FIELD: process engineering.
SUBSTANCE: invention relates to powder metallurgy, particularly, to materials intended for production of diamond-metallic composite materials. It may be used as hard or abrasive material and for making centrifuge nozzles. Diamond particles are mixed with those of metallic filler to produce mix for moulding billet therefrom. Said billet is subjected to pre-sintering by heating to ≤500°C and impregnated with one or more wetting elements or one or more wetting alloys. Impregnation is performed in vacuum or in inert gas at <200 bar.
EFFECT: higher density, thermal expansion, crack resistance and solderability.
