ABSTRACT:
A compact blank for use in operations that require improved thermal stability, impact strength, and abrasion resistance is disclosed. The compact includes a substrate formed of tungsten carbide or other hard material with multiple abrasive diamond crystal layers bonded to the substrate. The abrasive diamond crystals are provided in successive layers of different size particles with the coarsest size particles being farthest away from the substrate. A catalyst is premixed with the diamond crystals in a weight percent which progressively decreases from the layer closest to the substrate through succeeding layers.
