Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung einer strukturierten Oberfläche auf einem aus Kupfer oder einer Kupferlegierung bestehendem Halbzeug, insbesondere auf ge walzten Bändern oder Blechen mit einer Dicke von 0,4 bis 1 mm. Ferner betrifft die Erfindung die Verwendung von struk turiertem bandförmigem Halbzeug im Baubereich.The invention relates to a method for producing a textured surface on a copper or a Copper alloy existing semi-finished product, especially on ge rolled strips or sheets with a thickness of 0.4 to 1 mm. Furthermore, the invention relates to the use of struk tured ribbon-shaped semi-finished product in the construction area.
Unter normalen atmosphärischen Bedingungen bildet sich auf der Oberfläche von metallblankem Kupfer eine festhaftende und beständige Deckschicht, die sich infolge der Reaktion des Kupfers mit Feuchtigkeit und/oder Luftsauerstoff teilweise erst mit großer Zeitverzögerung zu einer gleichmäßigen Braun färbung weiter entwickelt.Forms under normal atmospheric conditions the surface of bare metal has a firmly adhering and stable top layer, which is due to the reaction of the Copper with moisture and / or atmospheric oxygen partially only with a great time delay to an even brown coloring developed further.
Für die unterschiedlichen Anwendungsfälle, insbesondere im Baubereich, besteht jedoch vielfach der Wunsch nach dekora tiven Oberflächen, deren Farbgebung individuell einstellbar und von einer Bewitterung oder einer Behandlung mit chemi schen Lösungen unabhängig ist. Ferner soll sich das Aussehen der Oberfläche weder durch Handhabung bei der Montage noch durch Bewitterung wesentlich verändern.For the different applications, especially in Construction area, but there is often a desire for decora tive surfaces, the colors of which can be individually adjusted and weathering or treatment with chemi solutions is independent. Furthermore, the appearance should the surface neither by handling during assembly nor change significantly through weathering.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzu geben, mit dem das Erscheinungsbild der Oberfläche von aus Kupfer oder Kupferlegierungen bestehendem Halbzeug verbessert werden kann. The invention has for its object to provide a method with which the appearance of the surface of from Copper or copper alloys of existing semi-finished products improved can be.
Diese Aufgabe wird erfindungsgemäß durch die Kombination der im Anspruch 1 angegebenen Verfahrensmaßnahmen gelöst. Vor teilhafte Weiterbildungen des erfindungsgemäßen Verfahrens sind durch die Merkmale der Unteransprüche 2 bis 6 gekenn zeichnet. Bevorzugte Anwendungsgebiete für oberflächenver edeltes bandförmiges Halbzeug sind in den Ansprüchen 7 und 8 angegeben.This object is achieved by the combination of Process measures specified in claim 1 solved. Before partial further developments of the method according to the invention are characterized by the features of subclaims 2 to 6 draws. Preferred areas of application for surface noble band-shaped semi-finished products are in claims 7 and 8 specified.
Mit Hilfe der Maßnahmen des erfindungsgemäßen Verfahrens ge lingt es in überraschend einfacher Weise eine strukturierte Oberfläche auf aus Kupfermaterial bestehendem Halbzeug zu er zeugen, die vorzugsweise ein mattes Aussehen aufweist und in Abhängigkeit von dem jeweils verwendeten thermischen Spritz pulvermaterial eine breite Palette von unterschiedlichen Farbgebungen auf dem Basiswerkstoff ermöglicht.With the help of the measures of the method according to the invention succeeds in a surprisingly simple way a structured Surface on semi-finished products made of copper material testify, which preferably has a matt appearance and in Dependence on the thermal spray used in each case powder material a wide range of different Colorings on the base material made possible.
So erhält beispielsweise die Oberfläche eines durch thermi sches Spritzen von Aluminiumpulverteilchen beschichteten Kup ferblechs eine sehr dekorative mattsilberfarbende Oberflä chenstruktur, die einen ausgezeichneten Schutz gegen mecha nische und chemische Beeinträchtigungen aufweist. Derartige mit Aluminiumpulverteilchen beschichtete Trägerbleche eignen sich insbesondere für die Verkleidung von Decken und Wänden für den anspruchsvollen Innenausbau von Gebäuden. Auch in Verbindung mit Wärmetaucherelementen können die beschichteten Trägerbleche mit besonderem Vorteil eingesetzt werden, da sie durch ihre größere Oberfläche den Wirkungsgrad von Wärmetau schern für die Raumklimatisierung erhöhen.For example, the surface is given one by thermi spraying of aluminum powder coated copper ferblechs a very decorative matt silver colored surface structure that provides excellent protection against mecha niche and chemical impairments. Such Carrier sheets coated with aluminum powder particles are suitable are particularly suitable for cladding ceilings and walls for the demanding interior of buildings. Also in The coated can be combined with heat exchanger elements Carrier sheets are used with particular advantage since they due to their larger surface, the efficiency of heat accumulation increase scissors for room air conditioning.
Anhand eines Ausführungsbeispiels wird die Erfindung im fol genden noch näher erläutert.Using an exemplary embodiment, the invention in fol reasons explained in more detail.
Die Oberfläche eines kaltgewalzten und gegebenenfalls entfet teten Bands aus SF-Cu mit einer Dicke von 0,7 mm und einer Breite von 1000 mm wurde mittels einer Schleifvorrichtung gleichmäßig in Vorschubrichtung des Bands (längs) geschlif fen. Für die mechanische Vorbehandlung der Bandoberfläche wurden Schleifbänder mit 40iger und 60iger Körnung einge setzt. Die mittlere Rauhtiefe der geschliffenen Oberfläche betrug nach dem Schleifvorgang etwa 6 µm. Geeignet ist eine mittlere Rauhtiefe von 0,5 bis 20 µm. Auf eine derart gezielt aufgerauhte Bandoberfläche wurde dann eine thermische Be schichtung mit Metallpulverteilchen, beispielsweise mit Kup ferteilchen, aufgebracht. Für die thermische Beschichtung stand eine Flammspritzpistole zur Verfügung, die als Trans portgas für die Metallpulverteilchen vorzugsweise ein inertes Gas verwendet.The surface of a cold rolled and possibly defatted tied bands of SF-Cu with a thickness of 0.7 mm and one Width of 1000 mm was made using a grinder ground evenly in the direction of feed of the belt (lengthways) fen. For the mechanical pretreatment of the belt surface sanding belts with 40 and 60 grit were inserted puts. The average surface roughness of the ground surface was about 6 µm after the grinding process. One is suitable average roughness from 0.5 to 20 µm. Targeted at such a roughened belt surface was then a thermal Be layering with metal powder particles, for example with cup ferpartchen, applied. For thermal coating a flame spray gun was available, which was used as a trans port gas for the metal powder particles preferably an inert Gas used.
Die Auftragsschichten hatten eine Dicke von etwa 0,1 mm. Die Beschaffenheit der aufgespritzten Beschichtung ist matt und erweist sich auch optisch als ausreichend deckend.The application layers had a thickness of approximately 0.1 mm. The The texture of the sprayed coating is matt and also proves to be sufficiently opaque optically.
Eine metallographische Untersuchung der Mikrostruktur der Auftragsschicht zeigte eine gute Teilchenbindung der aufge spritzen Metallteilchen mit dem Trägerwerkstoff.A metallographic examination of the microstructure of the Application layer showed good particle binding of the applied spray metal particles with the carrier material.
