Abstract
Description
Die Erfindung betrifft ein Schichtsystem für die dekorative Beschichtung von galvanisierbaren Werkstücken.The invention relates to a layer system for the decorative coating of galvanizable workpieces.
Derartige Schichtsysteme sind aus dem Stand der Technik bekannt und werden insbesondere in der Automobil- und Möbelindustrie wie auch im Sanitärbereich eingesetzt. Die mögliche Vielfalt der galvanisch-dekorativen Beschichtungen erzeugt dabei den steigenden Trend, nicht nur aus Eisen oder Zink bestehende Grundwerkstoffe, sondern auch eine Vielzahl anderer Basismaterialien, wie z. B. Kunststoffe, mit einer entsprechenden Beschichtung zu versehen. Von besonderem Interesse sind hierbei die mit einer gattungsgemäßen Beschichtung zu erzielenden unterschiedlichen metallischen Matt- und Glanzeffekte. Zum Zwecke des Anlauf- und Korrosionsschutzes werden diese matt- und glanzerzeugenden Schichten in der Regel mit einer Chromschicht abgedeckt, die zumeist ein blau-silbernes Erscheinungsbild aufweist und somit zahlreichen dekorativen Ansprüchen genügt. Zum Schutz eines metallischen Grundwerkstoffes vor Korrosion werden vorzugsweise Kupfer, Nickel und Chrom bzw. Nickel und Chrom aufweisende Schichtsysteme eingesetzt. Unter der Voraussetzung, daß die den Schutzüberzug bildenden Metalle edler als der Grundwerkstoff sind, bietet ein derartiges Schichtsystem insofern einen Korrosionsschutz, als daß Korrosion nur dann auftritt, wenn der Schutzüberzug Inhomogenitäten, wie z. B. Poren oder Riefen, aufweist, die bis zum Grundwerkstoff durchgehen. Diese eingeschränkte Korrosionsbeständigkeit der vorbekannten Schichtsysteme wird jedoch in zunehmendem Maße insbesondere den hohen Anforderungen der Automobilindustrie nicht weiter gerecht.Such layer systems are known from the prior art and are especially in the automotive and furniture industries as well as in the sanitary sector used. The possible variety of electro-decorative coatings creates the rising trend, not just iron or zinc Base materials, but also a variety of other base materials, such as. B. Plastics, to be provided with an appropriate coating. Of Of particular interest are those with a generic coating to achieve different metallic matt and gloss effects. To the For the purpose of tarnishing and corrosion protection, these are matt and glossy layers are usually covered with a chrome layer that mostly has a blue-silver appearance and therefore numerous decorative requirements are sufficient. To protect a metallic base material copper, nickel and chromium or nickel and Chromium layer systems used. Provided that the the protective coating forming metals are more noble than the base material such a layer system to the extent that it only protects against corrosion then occurs when the protective coating inhomogeneities such. B. pores or Grooves, which go through to the base material. This restricted Corrosion resistance of the previously known layer systems is however in increasingly the high demands of Automotive industry no longer fair.
Neben einer Verbesserung der Korrosionsbeständigkeit wird mit der Verwendung einer dekorativen Beschichtung ferner das Ziel verfolgt, einen visuell aufgewerteten Gesamteindruck auszubilden. Hinsichtlich der Farbgebung kann zu diesem Zweck die blau-silbern aussehende Chromdeckschicht durch eine andere galvanische Deckschicht, wie z. B. Zinn, Silber, Gold, Palladium oder Rhodium, ersetzt werden. In nachteiliger Weise kann jedoch mit derartigen Ersatzdeckschichten weder ein guter Korrosionsschutz noch eine hohe Abriebsbeständigkeit erreicht werden.In addition to improving corrosion resistance, the use a decorative coating also pursues the goal of a visual to develop an upgraded overall impression. With regard to the coloring, too the blue-silver-looking chrome top layer by another galvanic top layer, such as B. tin, silver, gold, palladium or rhodium, be replaced. Adversely, however, such Replacement cover layers are neither good corrosion protection nor high Abrasion resistance can be achieved.
Zur Verbesserung der Abriebsbeständigkeit ist es aus dem Stand der Technik bekannt, mittels des Vakuumbeschichtungsverfahrens einen aus Hartstoffpartikeln, wie z. B. Titan- oder Zirkoniumverbindungen, bestehenden Hartstoffüberzug auszubilden und so eine Deckschicht mit höherer Abriebsbeständigkeit zu schaffen. Hierbei lassen sich grundsätzlich als Vakuumbeschichtungsverfahren zum Abscheiden von Hartstoffüberzügen das CVD (chemical vapour deposition)- und das PVD (physical vapour deposition)-Verfahren unterscheiden. Mit Nachteil ist jedoch beiden Verfahrensvarianten gemein, daß die erzeugbaren Hartstoffüberzüge im Bereich üblicher Schichtdicken zu porig sind und daher zum Korrosionsschutz des gesamten Schichtsystems nichts beitragen können. Im Ergebnis wird somit auch ein Schichtsystem, welches als Deckschicht einen Hartstoffüberzug aufweist, den hohen Anforderungen an die Korrosionsbeständigkeit nicht gerecht.To improve the abrasion resistance, it is state of the art known, by means of the vacuum coating process one made of hard material particles, such as B. titanium or zirconium compounds, existing hard material coating form and so a top layer with higher abrasion resistance create. This can basically be done as a vacuum coating process for the deposition of hard material coatings the CVD (chemical vapor deposition) - and distinguish the PVD (physical vapor deposition) process. With disadvantage is common to both process variants that the producible Hard material coatings in the range of conventional layer thicknesses are too porous and therefore for Corrosion protection of the entire layer system can contribute nothing. in the The result is also a layer system, which serves as a top layer Hard material coating has the high demands on the Corrosion resistance does not do it justice.
Aufgabe der Erfindung ist es daher, unter Vermeidung der oben aufgeführten Nachteile ein Schichtsystem bereitzustellen, das hohen Anforderungen an die Korrosionsbeständigkeit gerecht wird, zugleich eine hohe Abriebsbeständigkeit aufweist und zudem eine Vielzahl von Freiheitsgraden hinsichtlich der dekorativen Farbgestaltung bietet.The object of the invention is therefore, while avoiding the above Disadvantages to provide a layer system that places high demands on the Corrosion resistance meets, at the same time high abrasion resistance has and also a variety of degrees of freedom in terms of decorative Color design offers.
Erfindungsgemäß wird diese Aufgabe gelöst durch ein Schichtsystem für die dekorative Beschichtung von galvanisierbaren Werkstücken, gebildet aus einem mittels galvanischer Abscheidung erzeugten und wenigstens eine Glanzschicht und eine diskontinuierliche Chromschicht umfassenden Grundüberzug sowie einem nach dem PVD-Verfahren abgeschiedenen, aus Hartstoffen bestehenden Decküberzug.According to the invention, this object is achieved by a layer system for the decorative coating of galvanizable workpieces, formed from a generated by means of galvanic deposition and at least one gloss layer and a discontinuous chrome layer comprising a basic coating as well a hard material deposited using the PVD process Deck covering.
Mit der erfindungsgemäßen Ausbildung wird erstmals ein Schichtsystem vorgeschlagen, das sowohl hohen Anforderungen an die Korrosionsbeständigkeit gerecht wird als auch eine hohe Abriebsbeständigkeit aufweist. Erreicht wird dies mittels der galvanischen Abscheidung eines eine diskontinuierliche Chromschicht aufweisenden Grundüberzugs zur Erlangung einer hohen Korrosionsbeständigkeit einerseits sowie durch die Ausbildung einer aus Hartstoffen gebildeten Deckschicht zur Erzielung einer hohen Abriebsbeständigkeit andererseits. So haben Untersuchungen, beispielsweise der CASS-Test gezeigt, daß der mit dem erfindungsgemäßen Schichtsystem erzielbare Korrosionsschutz den Anforderungen insbesondere der Automobilindustrie in vollem Umfang gerecht wird. In vorteilhafter Weise hat sich zudem gezeigt, daß das erfindungsgemäße Schichtsystem einen hohen Verschleißschutz sowie eine hohe Abriebsbeständigkeit aufweist.With the training according to the invention, a layer system becomes the first time suggested that both high demands on corrosion resistance is just as good as has a high abrasion resistance. This is achieved by means of the electrodeposition of a discontinuous chrome layer having a basic coating to achieve high corrosion resistance on the one hand and through the formation of a hard material Cover layer to achieve a high abrasion resistance on the other hand. So Studies, for example the CASS test, have shown that the one with the Layer system according to the invention achievable corrosion protection The requirements of the automotive industry in particular are fully met becomes. It has also been shown in an advantageous manner that the inventive Layer system high wear protection as well as high Has abrasion resistance.
Zur Erzielung eines optisch ansprechenden Gesamteindrucks können je nach gewünschter Farbgestaltung unterschiedliche Hartstoffe zur Ausbildung des Decküberzugs verwandt werden. So wird beispielsweise durch die Verwendung von TiC ein anthrazitfarbiger Decküberzug ausgebildet, wohingegen bei einer Mischung aus TiN und ZrN Goldtöne entsprechend dem Goldfarbstandard erreicht werden können. Auch sind in anderen Varianten zahlreiche Farbgebungen, wie beispielsweise rosafarbige oder bläuliche Schichten als Oberflächeneffekte möglich.To achieve a visually appealing overall impression, depending on desired color design different hard materials to form the Deck cover can be used. For example, by using TiC has an anthracite-colored cover, whereas one Mixture of TiN and ZrN gold tones achieved according to the gold color standard can be. There are also numerous colors in other variants, such as for example pink or bluish layers as surface effects possible.
Mit dem erfindungsgemäßen Schichtsystem wird mithin eine galvanisch-dekorative Beschichtung bereitgestellt, die die heutigen Anforderungen an Korrosions- und Verschleißschutz erfüllt und zugleich zahlreiche Möglichkeiten der dekorativen Farbgestaltung bietet.The layer system according to the invention thus becomes a galvanically decorative one Coating provided that meets today's requirements for corrosion and Wear protection fulfilled and at the same time numerous possibilities of decorative Color design offers.
Gemäß einem Merkmal der Erfindung ist die diskontinuierliche Chromschicht ein mikrorissiger oder mikroporiger Chromüberzug. Für die Ausbildung eines mikroporigen Chromüberzugs ist es erforderlich, zunächst einen Nickeldispersionsüberzug auf der Oberfläche des Werkstücks auszubilden und diesen anschließend mit einer Chromschicht zu bedecken. Als Folge der Ausbildung des Nickeldispersionsüberzugs entsteht ein mikroporiger Chromüberzug. Eine direkte mikroporige Verchromung ist bisher nicht möglich. Im Gegensatz hierzu können mikrorissige Chromüberzüge im einstufigen Verfahren oder nach dem Doppelverchromverfahren auf jedem Nickelüberzug direkt erzeugt werden. Auch kann die mikrorissige Verchromung über die Abscheidung von Rißnickelüberzügen erzeugt werden. Dabei weist gegenüber dem ein- oder zweistufigen mikrorissigen Verchromen der Rißnickelelektrolyt eine bessere Rißtiefensteuerung auf, was zu einer gleichmäßigeren mikrorissigen Verchromung führt. In vorteilhafter Weise bieten als diskontinuierliche Chromschicht sowohl der mikrorissige als auch der mikroporige Chromüberzug einen ausgezeichneten Korrosionsschutz, der hohen Anforderungen gerecht wird und gegenüber herkömmlich hergestellten Schichtsystemen eine erhebliche Verbesserung darstellt.According to a feature of the invention, the discontinuous chrome layer is one micro-cracked or micro-porous chrome plating. For training one microporous chrome plating, it is necessary to start with one Form nickel dispersion coating on the surface of the workpiece and then cover it with a chrome layer. As a result of The formation of the nickel dispersion coating creates a microporous Chrome plating. A direct microporous chrome plating has not been possible so far. in the In contrast, micro-cracked chrome coatings can be applied in a one-step process or produced directly on any nickel plating using the double chrome process become. The micro-cracked chrome plating can also be carried out by the deposition of Crackle nickel coatings are produced. Here points towards the one or two-stage micro-cracked chrome plating the cracked nickel electrolyte a better Crack depth control on, resulting in a more uniform micro-cracked chrome plating leads. Advantageously, both offer the discontinuous chrome layer micro-cracked as well as the micro-porous chrome coating an excellent Corrosion protection that meets high requirements and against conventionally produced layer systems a significant improvement represents.
Gemäß einem weiteren Merkmal der Erfindung ist die Glanzschicht ein Glanznickel- oder Perlglanznickelüberzug, wodurch sich in vorteilhafter Weise Glanz- oder Mattoberflächeneffekte einstellen und auf den optischen Gesamteindruck abstimmen lassen. So ist beispielsweise mit der Ausbildung eines Perlglanznickelüberzugs eine blendarme Vernickelung erreichbar, die im Gegensatz zur Glanzvernickelung eine Oberfläche mit einem matten Seidenglanz ausbildet.According to a further feature of the invention, the gloss layer is a Bright nickel or pearlescent nickel coating, which is advantageous Set gloss or matte surface effects and on the optical Have the overall impression coordinated. For example, with the training one Pearlescent nickel plating achieves a low-glare nickel plating, which in Contrary to the gloss nickel plating, a surface with a matt silk gloss trains.
Gemäß einem weiteren Merkmal der Erfindung weist der Grundüberzug zwischen Glanzschicht und diskontinuierlicher Chromschicht eine weitere Nickelschicht auf. Diese Nickelschicht ist in vorteilhafter Weise ein Nickeldispersionsüberzug und dient der Ausbildung eines mikroporigen Chromüberzugs. So wird durch den Nickeldispersionsüberzug eine Oberfläche mit eingelagerten, nicht leitenden Partikeln geschaffen, was dazu führt, daß bei einem Aufbringen eines Chromüberzugs an denjenigen Stellen der eingelagerten Partikel Poren im Chromüberzug ausgebildet werden, wodurch ein mikroporiger Chromüberzug erzeugt wird. Besonderer Vorteil eines derartigen Chromüberzugs ist die hohe Korrosionsbeständigkeit. According to a further feature of the invention, the basic coating has between Glossy layer and discontinuous chrome layer on another nickel layer. This nickel layer is advantageously a nickel dispersion coating and is used to form a microporous chrome coating. So through the Nickel dispersion coating a surface with embedded, non-conductive Particles created, which leads to the fact that when an Chromium coating at those points of the embedded particles in the pores Chrome plating can be formed, creating a microporous chrome plating is produced. A particular advantage of such a chrome coating is the high one Corrosion resistance.
Gemäß einem weiteren Merkmal der Erfindung weist der Grundüberzug in Dickenrichtung unterhalb der Glanzschicht eine dritte Nickelschicht auf, wobei diese in vorteilhafter Weise ein aus schwefelfreiem, kolumnarem Nickel bestehender Überzug ist. Auf diese Weise wird in Verbindung mit dem Glanznickel- oder Perlglanznickelüberzug und dem Nickeldispersionsüberzug ein Mehrfachnickelüberzugssystem ausgebildet, das eine besonders hohe Korrosionsbeständigkeit aufweist.According to a further feature of the invention, the basic coating in Thickness direction below the gloss layer on a third nickel layer, wherein this advantageously consists of sulfur-free, columnar nickel existing coating is. This way, in conjunction with the Bright nickel or pearlescent nickel coating and the nickel dispersion coating Multiple nickel plating system designed, which is a particularly high Has corrosion resistance.
Gemäß einem weiteren Merkmal der Erfindung weist der Grundüberzug eine in Dickenrichtung zu unterst angeordnete Kupferschicht auf.According to a further feature of the invention, the basic coating has an in Thickness direction to the bottom arranged copper layer.
Gemäß einem weiteren Merkmal der Erfindung werden als Hartstoffe vorzugsweise Elemente der IV. Nebengruppe, insbesondere Titan, Zirkonium und Hafnium, Kombinationen derselben und/oder deren Nitride, Oxide oder Carbide verwendet. Die Verwendung derartiger Hartstoffe bietet in vorteilhafter Weise die Möglichkeit, einen Decküberzug auszubilden, der eine hohe Abriebsbeständigkeit aufweist und mithin einen hohen Verschleißschutz bietet. Zudem kann über die Wahl der verwendeten Hartstoffe die farbige Gestaltung des Schichtsystems gewählt und abgestimmt werden. Das Aufbringen des Decküberzugs geschieht dabei mittels Gasphasenabscheidung, wobei zwischen dem CVD(chemical vapour deposition)- und dem PVD(physical vapour deposition)-Verfahren unterschieden werden kann. Wesentliches Merkmal der PVD-Verfahrens ist hierbei, daß eine metallische Kathode als Target verdampft wird und sich dieser Metalldampf wiederum unter kontrolliertem Zusatz von Reaktionsgasen auf der Werkstoffoberfläche, beispielsweise als Nitrid oder Carbit, abscheidet.According to a further feature of the invention are called hard materials preferably elements of subgroup IV, in particular titanium, zirconium and Hafnium, combinations thereof and / or their nitrides, oxides or carbides used. The use of such hard materials advantageously offers the Possibility to form a top coat that has a high abrasion resistance and therefore offers high wear protection. You can also use the Choice of hard materials used the colored design of the layer system be chosen and coordinated. The deck covering is applied by means of gas phase separation, whereby between the CVD (chemical vapor deposition) - and the PVD (physical vapor deposition) process can be distinguished. An essential feature of the PVD process is here that a metallic cathode is evaporated as a target and this Metal vapor in turn with the controlled addition of reaction gases on the Deposits material surface, for example as nitride or carbite.
Insgesamt wird mit dem erfindungsgemäßen Schichtsystem eine Beschichtungstechnologie vorgeschlagen, mit der eine Vielzahl unterschiedlicher dekorativer Beschichtungen hinsichtlich Glanz- oder Matteffekte sowie hinsichtlich der Farbgebung möglich sind und die zugleich höchsten Anforderungen an Korrosions- und Abriebsbeständigkeit gerecht wird.Overall, with the layer system according to the invention Coating technology proposed using a variety of different decorative coatings with regard to gloss or matt effects and with regard to the coloring are possible and at the same time the highest demands Corrosion and abrasion resistance.
