ABSTRACT:
A composite compact component made of a composite compact consisting of a diamond or BN powder bonded to a hard sintered alloy base during a sintering operation, and a substrate composed of steel or a hard sintered alloy bonded to the base of the composite compact through a high strength filler metal or alloy having a melting point of at least the liquidus point of the hard sintered alloy base. A process of making set composite compact component is also disclosed as well as a drill bit containing said composite compact component and variations thereof.
