    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.

    Abstract: A method for forming a polycrystalline diamond compact (PDC) includes treating a carbide substrate having a cobalt content therein with an acid, e.g., aqua regia, to remove cobalt from a surface portion of the carbide substrate; disposing diamond crystals on the treated carbide substrate; disposing a sweep material on the diamond crystals on a surface of the diamond opposite the carbide substrate; and applying high temperature and pressure to the carbide substrate, the diamond crystals and the sweep material such that the diamond crystals are sintered into a polycrystalline diamond attached to the carbide substrate to form the polycrystalline diamond compact.
