising preparing a mixture consisting of a first tungsten carbide powder having a particle size of -5 microns, a second tungsten carbide powder having a particle size of -44+10 microns, a cobalt powder having a particle size of -5 microns and a carbon powder having a particle size of -1 micron. The mixture has proportions, by weight totaling 100%, of about 10% to 30% first tungsten carbide, 40% to 80% second tungsten carbide, 8% to 25% cobalt and 0.5 to 3% carbon. The mixture is processed by compacting, sintering, crushing, and classifying to produce the cobalt bonded tungsten powder in a size range -100+10 microns.
