Description

"Beschichtunqssvstem" "Coating system"
Die Erfindung betrifft ein Beschichtungssystem zur Beschichtung von Bauteilen mit einem insbesondere für Befestigungselemente für Räder und Rollen. 5The invention relates to a coating system for coating components with a particularly for fasteners for wheels and rollers. 5
Zur Verbesserung der Gleiteigenschaften von Oberflächen bzw. zur Verringerung der Oberflächenrauheit ist der Einsatz von Trockenschmierstoffen als sogenanntes anti-friction-coating bekannt. Hierbei werden beispielsweise PTFE- oder graphithaltige Beschichtungssysteme eingesetzt. Ebenso ist es l o bekannt Systeme auf MoS2-Basis einzusetzen.To improve the sliding properties of surfaces or to reduce the surface roughness, the use of dry lubricants is known as a so-called anti-friction coating. For example, PTFE or graphite-containing coating systems are used. It is also known to use MoS2-based systems.
Ferner ist es bekannt, die Oberfläche, auf die der Trockenschmierstoff aufgebracht werden soll vorzubehandeln, um die Korrosionseigenschaften zu verbessern. Zur Verbesserung der Hafteigenschaften des Trockenschmier- 15 Stoffs auf dem Bauteil bzw. auf der Unterlage wird im Stande der Technik eine Zink- oder Manganphosphatschicht als Unterlage verwendet, die eine Erhöhung der Oberflächenrauheit bewirkt.It is also known to pretreat the surface to which the dry lubricant is to be applied in order to improve the corrosion properties. In order to improve the adhesive properties of the dry lubricant substance on the component or on the base, a zinc or manganese phosphate layer is used as the base in the prior art, which causes an increase in the surface roughness.
In allen bekannten Fällen sind jedoch sowohl die Hafteigenschaften als auch 20 die Korrosionseigenschaften bekannter Systeme nicht zufriedenstellend. Insbesondere für Schrauben besteht im Stande der Technik das Problem eines nicht reproduzierbaren Gleitverhaltens. Dieses Problem ist besonders gravierend im Bereich der Rad-Schrauben für Kraftfahrzeuge. Aufgrund der nicht eindeutig definierten Gleiteigenschaften lassen sich aus dem gewähl- 25 ten Drehmoment keine reproduzierbaren Einschraubeigenschaften herleiten.In all known cases, however, both the adhesive properties and the corrosion properties of known systems are unsatisfactory. For screws in particular, the prior art has the problem of a non-reproducible sliding behavior. This problem is particularly serious in the area of wheel bolts for motor vehicles. Due to the non-clearly defined sliding properties, no reproducible screw-in properties can be derived from the selected torque.
Dabei ist ein in vorgegebenen Grenzen einzustellendes Verhältnis zwischen Anziehdrehmoment und Vorspannkraft erwünscht. Die Vorspannkraft liegt aber im Stande der Technik bei einem festgelegten Anziehdrehmoment der 30 Verbindungselemente in einer gewissen Variationsbreite. Diese Variationsbreite wird durch Einsatz unterschiedlicher Werkstoffe (Leichtmetalllegierungen, vorzugsweise Aluminium- oder Magnesiumlegierungen oder Stahl) verschärft. Ebenfalls problematisch ist die mechanische Belastung durch eine Mehrfachmontage sowie die in der Praxis auftretenden physikalischen Schlag und Temperatureinwirkungen.A relationship between the tightening torque and the preload force that is to be set within predetermined limits is desired. In the prior art, however, the pretensioning force is within a certain range of variation with a fixed tightening torque of the 30 connecting elements. This range of variation is exacerbated by the use of different materials (light metal alloys, preferably aluminum or magnesium alloys or steel). The mechanical stress caused by multiple assembly and the physical impact and temperature effects that occur in practice are also problematic.
Ein weiteres Problem, welches im Bereich der Kfz-Radschrauben besonders zum Tragen kommt, ist die Korrosion der Schraube, die insbesondere an ihren nicht am Gewinde anliegenden Flanken einem Angriff von Feuchtigkeit ausgesetzt ist.Another problem, which is particularly important in the field of motor vehicle wheel bolts, is the corrosion of the bolt, which is exposed to moisture attack, particularly on its flanks that are not in contact with the thread.
Der Erfindung liegt somit das Problem zugrunde, ein Beschichtungssystem zur Beschichtung von Bauteilen mit Trockenschmierstoffen zu schaffen, daß erheblich verbesserte Haftungseigenschaften, eine erhöhte Korrosionsbeständigkeit und darüberhinaus eine hohe Chemikalienbeständigkeit auf- weist.The invention is therefore based on the problem of creating a coating system for coating components with dry lubricants which has considerably improved adhesion properties, increased corrosion resistance and, moreover, high chemical resistance.
Das Problem wird gelöst durch ein Beschichtungsystem, bei dem der Trok- kenschmierstoff auf einer Zink/Nickel-Schicht aufgebracht ist, die zuvor mit einem Oxidationsmittel behandelt wurde. Alternativ kann der Trocken- Schmierstoff auch auf eine Konversionsschicht aufgetragen sein, die dann zwischen der oxidativ behandelten Zink/Nickel-Schicht und dem Trockenschmierstoff liegt. Als Konversionsschicht eignen sich organische oder anorganische Beschichtungsmittel wie z.B. Silicate oder Polymerwachse. Besonders geeignet ist das Produkt Aquares.The problem is solved by a coating system in which the dry lubricant is applied to a zinc / nickel layer that has previously been treated with an oxidizing agent. Alternatively, the dry lubricant can also be applied to a conversion layer, which then lies between the oxidatively treated zinc / nickel layer and the dry lubricant. Organic or inorganic coating agents such as e.g. Silicates or polymer waxes. The Aquares product is particularly suitable.
Mit dem erfindungsgemäßen Beschichtungssystem werden hervorragende, reproduzierbare Paarungseigenschaften mit unterschiedlichen Werkstoffen erreicht.Excellent, reproducible mating properties with different materials are achieved with the coating system according to the invention.
Ein besonderer Vorteil der Erfindung besteht darin, daß die Kombination einer oxidativ behandelten Zink/Nickel-Schicht mit einem Trockenschmierstoff eine hohe Haltbarkeit gegenüber physikalischen und chemischen Einflüssen besitzt und dabei dennoch gute Fließeigenschaften aufweist. Auch bei mehrfacher Demontage und erneuter Montage - selbst in der Größenordnung von 20 Wiederholungen - bleibt das Verhältnis von Anziehdrehmoment und Vorspannkraft bei Verbindungselementen die erfindungsgemäß beschichtet sind unverändert. Die erreichte Vorspannkraft bleibt auch bei der Verwendung unterschiedlicher Materialien bei fest- gelegtem Anziehdrehmoment in engen Grenzen. Insbesondere die Haft- und Abriebbeständigkeit des erfindungsgemäßen Systems sowie die Schlagbeständigkeit ist gegenüber dem Stande der Technik erheblich verbessert.A particular advantage of the invention is that the combination of an oxidatively treated zinc / nickel layer with a dry lubricant has a high durability against physical and chemical influences and still has good flow properties. Even with multiple disassembly and reassembly - even in of the order of 20 repetitions - the ratio of tightening torque and pretensioning force in the case of connecting elements which are coated according to the invention remains unchanged. The preload achieved remains within narrow limits even when using different materials with a specified tightening torque. In particular, the adhesion and abrasion resistance of the system according to the invention and the impact resistance have been considerably improved compared to the prior art.
Dies kann durch die Verwendung einer Konversionsschicht noch verstärkt werden. Hierbei wird als Trockenschmierstoff bevorzugt das anti-friction- coating Molykote D708 der Firma Molykote eingesetzt. Mit diesem System wird eine Temperaturbeständigkeit von -180 bis 200°C erreicht.This can be reinforced by using a conversion layer. The anti-friction coating Molykote D708 from Molykote is preferably used as the dry lubricant. A temperature resistance of -180 to 200 ° C is achieved with this system.
Mit Hilfe des Trockenschmierstoffs werden ferner die Unebenheiten im Gewinde der Bohrung ausgeglichen. Die optimierten Fließeigenschaften bewirken bei dem erfindungsgemäßen System ein Selbstversiegelung von Verletzungen der Außenhaut. Korrosionsbelastungen bei Fahrzeugen sind insbesondere im Fahrwerksbereich - dem Einsatzbereich von Radschrauben - erheblich. Mit dem erfindungsgemäßen System besteht selbst bei diesen außerordentlichen Belastungen ein hervorragender katholischer Korrosionsschutz sowie ein besonderer Widerstand gegen Kontaktkorrosion mit den unterschiedlichsten Werkstoffen (Leichtmetalllegierungen, insbesondere Aluminum- oder Magnesiumlegierungen oder Stahl). Dadurch ist auch unter erschwerten Einsatzbedingungen vermieden, daß eine Angriffsmöglichkeit für korrosive Stoffe oder sonstige die Beschichtung angreifende Chemikalien gegeben ist. Auch den besonderen chemischen Belastungen, wie sie beim Einsatz von aggressiven Reinigern beispielsweise zur Reinigung von Aluminiumfelgen eingesetzt werden hält das erfindungsgemäße System stand.With the help of the dry lubricant, the unevenness in the thread of the hole is also compensated. The optimized flow properties cause self-sealing of injuries to the outer skin in the system according to the invention. Corrosion loads on vehicles are particularly significant in the chassis area - the area of application of wheel bolts. With the system according to the invention, even with these extraordinary loads, there is excellent Catholic corrosion protection and a special resistance to contact corrosion with a wide variety of materials (light metal alloys, in particular aluminum or magnesium alloys or steel). This avoids, even under difficult operating conditions, the possibility of attack by corrosive substances or other chemicals attacking the coating. The system according to the invention also withstands the special chemical loads such as are used when using aggressive cleaners, for example for cleaning aluminum rims.
Ein besonderer Vorteil der Verwendung von oxidativ behandeltem Zink Nickel-Schwarz mit dem erfindungsgemäßen Beschichtungssystem besteht darin, daß die bei herkömmlichen Systemen erforderlich Schwarz- färbung entfällt, die die optische Kontrolle des Beschichtungssystems erleichtert und die Deckbeschichtungsgänge reduziert werden.A particular advantage of using oxidatively treated zinc nickel black with the coating system according to the invention is that the black materials required in conventional systems Coloring is eliminated, which makes it easier to visually inspect the coating system and reduces the number of top coats.
Die Färbung des beschichteten Gegenstandes mit Hilfe des erfindungsge- mäßen Beschichtungssystems bleibt auch nach längerem intensiven Gebrauch erhalten und weist kaum sichtbare Veränderungen auf, was insbesondere bei einem schwarzen Überzugssystem von Bedeutung ist.The coloring of the coated object with the aid of the coating system according to the invention is retained even after prolonged intensive use and shows hardly any visible changes, which is particularly important in the case of a black coating system.
Dies ist auch im Bereich der Beschichtung von Innenkonturen (vorzugsweise Vertiefungen oder Innen- Kraftangriffen) wie beispielsweise bei Schraubverbindungselementen von Bedeutung um den dekorativen und den Korrosionsschutzanforderungen zu genügen. Dies gilt bei Radschrauben vor allem für die Innenkontur des Schraubenkopfes.This is also important in the area of coating internal contours (preferably recesses or internal force attacks) such as, for example, with screw connection elements in order to meet the decorative and corrosion protection requirements. In the case of wheel bolts, this applies above all to the inner contour of the bolt head.
Der Trockenschmierstoff wird bevorzugt im Tauchschleuderverfahren abgeschieden und anschließend eingebrannt.The dry lubricant is preferably separated using the immersion centrifuge method and then burned in.
Durch eine kolloidale Rußbindung wird eine Kontakkorrosion vermieden. Colloidal soot binding prevents contact corrosion.
