    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.

    Abstract: A degradation tool and a method of manufacturing the degradation tool is provided. The degradation tool (301) includes a holder body (302) to receive a support body (303) within a bore (304). A load transferring entity (306), such as a plurality of deformable balls, located at the base (305) of the bore (304) transfers load from the support body (303) to the holder body (302) during use, thereby preventing cracking at the base (305) of the support body (303).

    Abstract: A super hard construction comprises a substrate comprising a peripheral surface, an interface surface and a longitudinal axis extending in a plane and a super hard material layer formed over the substrate and having an exposed outer surface, a peripheral surface extending therefrom and an interface surface. One of the interface surface of the substrate or the interface surface of the super hard material layer comprises one or more projections arranged to project from the interface surface, the one or more projections being spaced from the peripheral surface of the substrate and a peripheral flange extending between the peripheral side edge and the interface surface. The peripheral flange is inclined at an angle of between around 5 degrees to around 30 degrees to a plane substantially perpendicular to the plane through which the longitudinal axis extends.

    Abstract: A capsule assembly for an ultra-high pressure furnace, comprising a containment tube having an interior side surface and defining a central longitudinal axis; a chamber suitable for accommodating a reaction assembly, a proximate and a distal end heater assembly, and a side heater assembly. When assembled, the chamber is contained within the containment tube and arranged longitudinally between the proximate and distal end heater assemblies. The side heater assembly is disposed adjacent the interior side surface and electrically connects the end heater assemblies with each other. Each end heater assembly has a respective peripheral side disposed adjacent the interior side surface. Heat is produced in the chamber in response to an electric current flowing through the end and side heater assemblies. At least a proximate side heater barrier spaces apart the side heater assembly from at least the proximate end heater assembly, adjacent its peripheral side, operative to prevent a portion of the side heater assembly from intruding between the peripheral side of the proximate end heater assembly and the containment tube and short-circuiting at least part of the proximate end heater assembly, when the end heater assemblies move towards each other in response to a force applied by the ultra-high pressure furnace onto the capsule assembly along the central longitudinal axis.
