Title: SUPERHARD CONSTRUCTIONS & METHODS OF MAKING SAME
Abstract:
A method of forming a super hard polycrystalline construction is disclosed as comprising placing a pre-formed structure of a first material into a canister, introducing a plurality of grains or particles of super hard material into the canister to locate the grains or particles in and/or around the pre-formed structure to form a pre-sinter assembly and treating the pre-sinter assembly at an ultra-high pressure of around 5 GPa or greater and a temperature to sinter together the grains of super hard material in the presence of a binder material to form the super hard polycrystalline construction comprising a body of polycrystalline super hard material having a first region of super hard grains in a binder material, and an embedded second region.
