METHOD OF PRODUCING METAL COMPOSITE MATERIALS Russian patent published in 1999 - IPC

FIELD: production of metal composite materials. SUBSTANCE: method of producing solid composite materials coasted at least with one metal of iron group includes dissociation and complex binding of at least one salt of at least one metal of iron group containing organic groups in at least one polar solvent with at least one complexing agent containing functional groups in the form of OH or NR₃, (R = H or alkyl); addition to solution of solid forming powder; evaporation of solvent; heat treatment of remaining powder in inert and/or reducing atmosphere to produce the solid composite material coated with at least one solid metal of iron group. Added together with the powder to solution are water-soluble carbon source and thickener. As a result, powder with coating is produced and it may be thickened and sintered into material after addition of thickener. The material contains solid forming members in binding phase. EFFECT: higher efficiency. 2 cl, 3 dwg
