Abstract
Método de fabricación y procesado de microhilos metálicos amorfos revestidos de cubierta aislante con elevadas propiedades magnéticas. El microhilo se prepara calentando la aleación del metal deseada mediante un horno de inducción de alta frecuencia contenida en el interior de un tubo de vidrio. El calor del metal ablanda el tubo de vidrio y la extracción del microhilo se realiza mediante el arrollamiento del capilar de vidrio rellenado de la aleación metálica en un bobina que gira convenientemente. El control del ritmo de enfriamiento permite la obtención de la microestructura metálica amorfa. El comportamiento magnético (alta susceptibilidad inicial, bajo campo coercitivo y bajo campo de anisotropía) se controlará eligiendo la composición nominal de la aleación, el tiempo de exposición a la temperatura de sobrecalentamiento, la relación entre el diámetro de núcleo metálico y el diámetro total, y la temperatura y las condiciones de tratamiento térmico posterior a la fabricaciónMethod of manufacturing and processing of amorphous metallic microwires coated with an insulating covering with high magnetic properties. The microwire is prepared by heating the desired metal alloy through a high-frequency induction furnace contained within a glass tube. The heat from the metal softens the glass tube and the removal of the microwire is done by winding the glass capillary filled with the metal alloy into a conveniently rotating coil. Control of the cooling rate allows obtaining the amorphous metallic microstructure. The magnetic behavior (high initial susceptibility, low coercive field and low anisotropy field) will be controlled choosing the nominal composition of the alloy, the time of exposure to the superheat temperature, the relationship between the diameter of the metal core and the total diameter, and post-manufacturing temperature and heat treatment conditions
