摘要： A composite material is disclosed along with the method of making the same. The material comprises a tough grade of cemented carbide granule dispersed with a hard brittle grade of cemented carbide granules to form a matrix. The quantity of hard, brittle cemented carbide granules is between 20% to 60% of the total composition. Such material functions to improve wear resistance without sacrificing toughness.

摘要： A hard facing rod is made by mixing particles of tungsten carbide, particles of a metal binder, and a temporary organic binder. The mixture is pressed, preferably by extrusion, into the form of a rod. The organic binder is removed and the rod is heated to a sufficient temperature to sinter the metal particles together without melting so that the rod has a residual porosity in the range of from 5 to 20%. Such a rod is used for hard facing a metal surface in lieu of conventional tube-rods. The technique permits a high proportion of tungsten carbide relative to the metal matrix and provides uniform distribution of carbide particles in the hard facing.
