Superhard composite member and method of manufacturing the same
摘要
<p>A sintered body holding diamond grains in a matrix of cemented carbide or cermet in a dispersed state is obtained by direct resistance heating and pressurized sintering. The sintering is performed at a liquid phase generating temperature in a short time, so that the diamond grains are not directly bonded to each other. Thus, a superhard composite member which is excellent in hardness and wear resistance can be obtained without employing an ultra high-pressure vessel. <IMAGE></p>
