Description

  

  Verfahren zur Herstellung von Gegenständen, bei denen ein Metall und Glas durch  Aneinander     sehmelzen    in Verbindung gebracht sind.    Die Erfindung bezieht sich auf ein Ver  fahren zur Herstellung von Gegenständen,  bei denen ein Metall und Glas durch     Anein-          anderscllmelzen    in Verbindung gebracht  sind, nach welchem insbesondere luftdichte  Verbindungen erzielt werden können. Die       Anmelderin    hat schon früher gefunden, dass  die     Verwendung    von Chromeisen als Material  zum     Anschmelzen    an Glas andern Stoffen  gegenüber grosse Vorteile bietet.

   Es wurde  aber bemerkt, dass unter bestimmten Um  ständen das für das     Anschmelzen    an Glas  in Betracht kommende Chromeisen dermassen       oxydieren    kann, dass einige der günstigen  Eigenschaften verloren gehen können.  



       ich    dem Verfahren gemäss der     vor-          2        N#     liegenden Erfindung wird dieser Nachteil       beseitigt,    indem man zur Anfertigung der  Metallteile,. welche mit dem Glas in Verbin  dung gebracht werden, eine aus Eisen, Chrom  und Aluminium bestehende, rostsichere Le  gierung verwendet. Vorteilhaft wird eine     Le-          Oierung    verwendet mit einem Aluminium-    weise weniger als 5 %. Sogar mit weniger  als 1 % Aluminium enthaltenden Legierun  gen hat man sehr     gute    Ergebnisse erzielt.

    Als Beispiel einer für das     Anschmelzen    an  Glas geeigneten Legierung sei     eine    aus 25  Chrom, 1/2 % Aluminium und im übrigen  aus Eisen bestehende Legierung erwähnt.  Die Zusammensetzung der Legierung richtet  sich nach der Glasart, mit der sie in Ver  bindung     gebracht    werden soll. Im allgemei  nen ist es vorteilhaft, bei niedrigen Chrom  gehalten den Aluminiumgehalt zu     ver-          gröffern.     



  Gemäss dem Verfahren der vorliegenden  Erfindung können zum Beispiel elektrische  Entladungsröhren, Lampen oder dergleichen,  bei denen Elektroden oder andere Metall  teile mit Glas in Verbindung gebracht sind,  hergestellt werden.



  Process for the manufacture of articles in which a metal and glass are connected by melting together. The invention relates to a method for the production of objects in which a metal and glass are connected by melting one another, according to which, in particular, airtight connections can be achieved. The applicant has already found earlier that the use of chrome iron as a material for melting on glass offers great advantages over other materials.

   It was noted, however, that under certain circumstances the chromium iron used for melting on glass can oxidize to such an extent that some of its favorable properties can be lost.



       I the method according to the present invention, this disadvantage is eliminated by making the metal parts. which are brought into contact with the glass, a rustproof alloy made of iron, chrome and aluminum is used. It is advantageous to use a leverage with an aluminum content of less than 5%. Very good results have even been achieved with alloys containing less than 1% aluminum.

    As an example of an alloy suitable for melting on glass, an alloy consisting of 25 chromium, 1/2% aluminum and the rest of iron may be mentioned. The composition of the alloy depends on the type of glass with which it is to be brought into connection. In general, it is advantageous to keep the aluminum content low while keeping the chromium low.



  According to the method of the present invention, for example, electrical discharge tubes, lamps or the like, in which electrodes or other metal parts are brought into contact with glass, can be produced.
