Abstract

PARA LA ELABORACION DE UN PRODUCTO DE MATERIAL DE CONTACTO BASADO EN PLATA SE HA PREVISTO PRIMERO LA FORMACION DE UNA MEZCLA DE POLVO DE PLATA Y HIERRO, EN DONDE EL HIERRO ES UTILIZADO EN FORMA DE UN POLVO TENIENDO UN TAMAÑO DE GRANO MEDIO DE MAS DE 1 MI M. ESTA MEZCLA ES ENTONCES PROCESADA ADICIONALMENTE EN UNA MANERA METALURGICA DE POLVO PARA FORMA EL PRODUCTO, OXIDANDOSE EL HIERRO PARA FORMAR OXIDO DE HIERRO. EL PROCEDIMIENTO PRODUCE UN MATERIAL DE CONTACTO DE OXIDO DE HIERRO Y DE PLATA CUYAS PARTICULAS DE OXIDO DE HIERRO TIENEN UNA TAMAÑO DE GRANO MEDIO MAYOR QUE EL CORRESPONDIENTE A LOS MATERIALES DE CONTACTO CONOCIDOS HASTA AHORA. UN MATERIAL DE CONTACTO DE ESTE TIPO MUESTRA ALTA DUCTILIDAD AUNQUE SUS BUENAS PROPIEDADES DE CONEXION PERMANECEN INMUTABLES. ES ADECUADO EN PARTICULAR PARA UTILIZACION COMO UNA PARTE DE CONTACTO EN FORMA DE UN REMACHE DE UN DISPOSITIVO DE CONEXION DE INGENIERIA DE POTENCIA.
