Abstract

Procédé de traitement et de dégazage de tubes cathodiques ayant été précédemment dégazés par évaporation et condensation d'une matière à base de baryum. Le procédé consiste à transformer la pellicule de baryum ainsi formée en carbonate de baryum par contact avec cette pellicule d'un mélange gazeux comprenant essentiellement du CO2 et de la vapeur d'eau. Le vide est ensuite créé dans le tube avant que ce dernier soit de nouveau dégazé par évaporation et condensation rapide d'un getter contenant du baryum. Domaine d'application : traitement de reprise de tubes cathodiques.
