Description
Um auf Schwermetallen, wie Eisen, Kupfer usw., beliebige, besonders dünne Überzüge aus anderen Metallen herzustellen, werden hauptsächlich zwei Wege benutzt, und zwar a) der galvanische Niederschlag,In order to apply any particularly thin coatings on heavy metals such as iron, copper, etc. To manufacture from other metals, two main routes are used, namely a) the galvanic precipitation,
b) der durch mechanische Metallplattierung.b) that by mechanical metal plating.
Versucht man nun aber Aluminium als GrundmetaH mit einem besonders dünnen Überzug aus Schwermetallen zu versehen, so bereiten diese vorerwähnten Wege erhebliche Schwierigkeiten:But if you try aluminum as a basic metal with a particularly thin one To provide a coating of heavy metals, the above-mentioned ways prepare considerable Trouble:
a) Das Verhalten von Aluminium im galvanischen Bad ist bekanntlich derartig, daß bis heute noch kein einwandfreier haltbarer Überzug auf einfache und billige Weise möglich ist.a) The behavior of aluminum in the electroplating bath is known to be such that to this day, a flawless, durable coating has not been possible in a simple and cheap way is.
b) Wenn ein Metall mit einem besonders dünnen Überzug eines anderen Metalles auf dem Wege der Plattierung versehen wird, so gelingt das leicht, wenn das Überzugsmetall weicher und dehnbarer ist, als das zu überziehende Grundmetall, wie z. B. Kupfer mit Feinsilber oder Eisen mit Kupfer, Messing o. dgl. Im umgekehrten Falle jedoch treten erhebliche Schwierigkeiten auf, wenn ein weiches, dehnbares Metall mit einem dünnen Überzug eines weniger dehnbaren, harten plattiert werden soll, weil die im Verhältnis zum weichen Kern dünnen, harten Überzugsmetalle hierbei zerdehnt werden.b) When a metal with a particularly thin coating of another metal on is provided by the way of plating, this is easy if the coating metal is softer and more ductile than the base metal to be coated, e.g. B. copper with Fine silver or iron with copper, brass or the like. In the opposite case, however, occur Significant difficulties arise when a soft, ductile metal with a thin Plating a less ductile, hard plating because the proportion Here, thin, hard coating metals are expanded to form a soft core.
Man hat bereits versucht, diesem Übelstand durch Bedeckung des härteren Überzugsmetalles mit einer losen Schicht eines weicheren Metalles zu begegnen oder das weichere Kernmetall mittels aufgelegter glühender Platten nur an der Oberfläche zu erhitzen, damit dieses im Innern seine ursprüngliche Härte behält, während das härtere Überzugsmetall vollständig erhitzt wird, d. h. durch unterschiedliche Erwärmung die Härteunterschiede auszugleichen. Nach einer weiteren Methode sollen die beim Walzen von Doppelmetall aus Komponenten verschiedener Festigkeit und Bildsamkeit auftretenden Streckungsunterschiede durch größere Umfangsgeschwin- digkeit der auf das weniger bildsame Metall wirkenden Walzen aufgehoben werden.Attempts have already been made to remedy this problem by covering the harder coating metal counter with a loose layer of a softer metal or the softer core metal only to heat the surface by means of applied glowing plates, so that this internally retains its original hardness while the harder clad metal is fully heated, d. H. through different Heating to compensate for the differences in hardness. Another method should be used when rolling double metal Differences in elongation arising from components of different strength and malleability due to greater circumferential speeds of the rollers acting on the less malleable metal.
Die vorliegende Erfindung ermöglicht nun auf einfachere und sichere Weise die Herstellung von besonders dünnen Schwermetallüberzügen auf dem weicheren Aluminium dadurch, daß dem als Grundmetall verwendeten Aluminium die jeweilige Dehnung und Streckfähigkeit des Überzugsmetalles dadurch gegeben wird, daß man es mit anderen Metallen, wie Kupfer, Magnesium, Zink, Eisen, Antimon usw., im entsprechenden Verhältnis legiert.The present invention now enables production in a simpler and safer manner of particularly thin heavy metal coatings on the softer aluminum due to the fact that the aluminum used as the base metal the respective elongation and extensibility of the coating metal are thereby given that you can do it with other metals, such as copper, magnesium, zinc, iron, Antimony, etc., alloyed in the appropriate ratio.
