Abstract

A cutting element comprises a multilayer polycrystalline diamond element 42 bonded to a substrate 44 of a less hard material, the polycrystalline diamond element 42 defining a matrix of interstitial volumes, the interstitial volumes of a first region of the diamond layer 42 adjacent a working surface 46 thereof being substantially free of a catalysing material, the interstitial volumes of a second region of the diamond layer 42 remote from the working surface 46 containing catalysing material.

Description

cutting element field of invention The present invention relates to a cutting element, and more particularly to a cutting element suitable for use in a drill bit for forming a borehole. Background technique One type of cutting element used on a drill bit consists of a series of superhard materials, such as polycrystalline diamond, bonded to a substrate of a lower hardness material, such as tungsten carbide. Cutting elements of this type are well known and are used in a range of shapes and sizes and in a range of applications. Cutting elements of the type described are manufactured through a high temperature, high pressure process in which portions of the tungsten carbide substrate, diamond powder, and bonded catalyst (e.g. in the form of cobalt) are exposed to high temperature, high pressure conditions resulting in diamond crystals in the diamond powder A chemical bond is formed between them, forming a polycrystalline diamond layer that is also partially bonded to the su...
