| Popis: | The sintering of a diamond composite from diamond and tungsten powders of submicron and nanosizes at high pressure and temperature has been discussed. It has been shown that as a result of the diamond and tungsten interaction tungsten carbide particles, which are chemically bonded to diamond particles, form in spaces between them. Over the whole volume of the composite the structure has been observed, where tungsten carbide and diamond grains are regularly placed and are uniform in size. An addition of a coarse diamond component to the composite has been found to contribute to an increase of the composite wear resistance. The optimal sintering parameters and formulation of this composite have been defined. |
