Zusammenfassung:	A sintered iron-based friction material consists of a sintered mixt. of (by wt.) 1-5 (pref. 2)% Cu, 3-6 (pref. 4)% NiSO4, 4-8 (pref. 4)% graphite, 1-3 (pref. 1)% pyroceramic, 3-10 (pref. 7)% CaSi2, 0.4-2 (pref. 1.5)% Si, 0.2-1 (pref. 0.5)% SiC, 0.2-2 (pref.1)% FeSi2, 0.5-5 (pref. 3)% asbestos and balance (pref. 76%) Fe. The material is useful in friction devices used in cars, tractors, aircraft, road-building machines and other devices operating under dry friction and liquid lubrication conditions. Compared with prior art sintered iron-based materials, the material has 1.5-3 times higher wear resistance and 1.2-1.4 times higher friction coefft. under liquid lubrication conditions, 1.4-1.7 times higher wear resistance and 1.2-1.3 times higher friction coefft. under dry friction conditions, and has 1.3 times higher ultimate strength and 1.2 times higher impact strength. In braking tests, the material showed a wear after 100 brakings of 4-8 microns with lubrication and 15-18 microns without lubrication, a friction coefft. of 0.13-0.14 with lubrication and 0.38-0.40 without lubrication, an ultimate strength of 12.3.13 kg/sq.mm and an impact strength of 0.7 kg.-m/sq.cm. L'INVENTION CONCERNE LA METALLURGIE DES POUDRES.LA MATIERE FRICTIONNELLE AGGLOMEREE A BASE DE FER, OBJET DE L'INVENTION, EST DU TYPE CONTENANT DU CUIVRE, DU SULFATE DE NICKEL, DU GRAPHITE ET DU "SITALL", ET EST CARACTERISEE EN CE QU'ELLE CONTIENT EN OUTRE DE L'AMIANTE, DU DISILICIURE DE CALCIUM, DU SILICIUM, DU CARBURE DE SILICIUM ET DU DISILICIURE DE FER. LA MATIERE EN QUESTION A LA COMPOSITION SUIVANTE ( EN MASSE): CUIVRE 1 A 5; SULFATE DE NICKEL 3 A 6; GRAPHITE 4 A 8; "SITALL" 1 A 3; DISILICIURE DE CALCIUM 3 A 10; SILICIUM 0,4 A 2; CARBURE DE SILICIUM 0,2 A 1; DISILICIURE DE FER 0,2 A 2; AMIANTE 0,5 A 5; FER LE SOLDE.L'INVENTION S'APPLIQUE NOTAMMENT AUX MATIERES FRICTIONNELLES POUR LA FABRICATION DES ENSEMBLES A FRICTION EMPLOYES SUR LES VEHICULES AUTOMOBILES, LES TRACTEURS, LES AVIONS ET LES ENGINS DE TRAVAUX PUBLICS.
