Description

Verfahren zur Veraluminierung von Gegenständen aus Eisen und Stahl Der Erfolg des Verfahrens des Hauptpatents 632993, betreffend die Veraluminierung von Gegenständen aus Eisen -und Stahl, besteht darin, daß durch Ausschluß der Luft während der gesamten der Veraluminierung dienenden Maßnahmen, d. h. vom Einbringen der zu veraluminierenden Artikel in den Ofen bis zum Austritt der abgekühlten Gegenstände aus demselben, ein völlig dichter, geschxneidiger, d. h. biegsamer, nicht abblätternder und trotzdem dünner Aluminiumüberzug erzielt wird. Derselbe eignet sich infolge seiner Dichte auch zur Erzeugung von isolierenden und korrosionsbeständigen Oxydschichten, was .bei den bisherigen Veraluminierungsverfahren nicht möglich war. -Die Erfindung betrifft eine weitere Ausgestaltung des Verfahrens und ist dadurch gekennzeichnet, daß anstatt des Aluminiumschmelzbades zur Herstellung des Überzuges Alunjiniumlegerungen, insbesondere Aluminium-Zink-Legjerungen, verwendet werden.Process for the aluminizing of objects made of iron and steel The success of the process of the main patent 632993, concerning the aluminizing of objects made of iron and steel, consists in the fact that by excluding the air during the entire process of aluminizing, ie introducing the to be aluminized Articles in the oven until the cooled objects emerge from the same, a completely dense, flexible, ie flexible, non-flaking and nevertheless thin aluminum coating is achieved. Due to its density, it is also suitable for the production of insulating and corrosion-resistant oxide layers, which was not possible with the previous aluminizing processes. The invention relates to a further embodiment of the method and is characterized in that, instead of the molten aluminum bath, aluminum layers, in particular aluminum-zinc layers, are used to produce the coating.

Es hat sich herausgestellt, daß die Verwendung solcher Legierungen nicht nur die Geschmeidigkeit des Aluminiumüberzuges, sondern auch seine Dichte in überraschend günstigem Maße erhöht. Der Zusatz des Zinks zu der anzuwendenden Aluminium-Zink-Legierung bewegt sich in den für Aluminium-Zink-Legierungen normalen und üblichen Grenzen. Ein Optimum ist innerhalb eines Zusatzes von r bis ro % vorhanden.It has been found that the use of such alloys not only the suppleness of the aluminum coating, but also its density increased to a surprisingly favorable extent. The addition of zinc to the one to be applied Aluminum-zinc alloy is in the normal range for aluminum-zinc alloys and usual limits. An optimum is present within an addition of r to ro%.

Es hat sich des weiteren herausgestellt, daß die Verwendung von Aluminiumlegierungen zum Zwecke der Herstellung von Aluminiumüberzügen auf Eisen und Stahl, abgesehen von dem Verfahren des Hauptpatents, auch bei anderen Aluminierungsverfahren eine überraschende Verbesserung des Aluminiumüberzuges bedeutet.It has also been found that the use of aluminum alloys for the purpose of producing aluminum coatings on iron and steel from the process of the main patent, also one in other aluminizing processes means a surprising improvement in the aluminum coating.

Es braucht nicht besonders darauf hingewiesen zu werden, daß bei ,Anwendung von Aluminiumlegierungen für die Durchführung der Verah""inierung auch die besonderen Bedingungen des Schmelzbades, insbesondere der Temperatur, im Hinblick auf die Zusammensetzung der Legierung entsprechender Änderungen bedürfen.Needless to say, when, application of aluminum alloys for the implementation of the processing also the special Conditions of the molten bath, in particular the temperature, with regard to the composition the alloy require corresponding changes.

Es ist bekannt, auf Eisenteile auf schmelzflüssigem Wege Aluminiumlegierungen. aufzubringen. Die Erfindung besteht demgegenüber darin, daß das Verfahren des Hauptpatents zur Aufbringung der Legierung verwendet wird.It is known to use molten aluminum alloys on iron parts. to raise. The invention consists in the fact that the method of the main patent is used to apply the alloy.
