Zusammenfassung:FIELD: metallurgy. SUBSTANCE: method involves molding bilayer blank with easily melting surface layer, subsequent sintering of it combined with impregnation of material of basic layer by easily melting material of surface layer, performing molding of bilayer blank by gas thermal deposition onto cylindrical surface of substrate pressed at pressure 500-700 MPa of coating whose mass consisting 12-18% of substrate mass. EFFECT: enhanced quality of powder blank products.
