Abstract
A super hard polycrystalline construction comprises a body of polycrystalline super hard material, said body having an exposed working surface, a substrate attached to the body of polycrystalline super hard material along an interface and a plurality of apertures or channels. One or more of said apertures or channels extend(s) from the exposed working surface of the body into the substrate.
Claims17
A super hard polycrystalline construction comprising:
- a body of polycrystalline super hard material, said body having an exposed working surface, said body comprising inter-bonded super hard grains comprising natural and/or synthetic diamond grains, the super hard polycrystalline construction forming a polycrystalline diamond (PCD) construction;
- a substrate attached to the body of polycrystalline super hard material along an interface;
- and
- a plurality of apertures or channels, one or more of said apertures or channels extending from the exposed working surface of the body into the substrate;
- wherein:
- the PCD construction further comprises a non-super hard phase comprising a binder phase located in interstitial spaces between the inter-bonded diamond grains.
