Abstract

PROCEDIMIENTO PARA LA OBTENCION DE MATERIALES COMPUESTOS, DE CONTACTO ELECTRICO, A BASE DE COBRE. CONSISTE EN SOMETER A FUSION COBRE JUNTO CON AL MENOS 0,01-7% DE ANTIMONIO Y/O 0,5-20% DE GALIO Y/O 0,5-10% DE GERMANIO, BAJO ATMOSFERA PROTECTORA; SEGUIDO DE TRATAMIENTO TERMICO MEDIANTE RECOCIDO A UNA TEMPERATURA ENTRE 600 C Y 950 C; PULVERIZADO DE LA ALEACION FORMADA; COMBINACION CON UN COMPONENTE ACTIVO INSOLUBLE EN LA ALEACION, TAL COMO OXIDO METALICO, METAL DE PUNTO DE FUSION ELEVADO, CARBONO O CARBURO; Y PRENSADO O PRENSADOEXTRUSION. ESTOS MATERIALES TIENEN APLICACIONES PARA FABRICACION DE DISPOSITIVOS DE CONMUTACION DE BAJA TENSION O DE CONMUTACION DE INSTALACIONES.PROCEDURE FOR OBTAINING COMPOUND MATERIALS, OF ELECTRICAL CONTACT, BASED ON COPPER. IT CONSISTS OF SUBMITTING COPPER FUSION TOGETHER WITH AT LEAST 0.01-7% ANTIMONY AND / OR 0.5-20% GALIUM AND / OR 0.5-10% GERMANIUM, UNDER PROTECTIVE ATMOSPHERE; FOLLOWED THERMAL TREATMENT THROUGH ANNEALING AT A TEMPERATURE BETWEEN 600 C AND 950 C; SPRAYING OF FORMED ALLOY; COMBINATION WITH AN INSOLUBLE ACTIVE COMPONENT IN THE ALLOY, SUCH AS METALLIC OXIDE, HIGH MELTING POINT METAL, CARBON OR CARBIDE; AND PRESSING OR PRESSING EXTRUSION. THESE MATERIALS HAVE APPLICATIONS FOR THE MANUFACTURE OF LOW VOLTAGE SWITCHING DEVICES OR OF SWITCHING FACILITIES.
