    摘要： A superhard polycrystalline construction comprises a body of polycrystalline superhard material formed of a mass of superhard grains exhibiting inter-granular bonding and defining a plurality of interstitial regions therebetween, and a non-superhard phase at least partially filling a plurality of the interstitial regions and having an associated shape factor of greater than around 0.65 and a substrate bonded to the body of superhard material along an interface, the substrate having a region adjacent the interface comprising hinder material in an amount at least 5% less than the remainder of the substrate.

    摘要： A polycrystalline super hard construction has a first region comprising a body of thermally stable polycrystalline super hard material having an exposed surface forming a working surface, and a peripheral side edge, said polycrystalline super hard material comprising a plurality of intergrown grains of super hard material; a second region forming a substrate to the first region, the second region comprising a hard phase and a binder phase; and a third region interposed between the first and second regions, the third region extending across a surface of the second region along an interface. The third region comprises a composite material having a first phase comprising a plurality of non-intergrown grains of super hard material, and a matrix material. The super hard polycrystalline construction further has a fourth region interposed between the second region and the third region, a major proportion of the fourth region comprising one or more components of the binder material of the second region, the fourth region further comprising one or more reaction products between the binder material of the second region and one or more components of the third region.

    摘要： A polycrystalline super hard construction is disclosed having a first region comprising a body of thermally stable polycrystalline super hard material having an exposed surface forming a working surface, and a peripheral side edge, the polycrystalline super hard material comprising a plurality of grains of super hard material; a second region forming a substrate to the first region; and a third region interposed between the first and second regions. The third region extends across a surface of the second region along an interface, the interface comprising a portion having an uneven topology and a substantially planar portion, the third region comprising a composite material including a first phase comprising a plurality of non-intergrown diamond grains, and a matrix material.

    摘要： A super hard polycrystalline construction is disclosed as comprising a first region comprising a body of thermally stable polycrystalline diamond material comprising a plurality of intergrown grains of diamond material; a second region forming a substrate to the first region; and a third region interposed between the first and second regions. The third region extends across a surface of the second region along an interface. The interface comprises at least a portion having an uneven topology, and the third region comprises a diamond composite material including a first phase comprising a plurality of non-intergrown super hard grains, said super hard grains comprising diamond grains; and a matrix material. The superhard material and matrix material of the third region form a diamond composite material which is more acid resistant than polycrystalline diamond material having a binder-catalyst phase comprising cobalt, and/or more acid resistant than cemented tungsten carbide material.
