Wear resistance and longer working life; underlying tungsten cobalt carbide is generally

It's a different surface for diamond size powders sintered polycrystalline diamond, with a high hardness, wear resistance and longer working life; underlying generally cobalt tungsten carbide, it has good toughness, the surface layer of  polycrystalline diamond  diamond to provide good support, and easily welded by soldering to a variety of tools. At home and abroad are generally used method of manufacturing high  synthetic diamond powder  temperature sintering of polycrystalline diamond - carbide composite sheet fertilizer production line. Because of its use to expand the scope of its performance requirements increase, and thus the corresponding performance detection method has also been a rapid development process, the detection accuracy and effectiveness are mature.
