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.

摘要： Ultra-hard constructions comprise polycrystalline diamond-body having a first metallic substrate attached thereto, and having a second metallic substrate attached to the first metallic substrate. The first and second substrates each comprise a first hard particle phase, e.g., WC, and a second binder material phase, e.g., Co, wherein the hard particles in the second substrate are sized larger than those in the first substrate. The first substrate may contain a larger amount of binder material than the second substrate. Constructed in this matter, the first substrate is engineered to facilitate sintering diamond body during HPHT conditions, while the second substrate is engineered to provide an improved degree of erosion resistance when placed in an end-use application. The construction may be formed during a single HPHT process. The second substrate may comprise 80 percent or more of the combined thickness of the first and second substrates.
