PCD refers to diamond particles which have been sintered together with a binder phase under high-pressure, high-temperature condition similar to those used in single crystal diamond synthesis.
1,These sintered PCD materials have a variety of uses, most notably for cutting tools machining non-ferrous metals and non-metallic materials and for wear parts. An advantage of these materials is that their structure and composition can be engineered to have properties tailored to specific applications and opertiona.
2,As a cutting tool material, PCD is generally recommended for the machining of non ferrous work-piece materials where high abrasion resistance is required. Examples of typical work piece materials are as follows:
Metal matrix composite ,silicon aluminum alloys, copper, ceramics, fiber glass, carbon fiber reinforced plastics, rubber, pre-sintered and sintered tungsten carbide.
