FIELD: powder metallurgy; production of part components; manufacture of structural and wear-resistant parts for mechanical engineering, instrumentation engineering, mining, processing and other industries.
SUBSTANCE: proposed method of connecting large parts made from powder includes preparation of iron-based burden and molding of parts, after which assembly is performed; partition which is impermeable for copper-based melt is laid between surfaces being connected. Then, layer of dross made on base of iron powder prepared from bidispersive powders is applied on surfaces of parts being connected. Copper-based impregnating briquettes are placed at the top and at the bottom of assembly and sintering is performed at simultaneous infiltration.
EFFECT: enhanced strength of connection and enhanced stability of properties.
