FIELD: chemistry.
SUBSTANCE: invention refers to manufacturing of polycrystalline materials, which can be used, preferentially for producing drilling and dressing tools. A polycrystalline diamond composite with a dispersion-strengthened additive contains a refractory metal coating 0.02-0.15 mm thick containing diamond powder and metals with the metal presented by nickel, cobalt, whereas the dispersion-strengthened additive is tungsten carbide nanopowder in the following proportions, wt %: diamond - 85-90, nickel - 7-9, cobalt - 2-4, tungsten carbide nanopowder - 0.1-3.0.
EFFECT: technical effect consists in increasing the strength and wear resistance of the sintered composite, and selecting the high-melting coating ensures the reliable attachment of the material in the drilling tool.
