摘要： Cutting elements include a diamond-bonded body attached with a substrate. The substrate has a coercivity of greater than about 200 Oe, and has a magnetic saturation of from about 73 to 90. The diamond-bonded body has a compressive stress at the surface of greater than about 0.9 GPa after heat treatment, and greater than about 1.2 GPa prior to heat treatment.

摘要： A cutting element may be formed by sintering together a plurality of metal carbide grains and a metal binder to form a substrate, forming at least one binder gradient in the substrate, and mounting an abrasive layer to the substrate at an interface. The concentration of metal binder material may decrease along at least one direction to form the at least one binder gradient.

摘要： A method of making a polycrystalline diamond compact includes forming multiple layers of premixed diamond particles and carbonate material, where the carbonate material includes an alkaline earth metal carbonate, and where each layer has a weight percent ratio of diamond to carbonate that is different from adjacent layers. The layers are subjected to high pressure high temperature conditions to form polycrystalline diamond.
