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 st.>P>l st., where P is value of pressure during packing, st. is strength of powder with greater strength, l st. is strength of powder with less strength. ^ EFFECT: lower labour input in production of the composite material. ^ 2 dwg |
