Abstract

Un método de fabricación de cuerpos densificados magnéticos para usar en aparatos de corriente continua, que incluye la etapa de comprimir microlaminaciones, obtenidas de un material laminar ferromagnético y que posee un contenido de carbono bajo, para formar un cuerpo densificado de configuración previamente determinada, caracterizado porque dichas microlaminaciones son partículas sin revestir de forma alargada, y la etapa de compresión va seguida de recocido del cuerpo densificado en una atmósfera no oxidante.
