Abstract

L'invention a pour objet un procédé de fabrication d'une grille pour tube électronique, du type hexagonal en <<nids d'abeille >>. Il consiste à : - utiliser un ensemble de feuilles 1, 2, 3 de métal réfractaire, sur chacune desquelles on dépose des bandes 4 parallèles (pas p) d'un métal ayant une basse température de fusion; - empiler les feuilles en les décalant de p/2 les unes par rapport aux autres, puis les braser; - réaliser l'expansion de la structure puis la finition de la grille. La grille obtenue par ce procédé est notamment utilisable comme grille de commande d'un canon à électrons.
