Superabrasive tool with metal mesh stress stabilizer between superabrasive and substrate layers
A multi-layer polycrystalline superabrasive PCD or PCBN blank for attachment to a working tool is disclosed. The blank comprises an abrasive layer of PCD or PCBN and a substrate layer of cobalt containing cemented tungsten carbide. In between the abrasive and substrate layers is a metal mesh stabilizer layer sintered by HPHT to the abrasive and substrate layers. The apertures of the mesh layer contain PCD or PCBN which, along with the mesh are sintered to the support and substrate layers and cobalt present in the substrate layer is infiltrated through the mesh layer into the abrasive layer as a binder. The metal mesh layer provides stability to the abrasive and substrate layers which have different stress and thermal expansion properties.
