Abstract

Procedimiento para la producción de componentes sinterizados magnéticos blandos, en el que a una mezcla de polvo se añade un aglutinante termoplástico así como se genera la forma de un cuerpo verde a través de prensado a continuación se sinteriza el cuerpo verde, caracterizado porque como materiales de partida para la mezcla de polvo se utiliza un polvo de Fe13 Cr, Fe17 Co o Fe48 Co2V o una mezcla de estos polvos, porque la mezcla de polvo contiene un porcentaje de polvo fino de 5 a 30 % en masa con respecto al material total de partida con un tamaño medio del grano de 5 a 40 µm, y porque la mezcla es prensada a una temperatura, que está por encima de la temperatura de reblandecimiento del aglutinante termoplástico, para formar el cuerpo verde.Procedure for the production of soft magnetic sintered components, in which a thermoplastic binder is added to a powder mixture as well as the shape of a green body is generated by pressing then the green body is sintered, characterized in that as materials of A powder of Fe13 Cr, Fe17 Co or Fe48 Co2V or a mixture of these powders is used for the powder mixture, because the powder mixture contains a fine powder percentage of 5 to 30% by mass with respect to the total material of starting with an average grain size of 5 to 40 µm, and because the mixture is pressed at a temperature, which is above the softening temperature of the thermoplastic binder, to form the green body.
