METHOD FOR MANUFACTURE OF COMPOSITE PRODUCTS ON DISPERSION MATRIX Russian patent published in 1995 - IPC

FIELD: powder metallurgy, in particular, production of diamond tools. SUBSTANCE: method involves providing die and placing groups of dispersion particles of different composition into die; pressing and heating to minimum temperature of a range of melting temperatures of at least one group of particles positioned in plane of conjugation between die and/or insertion members and dispersion matrix filling the die, with volume content of groups of particles with minimum melting temperature making 30-50% of the total volume and wetting angle exceeding 90. EFFECT: increased efficiency and improved quality of products. 7 cl, 1 tbl
