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.

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： Cutting elements for earth-boring tools may generate a shear lip at a wear scar thereon during cutting. A diamond table may exhibit a relatively high wear resistance, and an edge of the diamond table may be chamfered, the combination of which may result in the formation of a shear lip. Cutting elements may comprise multi-layer diamond tables that result in the formation of a shear lip during cutting. Earth-boring tools include such cutting elements. Methods of forming cutting elements may include selectively designing and configuring the cutting elements to form a shear lip. Methods of cutting a formation using an earth-boring tool include cutting the formation with a cutting element on the tool, and generating a shear lip at a wear scar on the cutting element. The cutting element may be configured such that the shear lip comprises diamond material of the cutting element.

摘要： An earth-boring bit has a mechanical face seal assembly with PCD faces. The bit has a bearing shaft with a cone rotatably mounted on the bearing shaft. The seal locates between the bearing shaft and the cone for sealing lubricant therein. The seal includes at least one rigid seal ring having a cemented carbide body and an annular PCD face located on it. The mating face may also be of a PCD material. The cemented carbide body contains a binder that migrates into the PCD face while the PCD face is being formed. A binder-free region is leached on the surface of the PCD face.

摘要： A cutter for a drill bit has a superabrasive member joined to a substrate at a three-dimensional interface. The three-dimensional interface comprises a protrusive pattern of interconnected elements comprising projections of the superabrasive member into the substrate and vice versa. The protrusive pattern comprises at least one generally annular member intersected by a series of generally radially extending members for distributing stresses along the interface, enhancing compressive strength, and enabling optimization of the magnitudes and locations of beneficial residual stresses in the superabrasive member and in the vicinity of the substrate.

摘要： An array of chisel-shaped cutting elements are mounted to the face of a fixed cutter bit. Each cutting element has a crest and an axis which is inclined relative to the borehole bottom. The cutting elements have a hardened diamond exterior on all surfaces in contact with the formation. The chisel-shaped cutting elements may be arranged on a selected portion of the bit, such as the center of the bit, or across the entire cutting surface. In addition, the crest on the cutting elements may be oriented generally parallel or perpendicular to the borehole bottom. The chisel shape and crest orientation increase the initial contact area while reducing aggressiveness. These advantages are achieved without increasing cutter density, reducing back rake, or adding depth of cut limiters. Chisel-shaped cutting elements having crests which are oriented perpendicular to the borehole bottom have the added advantage of displacing the material in a plane that is parallel to the bit face. This reduces the likelihood of harmful bit balling, particularly on heavy set bits with small open face volume.

摘要翻译： 凿子切割元件阵列安装在固定刀头的表面上。 每个切割元件具有相对于钻孔底部倾斜的波峰和轴。 切割元件在与地层接触的所有表面上具有硬化的金刚石外观。 凿子形切割元件可以布置在钻头的选定部分上，例如钻头的中心，或跨越整个切割表面。 此外，切割元件上的波峰可以大致平行或垂直于钻孔底部定向。 凿子形状和波峰方向增加了初始接触面积，同时降低了攻击性。 这些优点在不增加刀具密度，减少后刀尖或增加切削限制器的深度的情况下实现。 具有垂直于钻孔底部定向的波峰的凿状切割元件具有在平行于钻头面的平面内移动材料的附加优点。 这样可以减少有害钻孔的可能性，特别是在打开面积小的重型钻头上。
