  • Publication number: 20230202847
    Abstract: 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.

  • Patent number: 11565317
    Abstract: A polycrystalline super hard construction has a first region having a body of thermally stable polycrystalline super hard material having a plurality of intergrown grains of super hard material; a second region forming a substrate having a hard phase and a binder phase; and a third region interposed between the first and second regions. The third region includes a composite material having a first phase comprising a plurality of non-intergrown grains of super hard material, and a matrix material. A fourth region interposed between the second and third region has a major proportion having one or more components of the binder material of the second region, and one or more reaction products between the binder material of the second region and one or more components of the third region.

  • Publication number: 20230012341
    Abstract: A polycrystalline diamond construction has a body of polycrystalline diamond (PCD) material; and a cemented carbide substrate bonded to the body of polycrystalline material along an interface. The cemented carbide substrate has tungsten carbide particles bonded together by a binder material, the binder material comprising Co; and the tungsten carbide particles form at least around 70 weight percent and at most around 95 weight percent of the substrate. The cemented carbide substrate has a bulk volume, the bulk volume of the cemented carbide substrate having at least around 0.1 vol. % of inclusions of free carbon having a largest average size in any one or more dimensions of less than around 40 microns.
