Description

Verfahren zur Herstellung rostsicherer, hitzebeständiger ÜberzÜge aus Alunliniumbrolize auf Eisengegenständen. Das Hauptpatent bezieht sich auf 'ein Verfahren zur Herstellung rostsicherer, hitzebeständiger Überzüge aus Aluminiumbronze auf Eisengegenständen. Sein wesentlich neues Merkmal besteht darin, daß die Gegenstände zuvor geraubt, dann mit Zinkbronze hauchdünn angerieben oder schwach scherardisiert werden, worauf eine Aluminiumlackbronzeschicht aufgebracht und der Lack durch Erhitzen auf etwa 5oo' C ausgebrannt wird, wobei die Aluminiumschicht mit der Zink- und Eisenunterlage legiert wird.Process for the production of rustproof, heat-resistant coatings from Alunliniumbrolize on iron objects. The main patent relates to a method for producing rustproof, heat-resistant coatings of aluminum bronze on iron objects. Its essentially new feature is that the objects are stolen beforehand, then rubbed very thinly with zinc bronze or lightly sheared, after which an aluminum lacquer bronze layer is applied and the lacquer is burned out by heating to about 500 ° C , the aluminum layer being alloyed with the zinc and iron base will.

Es hat sich herausgestellt, daß die Verfahrensstufe des Anreibens oder Scherardisierens der dünnen Zinkzwischenschicht gleichwertig durch Auftragen einer mit Lack vermischten Zinkbronze ersetzt werden kann.It has been found that the step of grinding or shearing the thin zinc interlayer equivalently by application a zinc bronze mixed with varnish can be replaced.

Der Vorteil des neuen abge.ändcrten Verfahrens besteht darin, daß die gleiche Wirkung wie beim Hauptpaterit auf einem neuen und zudem einfacheren Wege erreicht werden kann. Im übrigen spielt sich das Verfahren in genau der gleichen Weise ab wie beim Hauptpatent, und, zwar etwa folgendermaßen-Die Eisengegenstände werden auch hier durch Behandeln mittels Sandstrahlgebläses an ihrer Oberfläche vollständig zunderfrei und rauh gemacht; diese gerauhte Oberfläche wird mit einem dünnen Anstrich von Zinklackbronze überzogen. Auf diesen Anstrich wird nach dem Trocknen ein zweiter von Aluminiumlackbronze aufgebracht. Nachdem das Ganze getrocknet ist, werden die beiden Lackbronzeschichten durch langsames Erhitzen bis auf etwa 500'C ausgebrannt, wobei sieh wieder die Legierung zwischen Aluminium, Zinkund Eisen vollzieht.The advantage of the new, modified procedure is that the same effect as with the main paterite can be achieved in a new and, moreover, simpler way. Otherwise, the process takes place in exactly the same way as in the main patent, namely roughly as follows: Here too, the iron objects are made completely free of scale and rough on their surface by treating them with a sandblasting blower; this roughened surface is covered with a thin coat of zinc lacquer bronze. After drying, a second coat of aluminum lacquer bronze is applied to this coat of paint. After the whole thing has dried, the two layers of lacquer bronze are burned out by slowly heating them up to about 500 ° C , whereby the alloy between aluminum, zinc and iron takes place again.
