Tungsten Carbide for Flame Spraying

The present invention provides a method for the manufacture of flame spraying of cobalt bonded tungsten carbide powder. Characterized in that:

1) Preparation of particles consisting essentially of -5 micron tungsten carbide powder having a first, a particle size of -44 +10 microns, a second tungsten carbide powder, the particle size of -5 microns and a particle size of the cobalt powder to 1 m carbon a powder mixture consisting of;

2) Ratio of the mixture was about 10 to 30% first tungsten carbide, 40 to 80% second tungsten carbide, 8 to 25% cobalt and 0.5 to 3% of carbon (a total of 100% by weight meter), and by compressing the mixture to produce a compressed product, the compressed product is sintered to produce a sintered product, crushing the sintered product to produce a crushed product, and classifying the pulverized product to produce the cobalt bonded tungsten carbide powder mixture to be processed.
