Abstract

La présente invention consiste à réaliser à partir d'une source d'étain 6 une atmosphère de vapeur d'étain qui contienne, en plus, un composé d'étain tres volatil à l'état gazeux, provenant du substrat 8, et à maintenir dans cette atmosphère les parties de la surface 2 à revêtir d'une couche de Nb3 sn, pendant un laps de temps prétabli, à une température comprise entre 900 et 1 500 degrés C, pour permettre la formation de la couche de Nb3 Sn. Les avantages de ce procédé consistent dans le fait qu'il permet de revêtir de couches de Nb3 Sn d'une grande uniformite et de haute qualité des surfaces de niobium d'une forme quelconque. Application : notamment à la fabrication de résonateurs supraconducteurs.
