摘要:
Diamond bonded constructions comprise a polycrystalline diamond body having a matrix phase of bonded-together diamond grains and a plurality of interstitial regions between the diamond grains including a catalyst material used to form the diamond body disposed within the interstitial regions. A sintered thermally stable diamond element is disposed within and bonded to the diamond body, and is configured and positioned to form part of a working surface. The thermally stable diamond element is bonded to the polycrystalline diamond body, and a substrate is bonded to the polycrystalline diamond body. The thermally stable diamond element comprises a plurality of bonded-together diamond grains and interstitial regions, wherein the interstitial regions are substantially free of a catalyst material used to make or sinter the thermally stable diamond element. A barrier material may be disposed over or infiltrated into one or more surfaces of the thermally stable diamond element.
