Abstract

CETTE INVENTION CONCERNE UN MATERIAU DE CONTACT UTILISABLE DANS LES DISPOSITIFS ELECTRIQUES PERMETTANT D'OUVRIR OU DE FERMER UN CIRCUIT AINSI QU'UN PROCEDE DE FABRICATION DE CE PRODUIT. CE MATERIAU EST CARACTERISE PAR L'ASSOCIATION A DE L'ARGENT DE CRISTAUX MIXTES DE CARBURE DE TUNGSTENE ET DE CARBURE DE TITANE DANS LA PROPORTION PONDERALE DE 20 A 40 PAR RAPPORT A LA MASSE TOTALE DU MATERIAU. LE PROCEDE CONSISTE A MELANGER LES PRODUITS A L'ETAT PULVERULENT, A LES COMPRIMER ET A LES FRITTER A UNE TEMPERATURE SUPERIEURE A 1050C. CE MATERIAU TROUVE SON APPLICATION EN PARTICULIER DANS LES CONTACTEURS ET DISJONCTEURS EQUIPANT LES LOCAUX D'HABITATION, LES APPAREILS MENAGERS ET LES INSTALLATIONS INDUSTRIELLES.
