Abstract
A composite material is described which includes a mixture of individual diamond crystals and pieces of precemented carbide. The mixture is heated and pressurized to create intercrystalline bonds between the diamond crystals and chemical bonds between the diamond crystals and the precemented carbide pieces. The resulting composite polycrystalline diamond body exhibits excellent wear characteristics and impact resistance.
