FIELD: lubricants.
SUBSTANCE: lubricant combination for use in powder metallurgy is prepared by mixing selected first and second lubricants and placing resulting mix under conditions assisting sticking of the second lubricant particles to the first ones to form combination in the form of aggregated particles with its nuclei consisting of the first lubricant particles coated by the second ones. First lubricant is selected from fatty acid diamides and monoamides and the second from metal soaps. Average particle size of the first lubricant are preferably equal to at least 15 μm and that of the second lubricant up to 6 μm, all particles being spherical.
EFFECT: increased apparent density and flow velocity, improved uniformity in distribution of density in compacted part.
