Abstract

Appareil et procédé permettant le revêtement galvanique d'une partie d'une surface interne sensiblement cylindrique d'un composant, caractérisés par l'utilisation d'un jet annulaire de solution électrolytique dirigé sur la surface du composant à galvaniser. Par exemple, un gabarit (32) définit une zone galvanoplastique (50) dans laquelle le composant est adapté pour être monté avec l'axe de la surface galvanoplastique sensiblement verticale. Un bouchon (54) est adapté pour fermer l'extrémité de la surface, et est monté sur une tige (52) autour de laquelle est disposé un conduit tubulaire (60) qui se termine à une de ses extrémités, dans le voisinage axial du bout du composant. Le conduit forme, avec la tige, un ajutage annulaire (63) destiné à la solution électrolytique. La tige porte une anode (56). Une cathode (70) rend le composant électriquement cathodique par rapport à l'anode.
