Abstract

A superhard construction comprises a substrate and an ultra hard material layer formed over the substrate. One of the interface surface of the substrate or the interface surface of the ultra hard material layer comprises a plurality of spaced-apart projections arranged to project from the interface surface, the interface surface between the spaced-apart projections being uneven. A further superhard construction comprises a plurality of projections arranged to project from the interface surface which abut one or more adjacent projections along an edge thereof on the surface from which the projections project, and extend over all or a majority of the interface surface. One or more of the surfaces of all or a majority of the projections extend in one or more planes which are not substantially parallel to the plane of the exposed outer surface of the ultra hard material layer and/or in one or more planes which are not substantially parallel to a plane through which the central longitudinal axis of the substrate extends.
