Abstract

L'INVENTION CONCERNE UNE PROCEDE DE PULVERISATION DE PLATINE SUR UN CORPS D'ELECTROLYTE SOLIDE POUR ELECTRODE DE CAPTEUR D'OXYGENE DANS DES GAZ D'ECHAPPEMENT. L'ELECTRODE EST PULVERISEE DANS UNE ATMOSPHERE CONTENANT ESSENTIELLEMENT PLUS DE 50 D'OXYGENE ETOU D'AZOTE EN VOLUME. DES CAPTEURS AVEC DES TEMPS DE TRANSITION FAIBLES ET SYMETRIQUES SONT AINSI PRODUITS. L'INVENTION S'APPLIQUE NOTAMMENT AUX CAPTEURS D'OXYGENE DANS DES GAZ D'ECHAPPEMENT POUR VEHICULES AUTOMOBILES.THE INVENTION RELATES TO A PROCESS FOR SPRAYING A PLATINUM ON A BODY OF SOLID ELECTROLYTE FOR OXYGEN SENSOR ELECTRODE IN EXHAUST GASES. THE ELECTRODE IS SPRAYED INTO AN ATMOSPHERE CONTAINING ESSENTIALLY MORE THAN 50 OXYGEN AND OR NITROGEN BY VOLUME. SENSORS WITH LOW AND SYMMETRICAL TRANSITION TIMES ARE THUS PRODUCED. THE INVENTION APPLIES IN PARTICULAR TO OXYGEN SENSORS IN EXHAUST GASES FOR MOTOR VEHICLES.
