Description

Strahlenaustrittsfenster für Kathoden- oder Röntgenstrahlenröhren Bekannt sind Folien aus Kupfer und Aluminium sowie auf galvanoplastischem Wege hergestellte Nickelfolien in ihrer Anwendung als Strahlenaustrittsfenster für Kathodenstrahlenröhren.Radiation exit window for cathode or X-ray tubes Foils made of copper and aluminum and produced by electrodeposition methods are known Nickel foils in their application as radiation exit windows for cathode ray tubes.

Diese bekannten Austrittsfenster haben den Nachteil, daß sie verhältnismäßig leicht bei chemischen Reaktionen angegriffen werden.These known exit windows have the disadvantage that they are relatively easily attacked in chemical reactions.

Erfindungsgemäß werden Strahlenaustrittsfenster für Kathoden- oder Röntgenstrahlenröhren unter Vermeidung der Nachteile der bisherigen Fenster an ihrer Außenseite mit einer gegen chemische Einwirkungen schützenden Schicht, z. B. aus Gold oder Platin oder deren Legierungen, bedeckt.According to the invention, radiation exit windows for cathode or X-ray tubes avoiding the disadvantages of the previous window at their Outside with a layer protecting against chemical effects, e.g. B. off Gold or platinum or their alloys.
