CHARGE FOR PRODUCTION OF COMPOSITE METAL-DIAMOND MATERIAL Russian patent published in 2010 - IPC B22F1/00 C22C1/05 C22C26/00 

FIELD: technological processes.

SUBSTANCE: invention relates to powder metallurgy, in particular to composite baked metal-diamond materials. Charge for manufacturing of composite metal-diamond material comprises 30-90 wt % of diamond nanocrystals and 10-70 wt % of nickel and aluminium mixture in stoichiometric ratio, which corresponds to Ni₃Al or NiAl; or 10-50 wt % of nickel and aluminium mixture in stoichiometric ratio, which corresponds to Ni₃Al or NiAl; and 50-90 wt % of diamond nanocrystals mixture with 10-40 wt % of aluminium over stoichiometry; or 5-70 wt % of aluminium and 30-95 wt % of diamond nanocrystals.

EFFECT: charge makes it possible to produce material having high strength, hardness, with stable lattice of diamond and surface of diamond particles cleaned from admixtures.
