60SD 308/11/14 BRAZED THERMALLY-STABLE POLYCRYSTALLINE DIAMOND COMPACT WORKPIECES AND THEIR FABRICATION ABSTRACT OF THE DISCLOSURE Disclosed is a brazed implement comprising a thermally-stable polycrystalline diamond compact, e.g. a compact of self-bonded diamond particles having a network of inter-connected empty pores dispersed throughout the compact, bonded to another of said compact or bonded to a cemented carbide support by a brazing filler metal disposed therebetween. The brazing metal comprises an alloy having a liquidus above about 700°C and containing an effective amount of chromium. Translational shear strengths exceed about 50 kpsi even upon furnace cycling of the brazed implements and often exceed 90 kpsi. The method for fabricating the brazed implement also is disclosed.
