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 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.

摘要： Methods of forming cutting elements for earth-boring tools include providing a barrier material between a first powder and a second powder each comprising diamond grains, and subjecting the powders and barrier material to high temperature and high pressure conditions to form polycrystalline diamond material. The formation of the polycrystalline diamond material is catalyzed, and catalytic material may be hindered from migrating across the layer of barrier material. Cutting elements for use in earth-boring tools include a barrier material disposed between a first layer of polycrystalline diamond material and a second layer of polycrystalline diamond material. Earth-boring tools include one or more such cutting elements for cutting an earth formation.

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 for securing substantially metallic binder-free cutting elements to substrates are also disclosed.

摘要： An abrasive-impregnated cutting structure for use in drilling a subterranean formation is disclosed. The abrasive-impregnated cutting structure may comprise a plurality of abrasive particles dispersed within a substantially continuous matrix, wherein the abrasive-impregnated cutting structure exhibits an anisotropic wear resistance. One or more of the amount, average size, composition, properties, shape, quality, strength, and concentration of the abrasive particles may vary within the abrasive-impregnated cutting structure. Anisotropic wear resistance may relate to a selected direction, such as, for example, one or more of an expected direction of engagement of the abrasive-impregnated cutting structure with the subterranean formation and an anticipated wear direction. Anisotropic wear resistance of an abrasive-impregnated cutting structure may be configured for forming or retaining a formation-engaging leading edge thereof. A rotary drag bit including at least one abrasive-impregnated cutting structure is disclosed.
