Abstract

The miniaturization of the brazed joint construction of a thin non-metal disk with a hollow thin-walled metal cylinder for operation as part of a vacuum device in a wide temperature range was carried out. The main feature of this development was the creation of a brazed joint construction, in which the enclosing shell on non-metal disk, in this case of leucosapphire, was made from titanium foil 100 µm thick. Regimes of brazing were installed and the brazed windows were made. Vacuum density tests were carried out. The high efficiency of this joint construction was shown after various regimes of thermal cycling of brazed samples.
