POLYCRYSTALLINE DIAMOND EQUIPPED WITH HIGH SURFACE IRREGULARPART AND PRODUCTION THEREOF

Japanese Patent JPS6020804

A

A polycrystalline diamond body with a plurality of faces having enhanced surface irregularities over at least a portion of at least one of the faces is disclosed. The polycrystalline diamond body with the enhanced surface irregularities attaches to other materials such as metal by conventional mounting techniques. The polycrystalline diamond bodies of this invention are without a carbide or metal backing. The pattern forming the enhanced surface irregularities of this invention can be predetermined or random. Similarly the pattern can be randomly distributed on the surface or positioned in a repeatable pattern. It is therefore not necessary that the surface irregularities be uniform in either shape or size. One method of forming the enhanced irregularities is during the press cycle during which the polycrystalline diamond is formed with screens, molds, or free standing bodies. The extent, form and location of the enhanced surface irregularities is controlled by the configuration of the screens, molds or free standing bodies. An alternative method to form enhanced surface irregularities in a polycrystalline diamond involves the use of an EDM machine, laser or other suitable techniques to form the anhanced irregularities after the polycrystalline diamond has been formed.
