Description
Procédé<B>de</B> réalisation d'une soudure étanche entre une pièce de verre et une<B>pièce</B> creuse en métal et soudure obtenue suivant ce procédé. La présente invention se rapporte<B>à</B> un procédé de réalisation d'une soudure étanche entre une pièce de verre et une pièce creuse en métal et<B>à</B> une soudure obtenue suivant ce procédé.
Le dessin ci-annexé, donné<B>à</B> titre d'exem ple, se rapporte<B>à</B> deux joints obtenus par le procédé suivant l'invention.
Dans les deux figures,<B>1</B> représente le, tube de verre et 2 le tube métallique entre lesquels un joint étanche et robuste doit être assuré<B>; 3</B> représente l'extrémité du tube mé tallique dont la paroi est amincie et pourvue à l'intérieur d'un revêtement d'émail 4. Ce revêtement s'obtiendra, par exemple, de la façon connue en appliquant sur la paroi d'abord un mordant ou contre-oxyde, puis une couche d'émail proprement dit;
le mor dant pourra avoir la composition suivante Si 02 45 % Pb <B>0 .</B> 28 % <B>-</B> Na,, <B>0</B> -. 20 % <B>p</B> B2 03 <B>6</B> % Sb2 0-3 <B>:
1</B> % et l'émail la composition suivante<B>:</B> Si 02<B>100 ;</B> C03 K2 <B>80;</B> cendres d'os<B>:</B> 200. Une -bague de verre fusible<B>5</B> est inter posée entre le tube de verre<B>1</B> et le tube métallique<B>3</B> et ëst écrasée entre ces deux pièces grâce<B>à</B> une pression sur celle-ci obte nue par rapprochement de ces deux pièces l'une vers l'autre, étant entendu que durant cette phase on chauffe, par exemple au cha lumeau, l'extrémité<B>3</B> du tube métallique.
La bague<B>5</B> peut indifféremment être fixée soit au tube<B>1,</B> soit au tube<B>3,</B> avant le rappro chement des pièces bien qu'on puisse trouver plus commode de la fixer au tube<B>1</B> dans le joint représenté fig. <B>1</B> et au tube 2 dans le joint de la fig. 2<B>;</B> dans tous les cas, la bague sera de préférence située<B>à</B> une certaine dis tance de l'extrémité<B>du</B> tÙb & e de verre<B>1.</B>
Dans le joint de la fig. 2, le tube 2 au lieu d'être évasé<B>à</B> son extréinité <B>Si</B> comme représenté<B>à</B> la fig. <B>1,</B> conserve sa forme, tandis que le tube de verre<B>1</B> est rétréci<B>à</B> son extrémité, comme il est représenté en vue de permettre son introduction dans le tube 2. <B>Il</B> convient de noter que la bague de verre fusible contribue également<B>à</B> former surépais- seur et<B>à</B> augmenter ainsi la résistance (lu tube de verre<B>à</B> la compression du tube mé tallique.
Il va de soi, qu'il faut choisir le mordant pour qu'il s'applique bien au métal utilisé et (lue l'émail employé doit convenir audit mor- daut et au verre fusible, lequel verre fusible doit être choisi en égard au tube de verre employé.
Les joints en que9tion s'emploieront avec avantage dans les tubes<B>à</B> vide<B>à</B> grande puissance utilisés en radio-technique.
Process <B> of </B> realization of a tight weld between a piece of glass and a <B> part </B> of metal and weld obtained according to this process. The present invention relates <B> to </B> a method of producing a sealed weld between a piece of glass and a hollow metal piece and <B> to </B> a weld obtained by this method.
The appended drawing, given <B> by </B> by way of example, relates <B> to </B> two joints obtained by the process according to the invention.
In both figures, <B> 1 </B> represents the glass tube and 2 the metal tube between which a tight and robust seal must be ensured <B>; 3 </B> represents the end of the metallic tube, the wall of which is thinned and provided inside with an enamel coating 4. This coating will be obtained, for example, in the known manner by applying to the wall first a mordant or counter-oxide, then a layer of enamel proper;
the mor dant may have the following composition Si 02 45% Pb <B> 0. </B> 28% <B> - </B> Na ,, <B> 0 </B> -. 20% <B> p </B> B2 03 <B> 6 </B>% Sb2 0-3 <B>:
1 </B>% and the enamel the following composition <B>: </B> Si 02 <B> 100; </B> C03 K2 <B> 80; </B> bone ash <B> : </B> 200. A fusible glass-ring <B> 5 </B> is interposed between the glass tube <B> 1 </B> and the metal tube <B> 3 </B> and is crushed between these two parts thanks <B> to </B> a pressure on it obtained by bringing these two parts towards each other, it being understood that during this phase one heats, for example with the heating lumeau, the <B> 3 </B> end of the metal tube.
The ring <B> 5 </B> can indifferently be fixed either to the tube <B> 1, </B> or to the tube <B> 3, </B> before the approximation of the parts although one can find more convenient to fix it to the tube <B> 1 </B> in the joint shown in fig. <B> 1 </B> and to tube 2 in the joint in fig. 2 <B>; </B> in all cases, the ring should preferably be located <B> at </B> a certain distance from the end <B> of the </B> glass tube < B> 1. </B>
In the seal of fig. 2, the tube 2 instead of being flared <B> at </B> its extremity <B> Si </B> as shown <B> at </B> in fig. <B> 1, </B> retains its shape, while the glass tube <B> 1 </B> is narrowed <B> at </B> its end as shown in order to allow its insertion in tube 2. <B> It </B> should be noted that the fusible glass ring also contributes <B> to </B> forming excess thickness and thus <B> to </B> increase the resistance ( read glass tube <B> to </B> the compression of the metal tube.
It goes without saying that the mordant must be chosen so that it applies well to the metal used and (considering the enamel used must be suitable for said bite and for the fusible glass, which fusible glass must be chosen with regard to the glass tube used.
The joints in que9tion will be used with advantage in the tubes <B> to </B> vacuum <B> to </B> high power used in radio-technique.
