Description
Verfahren zur besseren Haftbarmachung von aufgestäubten rdetallüberzügen auf anderen Netallen. Nach der Patentschrift318462 wird zur besseren Haftbarmachung von nach dein Spritzverfahren aufgebrachten Metallüberzügen auf andern Metallen in der Weise verfahren, daß die überzogenen Gegenstände stufenweise auf solche Temperaturen erwärmt werden, daß eine Verschweißung oder Legierung zwischen dem Überzugsmetall und Grundmetall stattfindet. Die stufenweise Erwärmung braucht nun nicht notwendigerweise eine aufsteigende zu sein, sondern sie kann auch nach vorliegender weiterer Ausbildung des vorerwähnten bekannten Verfahrens in absteigendem Sinne erfolgen. Auf diese Weise gelingt es, z. D. sehr dauerhafte Verschweißungen von nach dem Tauchverfahren erzeugten schmelzflüssigen Verzinkungen mit nach dem Spritzverfahren hergestellten Zinnüberzügen zu Wege zu bringen.Process for better adhesion of dusted metal coatings on other networks. According to the patent specification 318462 is for better adhesion of metal coatings applied by spraying on other metals proceed in such a way that the coated articles are gradually brought to such temperatures be heated that a weld or alloy between the clad metal and base metal takes place. The gradual warming is not necessary now an ascending one, but it can also be done after further training of the aforementioned known method in the descending sense. To this Way it succeeds z. D. very permanent welds after the immersion process produced molten zinc coatings with those produced by the spraying process To bring tin coatings to the way.
Das Verfahren eignet sich ganz besonders gut zur Metallisierung von Hohlgefäßen, wie z. B. eisernen Milchtransportkannen, indem es ermöglicht, die Gefäße innenseitig mit einem organischen Säuren leicht wiederstehenden Zinnüberzug auszustatten, der durch Verschweißung mit dem vorher im schmelzflüssigen Tauchbade hergestellten Zinküberzug verbunden ist. Der Zinküberzug seinerseits ist viel beständiger gegen die von außen her auf den Gegenstand ausgeübten echanischen und chemischen Beanspruchungen (Rostbildung) und daher für die Lebensdauer zahlreicher Gegenstände des täglichen Gebrauches viel wirkungsvoller, als eine nur auf dem feuerflüssigen oder auf dem Spritzwege hergestellte Verzinnung gleichartiger Gegenstände.The process is particularly suitable for metallizing Hollow vessels, such as B. iron milk transport cans by allowing the vessels to be provided on the inside with a tin coating that is easily resistant to organic acids, the one produced by welding with the one previously produced in the molten immersion bath Zinc coating is connected. The zinc coating, in turn, is much more resistant to the mechanical and chemical stresses exerted on the object from the outside (Rust formation) and therefore for the service life of numerous everyday objects Use much more effectively than one only on the fiery or on that Tinning of similar objects produced by spraying paths.
Die Temperatur der bei schmelzflüssigen Verzinkungen angewandten Schmelzbäder wird durchweg auf 46o bis 48o' belassen. Eine gleich hohe Temperatur nimmt daher auch der in das Schmelzbad eingetauchte zu verzinkende Gegenstand an. Ist nun das Arbeitsstück, z. B. eine Milchtransportkanne, durch Eintauchen in das Schmelzbad verzinkt worden, so wird es im Anschluß an diese erste Stufe der Bearbeitung mittels der Spritzpistole innenseitig bespritzt, wobei die Temperatur infolge der Expansionskälte des Zerstäubungsmittels sehr schnell von 480Q auf 43o' heruntersinkt. Da der Spritzvorgatig sich sehr schnell abspielt, so bleibt der Zinküberzug während der Dauer des Spritzvorganges noch plastisch genug, um sich mit den auftreffenden Zinnteilchen begierig zu verschweißen. Auf diese Weise wird also ein sehr dauerhafter Zinn-Zinküberzug hergestellt.The temperature of the weld pools used in molten zinc plating is left at 46o to 48o 'throughout. An equally high temperature therefore takes also the object to be galvanized immersed in the weld pool. Now is that Work piece, e.g. B. a milk jug, by immersing it in the molten bath has been galvanized, so it is after this first stage of processing by means of the spray gun is sprayed on the inside, the temperature being due to the expansion cold of the atomizing agent drops very quickly from 480Q to 43o '. Since the injection happens very quickly, the zinc coating remains for the duration of the spraying process still plastic enough to be eagerly welded to the hitting tin particles. In this way, a very permanent tin-zinc coating is produced.
