Abstract
Description
Die Erfindung betrifft ein Befestigungs- oder Verbindungselement, wie Schraube oder Mutter mit einer Oberflächenbeschichtung. Sie betrifft insbesondere eine Radschrauben für ein Kraftfahrzeug,The The invention relates to a fastening or connecting element, such as Screw or nut with a surface coating. It concerns in particular a wheel bolts for a motor vehicle,
Eine bekannte Oberflächenbeschichtung von korrosionsbeanspruchten Schrauben und Muttern, auch bei Radschrauben im Automobilbau, ist die sogenannte im Tauch- und Einbrennverfahren hergestellte Zinklamellenbeschichtung. Derartige Beschichtungen sind zum Beispiel unter den Handelsnamen Dacromet®, Deltatone® und Geomet®bekannt.A well-known surface coating of corrosion-stressed screws and nuts, also in wheel bolts in the automotive industry, is the so-called zinc flake coating produced in the dipping and baking process. Such coatings are known for example under the trade names Dacromet ®, ® and Deltatone Geomet ®.
Diese Beschichtungsarten besitzen im allgemeinen sehr gute Korrosionsschutzeigen-schaften und in Verbindung mit zusätzlichen Gleitbeschichtungen auch hervorragende Gleiteigenschaften, wodurch die für die Betriebssicherheit der Schraubenverbindung benötigte Montagevorspannkraft erreicht werden kann.These Types of coatings generally have very good anti-corrosion properties and in conjunction with additional Slipcoats also excellent sliding properties, thereby the for the reliability of the bolted connection required assembly preload force can be achieved.
Die derzeit im Automobil-Radschraubenbereich verwendeten Gleitbeschichtungen, zum Beispiel mit dem Handelsnamen „Plus L", bestehen aus einer silikatischen Grundsubstanz, die nicht nur die Reibverhältnisse günstig beeinflusst, sondern auch eine hinreichende Korrosionsbeständigkeit, sogar bei Einwirkung extrem saurer Medien, zum Beispiel flüssigen Felgenreinigern, erzeugt.The Slipcoats currently used in automotive wheel bolts, for example with the trade name "Plus L", consist of a silicate basic substance, not just the friction conditions Cheap influenced, but also a sufficient corrosion resistance, even when exposed to extremely acidic media, such as liquid rim cleaners, generated.
Diese Oberflächenbeschichtung, nämlich ein Zinklamellenüberzug in Verbindung mit silikatischen Gleitmittelüberzügen, hat den Nachteil wenig dekorativen Aussehens. Die Oberflächenfärbung dieser Schrauben unterscheidet sich deutlich sichtbar durch eine wenig dekorative fleckige Graufärbung von dem Hintergrund der verschraubten Bauteile, zum Beispiel von hochglänzenden dekorativen Leichtmetall-Kfz-Rädern.These Surface coating, namely a zinc flake coating in connection with silicate lubricant coatings, has the disadvantage little decorative appearance. The surface color of these screws is different clearly visible through a little decorative mottled graying of the background of the screwed components, for example of high-gloss decorative light metal automotive wheels.
Im Automobilbau ist man deshalb dazu übergegangen, die Köpfe von Radschrauben der bekannten Art mit dünnwandigen Kappen aus austenitischem Stahl zu überziehen. Das Überstülpen von Kappen dieser Art auf den Schraubenkopf bedeutet jedoch eine erhebliche Erhöhung der Herstellkosten der Schrauben.in the Automotive engineering has therefore been transferred to the heads of Wheel bolts of the known type with thin-walled caps austenitic To coat steel. Slipping over caps However, this type of screw head means a considerable increase the cost of the screws.
Die der Erfindung zugrundeliegende Aufgabe ist es, einen kostengünstigen Oberflächenschutz für ein Befestigungselement, insbesondere für eine Radschraube, anzugeben, der zugleich ein dekoratives Aussehen, höchsten Korrosionsschutz und günstige Reibeigenschaften gewährleistet.The The problem underlying the invention is to provide a cost-effective Surface protection for a fastener, especially for a wheel bolt, which at the same time has a decorative appearance, highest Corrosion protection and cheap Ensures frictional properties.
Die Aufgabe wird erfindungsgemäß gelöst durch die Merkmale des Anspruchs 1. weitere bevorzugte Ausgestaltungen sind in den Unteransprüchen niedergelegt.The The object is achieved by the features of claim 1. further preferred embodiments are laid down in the subclaims.
Erfindungsgemäß ist demnach ein Beschichtungsaufbau vorgesehen mit einer metallischen, galvanisch aufgebrachte Legierungsschicht, insbesondere Zink-Nickel-Legierungsschicht, sowie eine zusätzliche silikatische Gleitbeschichtung.Accordingly, according to the invention a coating structure provided with a metallic, galvanic applied alloy layer, in particular zinc-nickel alloy layer, as well as an additional silicate lubricious coating.
Mit diesem Beschichtungsaufbau wird ein dekoratives Äußeres erreicht, das insbesondere durch die Zink-Nickel-Legierungsschicht hervorgerufen wird. Versuche haben gezeigt, dass dieser Beschichtungsaufbau in überraschender Weise zugleich auch einen sehr guten Korrosionsschutz und gute Reibeigenschaften aufweisen. Aufgrund dieser Eigenschaften kann auf den bisher üblichen Einsatz von dekorativen Stahlkappen verzichtet werden, die auf den Schraubenköpfenpf mit dem im Tauch- und Einbrennverfahren aufgebrachten Zinklamellenüberzug aufgestülpt wurden.With This coating structure is achieved a decorative appearance, in particular by the zinc-nickel alloy layer is caused. Have attempts showed that this coating composition surprisingly at the same time also a very good corrosion protection and good friction properties exhibit. Because of these properties may be on the usual Use of decorative steel caps dispensed on the Schraubenköpfenpf were applied with the zinc flake coating applied by dipping and stoving.
Unter dekoratives Aussehen der Schrauben und Muttern, wird insbesondere das farbliche Anpassen an Leichtmetallräder (Aluminiumräder) verstanden. Dies wird durch die Wahl einer geeigneten galvanisch aufgebrachten Zink-Nickel- Legierungsschicht erreicht. Galvanisch aufgebrachte Beschichtungen, zum Beispiel Zink, Chrom- oder Nickelüberzüge oder Überzüge aus Legierungen dieser Metalle, zum Beispiel Zink-Nickel, Zink-Cobalt- oder Zink-Eisenüberzüge, sind an sich bekannt. Diese sind jedoch für den Einsatz bei hochbeanspruchten Bauteilen, insbesondere bei Kfz-Radschrauben, zunächst nicht geeignet, da galvanische, relativ kostengünstige, Oberflächenbeschichtungen die geforderten komplexen Ansprüche nicht erfüllen.Under decorative appearance of the nuts and bolts, in particular understood the color matching to alloy wheels (aluminum wheels). This is done by choosing a suitable electroplated Zinc-nickel alloy layer reached. Galvanically applied coatings, for example zinc, Chrome or nickel coatings or coatings of alloys of these metals, for example zinc-nickel, zinc-cobalt or zinc-iron coatings known in itself. However, these are for use in highly stressed Components, especially in automotive wheel bolts, not initially suitable because galvanic, relatively inexpensive, surface coatings the required complex requirements do not fulfill.
Erst in Kombination mit dem weiterhin vorgesehenen silikatischen Überzug ergeben sich in überraschender Weise die geforderten Eigenschaften hinsichtlich Korrosionsbesändigkeit und Reibeigenschaft. Selbst gegenüber Felgenreinigerflüssigkeiten ist ein wirksamer Korrosionsschutz gegeben. Die günsitgen Reibeigenschaften, das heißt niedrige Reibungszahlen, gewährleisten hierbei, dass eine hohe Montagevorspannkraft auch bei mehrfachem Anziehen erzielt werden kann.First in combination with the further provided silicate coating in a surprise Make the required properties with regard to corrosion resistance and repellent property. Even compared to wheel cleaner fluids given effective corrosion protection. The effective friction properties, this means low friction numbers, ensure In this case, that a high mounting preload even with multiple Tightening can be achieved.
Umfangreiche Entwicklungs- und Versuchsarbeiten haben nämlich gezeigt, dass die insbesondere von der Automobilindustrie für Radschrauben geforderten vorab genannten komplexen Eigenschaften durch die Kombination der galvanischen Zink-Nickel-Legierungsschicht und der silikatischen Gleitbeschichtung, zum Beispiel einer „Plus L"-Beschichtung, in hinreichender Form erzielt werden können.extensive Development and experimental work have shown that the particular from the automotive industry for Wheel bolts required previously mentioned complex properties by the combination of the galvanic zinc-nickel alloy layer and the silicate slip coating, for example a "Plus L" coating, in sufficient form can be achieved.
Diese galvanische Zink-Nickelbeschichtung in Verbindung mit der silikatischen Beschichtung hat zudem den Vorteil wesentlich geringerer Herstellkosten für die Verbindungselemente.This galvanic zinc-nickel coating in conjunction with the silicate coating has In addition, the advantage of significantly lower manufacturing costs for the fasteners.
Vorteilhaft ist darüber hinaus auch, dass bei der vorgeschlagenen galvanischen Beschichtung gegenüber der im Einbrennprozeß hergestellten Zinkamellenbeschichtungen keine beim Gewindewalzen erzeugten Druckeigenspannungen im Schraubengewinde nachträglich verloren gehen können. Druckeigenspannungen verbessern die Belastbarkeit von Schraubengewinden insbesondere bei dynamischer, im Fahrbetrieb von Kraftfahrzeugen aufttretenden, Schwingbeanspruchung nachhaltig. Damit wird die Betriebssicherheit von Kraftfahrzeugen entscheidend verbessert.Advantageous is about it in addition, that in the proposed galvanic coating across from the one produced in the baking process Zinc-flake coatings do not generate residual compressive stresses during thread rolling in the screw thread later can be lost. Compressive stresses improve the load capacity of screw threads especially in dynamic, driving of motor vehicles Occurring, vibration stress sustainable. This is the operational safety decisively improved by motor vehicles.
Versuche haben gezeigt, dass die Montagevorspannkraft von Radschrauben mit einer Zink-Nickel (ZnNi)- und einer zusätzlichen silikatischen „Plus L"-Beschichtung in Alu-Gußrädern selbst nach zwanzigfacher Montage mit einem Anziehdrehmoment von 110 Nm (für die Gewindeabmessung M 12) nur unwesentlich (ca. < 5%) abfällt. Bei den durchgeführten Versuchen lag die Montagevorspannkraft anfangs bei etwa 60 kN und nach der zwanzigsten Montage bei geringfügig unter 60 kN.tries have shown that the mounting preload force of wheel bolts with a zinc-nickel (ZnNi) - and an additional silicate "Plus L" coating in aluminum cast wheels themselves after twentyfold assembly with a tightening torque of 110 Nm (for the Thread size M 12) only insignificantly (approx. <5%) drops. In the experiments carried out The assembly preload was initially at about 60 kN and after Twentieth assembly at slightly below 60 kN.
Zudem haben die beschichteten Radschrauben M 12 ihr ursprüngliches dekoratives Aussehen auch nach der wiederholten mechanischen Beanspruchung durch Montagewerkzeuge und anschließender Felgenreiniger-Korrosionsbeanspruchung zumindet weitgehend behalten.moreover The M 12 coated wheel bolts have their original ones decorative appearance even after repeated mechanical stress due to assembly tools and subsequent rim cleaner corrosion stress largely retained.
