Procedimiento para la fabricación según la metalurgia del polvo de un cuerpo de rotación, en el que a) se prensa un primer cuerpo de partida (1) de polvo metálico, b) se forma un segundo cuerpo de partida (5; 10) separado del primer cuerpo de partida (1) de metal, c) los cuerpos de partida (1, 5; 1, 10) se colocan adyacentes entre sí con superficies frontales (4, 6; 4, 11) con respecto a un eje longitudinal (L) del cuerpo de rotación en contacto axial, d) y a través de sinterización común se sinterizan fijamente entre sí de forma duradera, e) siendo prensado el primer cuerpo de partida (1) a partir de un polvo a base de aluminio y siendo formado el segundo cuerpo de partida (5; 10) a partir de un material de aluminio f) y los cuerpos de partida (1, 5; 1, 10) son sinterizados entre sí en las superficies frontales (4, 5; 4, 11), g) en el que uno de los cuerpos de partida (1, 5; 1, 10) es colocado para la sinterización común sobre el otro y durante la sinterización es presionado con su propio peso contra el otro de los cuerpos de partida (1, 5; 1, 10).
Powder-metallurgically producing a rotational body, comprises: (a) compacting a first starting body from metal powder; (b) forming a second starting body from metal, separately from the first starting body; (c) placing the starting bodies against each other in axial contact via end faces with respect to a longitudinal axis of the rotational body; and (d) permanently and firmly sintering the first starting body and the second starting body to each other by collective sintering.
