ABSTRACT:
A polycrystalline diamond abrasive element, particularly a cutting element, comprises a layer of polycrystalline diamond having a working surface and bonded to a substrate, particularly a cemented carbide substrate, along an interface. The polycrystalline diamond abrasive element is characterized by using a binder phase that is homogeneously distributed through the polycrystalline diamond layer and that is of a fine scale. The polycrystalline diamond also has a region adjacent the working surface lean in catalyzing material and a region rich in catalyzing material.
