Abstract

L'invention concerne la fabrication des cathodes et, plus particulièrement, une simplification permettant d'en réduire le coût. Une seule et même pièce 1 en alliage de nickel constitue à la fois le manchon et le support du revêtement 3 émetteur d'électrons qui sont habituellement deux pièces distinctes Le support 4 de la pièce 1 est associé à un isolant 5 dans lequel sont noyées les broches 6 d'alimentation du filament 2. L'alliage de nickel comporte au moins 10 % en poids d'un ou plusieurs éléments tels que l'iridium, le molybdène, le tantale, etc L'invention trouve une application, notamment dans les tubes pour récepteurs de télévision en couleurs.
