FIELD: powder metallurgy.
SUBSTANCE: invention relates to powder metallurgy, in particular to methods of manufacturing copper-based antifriction materials. It can be used to obtain parts for tribotechnical purposes subjected to plastic deformation for shaping. A base charge is poured into the mold layer by layer, containing wt.%: 4-8 tin, the rest is copper, and a charge of an antifriction layer based on copper with 8-10 wt.% tin at a ratio of the weight of the charge of the base layer to the weight of the charge of the antifriction layer (8 -10):1. Then the workpiece is pressed and sintered in a protective-reducing atmosphere.
EFFECT: invention provides high tribotechnical properties, ductility and strength.
