Patentirt im Deutschen Reiche vom 21. April 1898 ab.Patented in the German Empire on April 21, 1898.
Den Gegenstand der vorliegenden Erfindung bildet ein Verfahren zum Plattiren von Aluminium auf galvanischem Wege, wodurch es möglich ist, aus Aluminium hergestellte Gegenstände nicht allein zu vergolden und zu versilbern, sondern dieselben auch mit einem Ueberzuge irgend eines beliebigen anderen Metalles, wie Nickel, Kobalt, Kupfer u. s. w., zu überziehen, so dafs das Verfahren im Wesentlichen in einer Anwendung des gewöhnlichen galvanoplastischen Verfahrens aus Aluminium besteht.The subject of the present invention is a process for plating aluminum by galvanic means, which makes it possible to produce objects made of aluminum not only to gold and silver, but also with a coating of any other Metal, such as nickel, cobalt, copper and so on, so that the process in the Essentially in an application of the usual electroplating process from aluminum consists.
Nur mit Schwierigkeiten war es bisher möglich, Aluminium zu vergolden oder zu versilbern, und noch viel weniger gelingt das Ueberziehen mit anderen Metallen. Die bis jetzt bekannten Methoden zum Plattiren bewirken dasselbe fast ausschliefslich durch Aufbringen einer Gold- oder Silberlösung in Gegenwart eines Reductionsmittels, wie schwefliger Säure (Verfahren von Deville), von Natriumhyposulfat (Verfahren von Tissier), ohne dafs sich diese Methoden zur galvanischen Versilberung oder Vergoldung bisher hätten anwenden lassen. Auch sonst zeigen jene Bäder eine von den zur galvanischen Versilberung und Vergoldung anderer Metalle bisher angewendeten durchaus abweichende Zusammensetzung. Nach der vorliegenden Erfindung dagegen sind die zum galvanischen Plattiren anderer Metalle angewendeten Bäder direct auch für Aluminium verwendbar.Up to now it has only been possible to gold or silver plate aluminum with difficulty, and coating with other metals is still less successful. The methods known up to now for plating are effective the same almost exclusively by applying a gold or silver solution in the presence of a reducing agent such as sulphurous Acid (Deville method), sodium hyposulphate (Tissier method), without these methods of galvanic silver-plating or gold-plating having hitherto been used let apply. Otherwise, those baths show one of those for galvanic silver plating and gold plating of other metals previously used quite different composition. According to the present invention on the other hand, the baths used for galvanic plating of other metals can also be used directly for aluminum.
Dies wird nun nach dem vorliegenden Verfahren dadurch erreicht, dafs man den galvanischen Bädern einen Zusatz von Dioxybenzolverbindungen, wie Pyrocatechin oder Hydrochinon oder einer Mischung derselben, giebt. Indem diese organischen Reductionsmittel auch auf das zu plattirende Aluminium selbst einwirken, ermöglichen sie die directe Verbindung desselben mit dem durch den elektrolytischen Procefs niedergeschlagenen Metall, ähnlich den bei den bisherigen, ohne galvanische Mittel ausgeführten Methoden angewendeten anorganischen Reductionsmitteln. Dadurch wird es auch möglich, der Methode eine viel gröfsere Ausdehnung als bisher zu geben, so dafs dadurch sich jegliches Metall auf Aluminium niederschlagen läfst.According to the present method, this is achieved by using the galvanic Baths contain an addition of dioxybenzene compounds, such as pyrocatechin or hydroquinone or a mixture of these. By using these organic reducing agents too act on the aluminum to be plated itself, they enable the direct connection the same with the metal precipitated by the electrolytic process, similar to the inorganic methods used so far without galvanic agents Reducing agents. This also makes it possible to give the method a much greater extension than before, so that by doing so any metal can condense on aluminum.
Dieses Verfahren bietet aufser seiner allgemeinen Anwendbarkeit noch den Vortheil, dafs es sich wie jedes galvanische Verfahren schneller und mit viel gröfserer Sicherheit ausführen läfst als die oben erwähnten, eine gewisse chemische Kenntnifs und Geschicklichkeit voraussetzenden nicht elektrolytischen Methoden.In addition to its general applicability, this procedure has the advantage that like any galvanic process, it can be carried out faster and with much greater security as those mentioned above, presupposes a certain chemical knowledge and skill non-electrolytic methods.
Es lassen sich nach diesem Verfahren beliebige Schattirungen von höchstem Glanz bis zur mattesten Fläche erhalten, was bisher ebenfalls nicht gelang.Any desired shades from the highest gloss to to the mattest surface, which has also not been achieved so far.
