METHOD OF PRODUCING DIAMOND COMPOSITE MATERIAL Russian patent published in 2012 - IPC B01J3/06 C01B31/06 C04B35/52 C04B35/645 B24D3/06 C22C26/00

Abstract RU 2446870 C1

FIELD: process engineering.

SUBSTANCE: proposed invention relates to production of diamond composite materials consisting of dense bulk of diamond crystals bonded by binder. Method comprises bringing layer of diamond powder and layer of binder in contact, subjecting them to pressure and heat and impregnating with binder of the following composition, in wt %: Si - 50÷70; Ni - 25÷45 and Ti - 3÷10. Compaction of diamond powder layer and impregnation with binder are performed at 2.0÷4.0 GPa and 1000÷300°C.

EFFECT: impregnation at lower pressure and temperature, high-strength and impact-resistant material.
