Polycrystalline diamond carbide high wear resistance than

In polycrystalline diamond or polycrystalline diamond compact drill bit as cutting tools. It was in the 1980s emergence of new drill bit. Since polycrystalline  Diamond blade  high wear resistance than one to two orders of magnitude, than the natural diamond abrasion  cubic boron nitride  even higher, expanding the use of cutting broken in oil drilling, geological exploration core drilling to get application, has a very broad prospects.
