FIELD: process engineering.
SUBSTANCE: invention relates to production of carbon-based superhard composite to be used for making tools for mining, stone-working and metal working. Proposed method comprises applying high pressure and temperature to initial carbon component, a diamond, and binder. Note here that said carbon component comprises additionally fullerene and/or nanodiamond while said binder represents one or several components selected from the family including silicon bronze alloy, Monel metal, solid alloy. Superhard material is produced in two steps. At first step, the mix of initial components is subjected to dynamic pressure of 10-50 GPa at 900-2000°C. At second step, obtained material is placed in high-pressure vessel and subjected to static pressure of 5-15 GPa and heated to 700-1700°C for at least 20 seconds.
EFFECT: superhard micro hardness, high modulus of elasticity and higher wear resistance.
