Title
(EN) METHOD FOR THE POWDER-METALLURGICAL PRODUCTION OF MAGNETIC CORES
(ES) MÉTODO PARA LA FABRICACIÓN PULVIMETALÚRGICA DE NÚCLEOS MAGNÉTICOS
(FR) PROCÉDÉ POUR LA FABRICATION DE NOYAUX MAGNÉTIQUES PAR MÉTALLURGIE DES POUDRES
Abstract
(EN) The invention relates to a method for the powder-metallurgical production of magnetic cores, characterised in that it comprises (i) a first step of amorphisation of a mixture of magnetically soft powders by mechanical grinding; and (ii) a second step of FAST (Field Assisted Sintering Techniques) electrical consolidation of the powder amorphised in the first step.
(ES) Método para la fabricación pulvimetalúrgica de núcleos magnéticos que se caracteriza porque comprende (i) una primera etapa de amorfización de una mezcla de polvos magnéticamente blandos mediante molienda mecánica; y (ii) una segunda etapa de consolidación eléctrica FAST (Field Assisted Sintering Techniques) del polvo amorfizado en la primera etapa.
(FR) Procédé pour la fabrication de noyaux magnétiques par métallurgie des poudres, caractérisé en ce qu'il comprend (i) une première étape d'amorphisation d'un mélange de poudres magnétiquement douces par broyage mécanique; et (ii) une seconde étape de consolidation électrique FAST (Field Assisted Sintering Techniques) de la poudre amorphisée à la première étape.
