Description

Zierfahren zum Überziehen von Gegenständen aus Glas oder Keramik mit einem lötbaren Metallüberzug Zum Überziehen von Gegenständen aus Glas oder Porzellan mit einem lötbaren Metallüberzug ist es bekannt, Kupferazetylazetonat zu verwenden. Die damit hergestellten Kupferüberzüge haben jedoch. den Nachteil, daß sie sich infolge der verhältnismäßig niedrigen Schmelztemperatur und der leichten Legierbarkeit des Kupfers mit Hartloten nicht löten lassen, ohne daß sich der Kupferüberzug abhebt oder auflöst.Zierfahren for covering objects made of glass or ceramic with a solderable metal cover for covering objects made of glass or porcelain with a solderable metal coating it is known to use copper acetylacetonate. However, the copper coatings produced with it have. the disadvantage that they are due to the relatively low melting temperature and easy alloyability Do not solder the copper with brazing solder without the copper coating lifting off or dissolves.

Diese Nachteile werden erfindungsgemäß dadurch vermieden, daß Eisen-, Nickel- bzw. Kobaltazetylazetonate bei erhöhter Temperatur auf den zu überziehenden. Gegenständen zum Zerfallen gebracht werden. Die damit hergestellten Überzüge haben eine höhere Schmelztemperatur und weisen eine schwerere Legierbarkeit mit silberhaltigen oder kupferhaltigen Loten auf, so daß mit ihnen Hartlotverbindungen leicht hergestellt werden können. Gemäß der weiteren Erfindung können auch Metallüberzüge aus Legierungen, z. B. Eisen-Nickel-Legierungen, hergestellt werden, indem man: die zu überziehenden Körper in einem entsprechend gemischten Dampf von. Azetylazetonaten erhitzt. Diese Überzüge aus Legierungen haben den weiteren Vorteil, daß sie rostfrei sind.These disadvantages are avoided according to the invention in that iron, Nickel or cobalt acetylazetonate at elevated temperature on the to be coated. Objects are brought to disintegrate. The coatings made with it have have a higher melting temperature and are more difficult to alloy with silver-containing or copper-containing solders, so that hard-soldered connections are easily made with them can be. According to the further invention, metal coatings made of alloys, z. B. iron-nickel alloys, can be prepared by: the to be plated Body in a suitably mixed vapor of. Acetylazetonaten heated. These Alloy coatings have the further advantage that they are rustproof.

Die Azetylazetonate haben gegenüber den für diese Zwecke auch verwendeten Carbonylen. Vorteile. Die Carbanyle haben nämlich dem Nachteil, daß sie wegen ihrer Giftigkeit und des als Verdünnungsmittel benutzten, bekanntlich farb- und geruchlosen Kohleno,xyds gefährlich sind. Es sind deswegen auch besondere Schutzmaßnahmen notwendig. Die Azetylazetonate sind dagegen relativ ungefährlich und haben den weiteren Vorteil, da,ß zu ihrer Verdünnung ungefährliche Gase, wie Kohlensäure, Stickstoff oder andere inerte Gase, verwendet werden können. Das Verfahren wird in der Wärme durchgeführt bei verhältnismäßig niedrigen Temperaturen, und zwar bei etwa 400° C.The Acetylazetonate have compared to those used for these purposes as well Carbonyls. Advantages. The carbanyls have the disadvantage that they because of their Toxicity and the known colorless and odorless used as a diluent Coalso, xyds are dangerous. Therefore, special protective measures are necessary. The acetylazetonates, on the other hand, are relatively harmless and have the further advantage of da, ß harmless gases such as carbon dioxide, nitrogen or others to dilute them inert gases, can be used. The procedure is carried out in the heat at relatively low temperatures, namely at around 400 ° C.

Die metallüberzogenen. Gegenstände sind für alle Zwecke brauchbar, bei welchen ein Glas- oder Keramikkörper ganz oder teilweise eine Metallschicht haben muß. Das kann an solchen Stellen sein, an welchen der Körper durch Löten oder Schweißen mit anderen Metallteilen verbunden werden soll. Hierfür kommen Porzellanrohre für Gleichrichter, Durchführungen für Kondensatoren, Hochohmwiderstände, statische Abschirmungen an Hochspannungsisolatoren, Porzellandurchführungen für schlagwettergeschützte elektrische Geräte usw. in Betracht.The metal-coated ones. Objects are useful for all purposes, in which a glass or ceramic body wholly or partially has a metal layer must have. This can be in those places where the body has been soldered or Welding is to be connected to other metal parts. Porcelain tubes are used for this for rectifiers, bushings for capacitors, high resistance, static Shields on high-voltage insulators, porcelain bushings for firedamp-proof electrical devices etc. into consideration.

Es sind zwar Azetylazetonate zur Herstellung von Metallüberzügen schon verwendet worden., doch wurden diese nicht zur Herstellung von Überzügen auf Gegenständen aus Glas und Keramik benutzt, um diese mit einer lötbaren Metallschicht zu versehen. Auch ist die Verwendung von speziell von Eisen-, Nickel- bzw. Kobaltazetylazetonaten für diesen neuen Zweck nicht vorgeschlagen.Acetylazetonates are used to produce metal coatings been used., but these were not used for the production of coatings on objects made of glass and ceramic used to provide them with a solderable metal layer. The use of especially iron, nickel or cobalt acetylacetonates is also possible not suggested for this new purpose.
