摘要： Polycrystalline elements include a substrate and a polycrystalline table attached to an end of the substrate. The polycrystalline table includes a first region of superabrasive material having a first permeability and at least a second region of superabrasive material having a second, lesser permeability, the at least a second region being interposed between the substrate and the first region. Methods of forming a polycrystalline element involve attaching a polycrystalline table including a first region of superabrasive material having a first permeability and at least a second region of superabrasive material having a second, lesser permeability to an end of a substrate, the at least a second region being interposed between the first region and the substrate. Catalyst material is removed from at least the first region of the polycrystalline table.

摘要： Methods of forming a polycrystalline element comprise forming a polycrystalline table on a first substrate. Catalyst material may be removed from at least a portion of the polycrystalline table. The polycrystalline table and a portion of a first substrate attached to the polycrystalline table may be removed from a remainder of the first substrate. The portion of the first substrate may be attached to another substrate. Polycrystalline elements comprise a polycrystalline table attached to a portion of a first substrate on which the polycrystalline table was formed another substrate attached to the portion of the first substrate.

摘要： Methods of forming a polycrystalline table comprise disposing a plurality of particles comprising a superabrasive material, a substrate comprising a hard material, and a catalyst material in a mold. The plurality of particles is partially sintered in the presence of the catalyst material to form a brown polycrystalline table having a first permeability attached to an end of the substrate. The substrate is removed from the brown polycrystalline table and catalyst material is removed from the brown polycrystalline table. The brown polycrystalline table is then fully sintered to form a polycrystalline table having a reduced, second permeability. Intermediate structures formed during a process of attaching a polycrystalline table to a substrate comprise a substantially fully leached brown polycrystalline table. The substantially fully leached brown polycrystalline table comprises a plurality of interbonded grains of a superabrasive material.
