Abstract
A method for making a polycrystalline diamond construction is disclosed, which includes the steps of treating a polycrystalline diamond body having a plurality of bonded together diamond crystals and a solvent catalyst material to remove the solvent catalyst material therefrom, wherein the solvent catalyst material is disposed within interstitial regions between the bonded together diamond crystals, replacing the removed solvent catalyst material with a replacement material, and treating the body having the replacement material to remove substantially all of the replacement material from a first region of the body extending a depth from a body surface, and allowing the remaining amount of the replacement material to reside in a second region of the body that is remote from the surface.
