FIELD: powder metallurgy, namely manufacture of complex-profile sintered articles, possibly for making working organs of submerged pumps and so on.
SUBSTANCE: method comprises steps of separately pressing members of article and forming at least one butt-joining member; pressing impregnating briquette of easily melting material; then assembling members of article and placing onto assembly impregnating briquette; arranging protector between impregnating briquette and assembly of article members; sintering assembly and simultaneously infiltrating it with easily melting material.
EFFECT: improved accuracy of article geometry, enhanced strength of article members.
