Beschreibung
Zusammenfassung:FIELD: production of new composite materials, superhard composite materials inclusive. ^ SUBSTANCE: proposed method includes molding the blanks from borazon powders followed by heat treatment of blanks in hydrocarbon medium and impregnation with liquid silicon at temperature of 1420-1700°C and pressure no less than 1000 mm Hg. Heat treatment in hydrocarbon medium is continued till increase of mass of blank by 3-25%. Borazon grains are bonded by silicon carbide matrix; proposed method excludes losses of superhard materials in forming silicon carbide due to diamond. ^ EFFECT: enhanced efficiency; enhanced controllability of properties of materials. ^ 4 ex
