Abstract: Superabrasive compacts and methods of making superabrasive compacts are disclosed. A superabrasive compact includes a polycrystalline diamond table and a substrate attached to the polycrystalline diamond table. The substrate includes a hard metal carbide and a binder having a compound with a composition of AxByCz, where A and B are transition metals, where C is carbon, and where 0≤x≤7, 0≤y≤7, x+y=7, and 0≤z≤3.

Abstract: A superabrasive compact and a method of making the superabrasive compact are disclosed. A superabrasive compact may comprise a diamond table and a substrate. The diamond table may be attached to the substrate. The diamond table may include bonded diamond grains defining interstitial channels. The interstitial channels may be filled with non-binder materials in the first region. The interstitial channels in the second region may be filled with a binder material and an additive from the substrate.
