Description
Verbund-Werkstoff Es ist bekannt, eiserne Gegenstände mit Aluminium zu plattieren, um die Festigkeit des Eisens mit der guten Korrosionsbeständigkeit des Aluminiums zu verbinden und insbesondere ein Rosten der Eisenoberfläche zu verhindern.Composite material It is known to make iron objects with aluminum to plate to the strength of iron with the good corrosion resistance of the aluminum and in particular to prevent rusting of the iron surface.
Beim Aufplattieren von Aluminium auf Eisen durch Warmwalzen und Rekristallisation bildet sich an der Verbindungsfläche eine spröde Schicht aus Eisenaluminium, die bei Verformungen des Verbundwerkstoffes häufig zu Rißbildungen an der Verbindungsfläche führt. Es ist bekannt, dieser Schwierigkeit dadurch zu begegnen, daß dem Aluminium etwa 10/o Silizium zugesetzt wird. Die Bildung der spröden Zwischenschicht wird dadurch weitgehend unterbunden.When plating aluminum on iron by hot rolling and recrystallization A brittle layer of iron-aluminum forms on the joint surface, which when the composite material is deformed, cracks often form on the connection surface leads. It is known to counter this difficulty in that the aluminum about 10 / o silicon is added. The formation of the brittle intermediate layer will thereby largely prevented.
Es ist ferner bekannt, eine Zwischenschicht aus Silber zwischen dem eisernen Kernwerkstoff und der Aluminiumplattierschicht vorzusehen. Auch durch diese Maßnahme wird die Bildung der spröden Zwischenschicht aus Eisenaluminium verhindert.It is also known to have an intermediate layer of silver between the to provide iron core material and the aluminum clad layer. Also through this Measure prevents the formation of the brittle intermediate layer made of iron-aluminum.
Es ist vorgeschlagen worden, eiserne Gegenstände in an sich bekannter Weise auch mit Reinstaluminium oder Legierungen von Reinstaluminium mit Zusätzen bis zu 3 0/o Magnesium, welche gegebenenfalls noch weitere Zusätze, wie z. B. Zink bis zu 3 % oder Beryllium bis zu 0,50/o, die die Glänzbarkeit bzw. die anodische Oxydierbarkeit nicht wesentlich beeinträchtigen, enthalten können, zu plattieren, da sich diese Legierungen in hervorragender Weise durch chemische oder elektrochemische Verfahren glänzen oder anodisch oxydieren lassen. Durch ein Zulegieren von Silizium zu diesen Plattierwerkstoffen zum Zwecke einer Unterbringung der sich beim Plattieren bildenden spröden Schicht von Eisenaluminium wird jedoch sowohl die Glänzbarkeit als auch die anodische Oxydierbarkeit stark beeinträchtigt.It has been suggested to use iron objects in themselves Also with pure aluminum or alloys of pure aluminum with additives up to 3 0 / o magnesium, which may contain other additives, such as. B. zinc up to 3% or beryllium up to 0.50 / o, the glossiness or the anodic Not significantly impair oxidizability, may contain, to plate, because these alloys are excellent by chemical or electrochemical Process shine or oxidize anodically. By adding silicon as an alloy to these cladding materials for the purpose of accommodating the plating However, the brittle layer of aluminum iron that forms both the glossiness as well as the anodic oxidizability severely impaired.
Die Verwendung einer Zwischenschicht aus Silber wäre zwar grundsätzlich möglich, ist jedoch höchst unwirtschaftlich und bedingt außerdem mancherlei technologische Nachteile des Verbundwerkstoffes, z. B. Zerfallserscheinungen des mit Eisen und Aluminium durch Diffusion angereicherten Silbers bei leicht gehobenen Temperaturen. Um diese Schwierigkeiten zu beseitigen, wird nach der Erfindung zwischen dem eisernen Kernwerkstoff und dem Plattierwerkstoff aus Reinstaluminium oder einer Legierung aus Reinstaluminium und bis 5 % Magnesium eine Zwischenplattierung aus einer Aluminium-Silizium-Legierung mit 0,5 bis 2% Silizium angebracht.The use of an intermediate layer of silver would be fundamental possible, but it is highly uneconomical and also requires a variety of technological options Disadvantages of the composite, e.g. B. Disintegration of the with iron and Aluminum through diffusion enriched silver at slightly elevated temperatures. In order to eliminate these difficulties, according to the invention between the iron Core material and the cladding material made of pure aluminum or an alloy made of pure aluminum and up to 5% magnesium, an intermediate cladding made of an aluminum-silicon alloy attached with 0.5 to 2% silicon.
Ein der Erfindung entsprechender Verbundwerkstoff wird beispielsweise dadurch hergestellt, daß ein Eisenblech zunächst in bekannter Weise mit einer Legierung aus Reinaluminium und. 1 % Silizium plattiert wird und auf diesen Werkstoff in einem zweiten Arbeitsgang ebenfalls in bekannter Weise Reinstaluminium oder eine Legierung aus Reinstaluminium und 10/o Magnesium aufplattiert wird.A composite material according to the invention is for example produced in that an iron sheet first in a known manner with an alloy made of pure aluminum and. 1% silicon is plated and on this material in one second step, also in a known manner, pure aluminum or an alloy made of pure aluminum and 10 / o magnesium is plated.
Man kann erfindungsgemäß auch in der Weise verfahren, daß im ersten Arbeitsgang ein Verbundwerkstoff aus einer Aluminiumlegierung mit 10/o Silizium und aus Reinstaluminium oder einer Legierung aus Reinstaluminium und 10/o Magnesium hergestellt und in einem zweiten Arbeitsgang dieser Verbundwerkstoff auf ein Eisenblech aufplattiert wird, so daß eine Zwischenplattierung aus der Aluminium-Silizium-Legierung entsteht.You can proceed according to the invention in such a way that in the first Operation a composite material made of an aluminum alloy with 10 / o silicon and of pure aluminum or an alloy of pure aluminum and 10 / o magnesium produced and in a second step this composite material on an iron sheet is plated on, so that an intermediate plating from the aluminum-silicon alloy arises.
Das Dickenverhältnis zwischen den drei miteinander verbundenen Werkstoffen richtet sich nach dem Verwendungszweck, jedoch ist die Mindestdicke der Zwischenplattierung in jedem Falle so groß zu wählen, daß die Bildung einer spröden Schicht aus Eisenaluminium verhindert wird.The thickness ratio between the three interconnected materials depends on the intended use, but the minimum thickness of the intermediate cladding is in any case to be chosen so large that the formation of a brittle layer of iron-aluminum is prevented.
Der so hergestellte Verbundwerkstoff wird in bekannter Weise geglänzt oder anodisch oxydiert.The composite material produced in this way is polished in a known manner or anodically oxidized.
