THERMALLY STABLE POLYCRYSTALLINE DIAMOND WITH ENHANCED ATTACHMENT JOINT

摘要

The present disclosure relates to an industrial device, such as a drill bit including a thermally stable polycrystalline diamond (TSP) table coupled to a substrate via an attachment joint, with at least one attachment material located in the attachment joint. At least one of the attachment materials includes a metal or metal alloy and an additive material having a hardness higher than the metal or metal alloy or a coefficient of thermal expansion lower than that of the metal or metal alloy.
