METHOD OF OBTAINING COMPOSITE MATERIAL BASED ON DIAMOND AND/OR CUBIC BORON NITRIDE POWDER Russian patent published in 2010 - IPC C04B35/5831 

FIELD: chemistry.

SUBSTANCE: invention relates to mechanical engineering and particularly to obtaining composite materials based on diamond and/or cubic boron nitride powder, which can be used, for instance as cutting elements in different instruments: drilling, driving instruments, in stone working instruments and instruments used in building industry etc. The method of obtaining composite material involves putting diamond and/or cubic nitride powder into a mould, packing and saturation with metals and/or alloys. The diamond and/or cubic nitride powder with different strength is used and packing is carried out at pressure whose value is selected from the condition Σ_st.>P>Σ_{l st.}, where P is value of pressure during packing, Σ_st. is strength of powder with greater strength, Σ_{l st.} is strength of powder with less strength.

EFFECT: lower labour input in production of the composite material.
