Abstract:
A method of forming a diamond compact includes adding an additive material to a tungsten carbide substrate, the additive material including a transition metal carbide other than tungsten carbide, placing a diamond body adjacent to an interface surface of the tungsten carbide substrate, and subjecting the diamond body and the tungsten carbide substrate to a high pressure high temperature bonding process to bond the diamond body to the tungsten carbide substrate.
