Abstract
Description
Die Erfindung betrifft einen Schmierstoff, der Al2O3 enthält.The invention relates to a lubricant containing Al 2 O 3 .
Es
ist allgemein bekannt, dass eine mechanische Reibung von Bauteilen
untereinander zu Wärmeentwicklung und Energieverlust führt.
Auch bewirken die dabei auftretenden Reibungskräfte und
der Abrieb einen erhöhten Verschleiß. Zur Reibungsverminderung
ist ein Schmierstoff der Fa. MSH Mineralstoffhandel GmbH mit der
Bezeichnung „nanovit" bekannt, der einen Anteil von 99% Öl,
Fett oder Paste als Schmiermedium enthält. In einer diesbezüglichen
Pressemitteilung
Derartige Schmierstoffe lassen sich aus Gründen physikalischer Anforderungen nur in sehr begrenztem Maße im Vakuum einsetzen. Insbesondere in Vakuumbeschichtungsanlagen werden diese abgelehnt. Allerdings werden Vakuumbeschichtungsanlagen sehr häufig als Durchlaufbeschichtungsanlage mit zahlreichen mechanisch beweglichen Bauelementen konzipiert, die insbesondere der Substratbewegung innerhalb der Anlage dienen.such Lubricants can be removed for reasons of physical requirements use only to a very limited extent in a vacuum. Especially in vacuum coating plants these are rejected. Indeed Vacuum coating systems are very often used as a continuous coating machine designed with numerous mechanically moving components, in particular serve the substrate movement within the system.
Der Erfindung liegt somit die Aufgabe zugrunde, einen Schmierstoff anzugeben, der einerseits reibungsvermindernd wirkt und andererseits unter Vakuumbedingungen möglicherweise auch mit Wärmeeinwirkung einsetzbar ist.Of the Invention is therefore based on the object of specifying a lubricant on the one hand reduces friction and on the other hand under Vacuum conditions possibly also with heat can be used.
Gemäß der Erfindung wird dies dadurch gelöst, dass der Schmierstoff aus Al2O3 als Nanopulver mit einer Korngröße von 1 bis 400 nm und einem Trägermittel mit einem Anteil von 0 bis 50 Vol-% besteht. Dabei werden die Pulverteilchen die Reibungsverminderung bewirken. Das Trägermittel – sofern überhaupt vorhanden – dient der Unterstützung des Anhaftens des Nanopulvers an den zu schmierenden Gegenständen. Da dieses nur zu einem sehr geringen Anteil vorhanden ist, wird es keinen oder höchstens einen vernachlässigbaren Einfluss auf Vakuumprozesse, insbesondere Vakuumbeschichtungsprozesse aufweisen.According to the invention this is achieved in that the lubricant consists of Al 2 O 3 as nanopowder with a particle size of 1 to 400 nm and a carrier with a proportion of 0 to 50% by volume. The powder particles will cause the friction reduction. The carrier means - if present at all - serves to support the adhesion of the nanopowder to the objects to be lubricated. Since this is present only to a very small extent, it will have no or at most a negligible influence on vacuum processes, in particular vacuum coating processes.
In einer ersten ökonomischen und herstellungsgünstigen Variante ist vorgesehen, dass das Nanopulver aus einem mittels PVS-Verfahren (PVS = Physical Vapor Synthesis = physikalische Gasphasensynthese) hergestellten Al2O3-Nanopulver mit einer Korngröße von 300 bis 400 nm besteht.In a first economical and low-production variant, it is provided that the nanopowder consists of an Al 2 O 3 nanopowder having a particle size of from 300 to 400 nm, which is produced by means of PVS (Physical Vapor Synthesis = PVS).
Eine weitere kostengünstige Realisierung der Erfindung wird dadurch ermöglicht, dass das Nanopulver aus einem mittels CVR-Verfahren (CVR = Chemical Vapor Reaktion = chemische Gasphasenreaktion) hergestellten Al2O3-Nanopulver mit einer Korngröße von 1 bis 100 nm besteht.A further cost-effective implementation of the invention is made possible by the fact that the nanopowder consists of an Al 2 O 3 nanopowder having a grain size of 1 to 100 nm, produced by means of CVR (Chemical Vapor Reaction = Chemical Vapor Reaction).
Eine Verfahrensvariante sieht vor, dass das Trägermittel als ein aus dem Schmierstoff entweichendes temporäres Trägermittel ausgebildet ist. Somit wird beim Auftrag des Schmiermittels und beispielsweise zum Zwecke gleichmäßiger Verteilung das Trägermittel eingesetzt. Ist der Auftragevorgang been det, entweicht das Trägermittel wodurch jeder Einfluss auf den Prozess ausgeschlossen wird, da das Al2O3 von sich aus keinen Einfluss zeigt.A variant of the method provides that the carrier means is designed as a temporary carrier means escaping from the lubricant. Thus, the carrier is used in the application of the lubricant and, for example, for the purpose of uniform distribution. Once the application process has been completed, the carrier escapes, thereby excluding any influence on the process, since the Al 2 O 3 has no influence of its own accord.
Eine günstige Realisierung eines temporären Trägermittels ist darin zu sehen, dass das Trägermittel aus Ethanol C2H5OH oder C2H6O besteht.A favorable realization of a temporary carrier is to be seen in that the carrier agent consists of ethanol C 2 H 5 OH or C 2 H 6 O.
Für andere Einsatzgebiete, insbesondere dann, wenn geringe Einflüsse des Trägermittels in Kauf genommen werden können, kann es zweckmäßig sein, beispielsweise die haftverbessernden Eigenschaften des Trägermittel ständig ausnutzen zu können indem das Trägermittel als ein in dem Schmierstoff verbleibendes permanentes Trägermittel ausgebildet ist.For other uses, especially if minor influences the carrier can be accepted, It may be appropriate, for example, the adhesion-improving Constantly exploiting the properties of the vehicle to be able to by the carrier means as one in the Lubricant remaining permanent support means formed is.
In einer möglichen Realisierung eines permanenten Trägermittels besteht dieses aus n-Butan C4H10 und in einer anderen Realisierung aus Siliconöl oder synthetischem Polymer.In one possible implementation of a permanent carrier, this consists of n-butane C 4 H 10 and in another embodiment of silicone oil or synthetic polymer.
Infolge der geringen Korngröße bestehen zwischen den Partikeln des Nanopulvers und dem zu schmierenden Gegenstand solche Adhäsionskräfte, die eine gute Haftung des Nanopulvers gewährleisten, die in einigen Einsatzfällen vollkommen ausreichend ist. Hierfür ist vorgesehen, dass der Schmierstoff aus reinem Al2O3-Nanopulver mit einem Trägermittelanteil von 0% ausgebildet ist.Due to the small particle size, there are such adhesion forces between the particles of the nanopowder and the object to be lubricated that ensure good adhesion of the nanopowder is completely sufficient in some applications. For this purpose, it is provided that the lubricant is formed from pure Al 2 O 3 nanopowder with a carrier content of 0%.
Die Erfindung soll nachfolgend anhand mehrerer Ausführungsbeispiele näher erläutert werden. Dabei soll das erfindungsgemäße Schmiermittel nachfolgend mit seinen verschiedenen Realisierungen bei verschiedenen Einsatzzwecken beschrieben werden.The Invention will be described below with reference to several embodiments be explained in more detail.
