摘要： Low coefficient of thermal expansion (CTE) cermet compositions of this invention generally comprise a hard phase material and a ductile phase formed from a binder alloy, wherein the binder alloy is specially designed having a CTE that is closely matched to the hard phase material. Hard phase materials used to form low CTE compositions of this invention are selected from the group of carbides consisting of W, Ti, Mo, Nb, V, Si, Hf, Ta, and Cr carbides. The binder alloy is formed from a mixture of metals selected from the group consisting of Co, Ni, Fe, W, Mo, Ti, Ta, V, Nb, C, B, Cr, and Mn. In a preferred embodiment, low CTE compositions comprises WC as the hard phase material, and a ductile phase binder alloy formed from a mixture of Fe, Co, and Ni. The so-formed low CTE composition has a coefficient of thermal expansion that is less than that of conventional WC—Co at the same temperature and having the same metal content, thereby providing improved resistance to thermal shock and thermal fatigue related failure.

摘要： Polycrystalline diamond constructions include a diamond body comprising a matrix phase of bonded together diamond crystals formed at high pressure/high temperature conditions with a catalyst material. The sintered body is treated to remove the catalyst material disposed within interstitial regions, rendering it substantially free of the catalyst material used to initially sinter the body. Accelerating techniques can be used to remove the catalyst material. The body includes an infiltrant material disposed within interstitial regions in a first region of the construction. The body includes a second region adjacent the working surface and that is substantially free of the infiltrant material. The infiltrant material can be a Group VIII material not used to initially sinter the diamond body. A metallic substrate is attached to the diamond body, and can be the same or different from a substrate used as a source of the catalyst material used to initially sinter the diamond body.

摘要： PCD constructions include a PCD body comprising a polycrystalline matrix region, a first region that includes a replacement material positioned remote from a body surface, and a second region that is substantially free of the replacement material and that extends a depth from the body surface. The PCD construction can further include a substrate that is attached to the body. The PCD body is formed by removing a solvent catalyst material used to form the body, replacing the removed solvent catalyst material with a replacement material, and then removing the replacement material from a region of the body to thereby form the second region. The replacement material can be introduced into the PCD body during a HPHT process, and the substrate may or may not be the source of the noncatalyzing material.

摘要： A bit body formed of a mixture of matrix material and superabrasive powder and including pockets lined with superabrasive-free matrix material, and a method for forming the same, are provided. The pockets are shaped to receive cutting elements therein. The superabrasive-free matrix material enhances braze strength when a cutting element is brazed to surfaces of the pocket. The method for forming the drill bit body includes providing a mold and displacements. The displacements are coated with a mixture of superabrasive free matrix-material and an organic binder. The mold is packed with a mixture of matrix material and superabrasive powder and the arrangement heated to form a solid drill bit body. When the solid bit body is removed from the mold, pockets are formed by the displacements in the bit body and are lined with the layer of superabrasive-free matrix material. The superabrasive material may be diamond, polycrystalline cubic boron nitride, SiC or TiB2 in exemplary embodiments.
