摘要： A cutting element for use with an earth-boring drill bit includes a diamond cutting table that is substantially free of a metallic binder. The cutting table may include polycrystalline diamond and a carbonate binder or polycrystalline diamond with silicon and/or silicon carbide dispersed therethrough. A base of the cutting table is secured to a substrate by way of an adhesion layer. The adhesion layer includes diamond. The adhesion layer may also include cobalt or another suitable binder material, which may be mixed with diamond particles from which the adhesion layer is formed, or may leach from the substrate into the adhesion layer as the cutting element is bonded to the substrate. Alternatively, the cutting table may be formed from and consist essentially of chemical vapor deposited diamond that has been diamond bonded to an underlying polycrystalline diamond compact. Processes may include securing substantially metallic binder-free cutting elements to substrates.

摘要： Cutting elements for use in earth-boring applications include a substrate, a transition layer, and a working layer. The transition layer and the working layer comprise a continuous matrix phase and a discontinuous diamond phase dispersed throughout the matrix phase. The concentration of diamond in the working layer is higher than in the transition layer. Earth-boring tools include at least one such cutting element. Methods of making cutting elements and earth-boring tools include mixing diamond crystals with matrix particles to form a mixture. The mixture is formulated in such a manner as to cause the diamond crystals to comprise about 50% or more by volume of the solid matter in the mixture. The mixture is sintered to form a working layer of a cutting element that is at least substantially free of polycrystalline diamond material and that includes the diamond crystals dispersed within a continuous matrix phase formed from the matrix particles.
