Abstract
Description
Die Erfindung betrifft ein Verfahren zur Vorkonditionierung einer zu beschichtenden Oberfläche.The The invention relates to a method for preconditioning a coating surface.
Bei der Herstellung von Verbrennungsmotoren wird aus Gründen der Energieeffizienz und der Emissionsreduzierung eine möglichst geringe Reibung und eine hohe Abrieb- und Verschleißfestigkeit angestrebt. Hierzu werden Motorbauteile, wie zum Beispiel Zylinderbohrungen bzw. deren Wandungen mit einer Laufflächenschicht versehen oder es werden Laufbuchsen in die Zylinderbohrungen eingesetzt, welche mit einer Laufflächenschicht versehen werden. Das Aufbringen solcher Laufflächenschichten erfolgt oft mittels thermischen Spritzens, beispielsweise Lichtbogendrahtspritzen. Beim Lichtbogendrahtspritzen wird zwischen zwei drahtförmigen Spritzwerkstoffen ein Lichtbogen durch Anlegen einer Spannung erzeugt. Dabei schmelzen die Drahtspitzen ab und werden beispielsweise mittels eines Zerstäubergases auf die zu beschichtende Oberfläche, beispielsweise die Zylinderwand befördert, wo sie sich anlagern.at The production of internal combustion engines is for reasons energy efficiency and emission reduction as much as possible low friction and high abrasion and wear resistance. For this purpose, engine components, such as cylinder bores or their walls provided with a tread layer or bushings are inserted into the cylinder bores, which are provided with a tread layer. The Application of such tread layers is often by means of thermal spraying, for example arc wire spraying. At the Arc wire spraying is between two wire-shaped spray materials generates an arc by applying a voltage. It will melt the wire tips and are for example by means of a nebulizer gas on the surface to be coated, for example the Cylinder wall transported where they attach.
Ziel ist dabei, die gesamte Lauffläche homogen zu beschichten. Um eine gute Haftung der Laufflächenschicht auf der zu beschichtenden Oberfläche, auch Substrat genannt, sicher zu stellen, sind verschiedene Verfahren zur Aktivierung der Oberfläche gebräuchlich, bei denen die Oberfläche angeraut wird, damit Beschichtungspartikel besser an der Oberfläche haften. Solche Verfahren sind beispielsweise Hochdruckwasserstrahlen (HDWS) oder Korundstrahlen. Diese Verfahren sind kompliziert in der Handhabung und bergen das Risiko, die Oberfläche mit unerwünschten Fremdstoffen zu kontaminieren. Beim Hochdruckwasserstrahlen können beispielsweise im Wasser vorhandene Bakterien in der aufgerauten Oberfläche siedeln.aim is going to coat the entire tread homogeneously. To ensure good adhesion of the tread layer on the coating surface, also called substrate, safe There are several methods for activating the surface common in which the surface is roughened, so that coating particles adhere better to the surface. Such methods are for example high-pressure water jets (HDWS) or corundum rays. These procedures are complicated to handle and harbor the risk of having unwanted surface Contaminate contaminants. When high-pressure water jetting can For example, bacteria present in the water in the roughened Settle surface.

Die Bearbeitung mittels des Laserstrahls erfordert eine sehr hohe Präzision.The Processing by means of the laser beam requires a very high precision.
Es ist daher eine Aufgabe der Erfindung, ein verbessertes Verfahren zur Vorkonditionierung einer zu beschichtenden Oberfläche anzugeben.It is therefore an object of the invention, an improved method for the preconditioning of a surface to be coated specify.
Die Aufgabe wird erfindungsgemäß gelöst durch ein Verfahren mit den Merkmalen des Anspruchs 1.The The object is achieved by a method having the features of claim 1.
Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.advantageous Further developments are the subject of the dependent claims.
Bei einem erfindungsgemäßen Verfahren zur Vorkonditionierung einer zu beschichtenden Oberfläche werden Hinterschnitte und/oder Vorformen der Hinterschnitte spanend und/oder prägend, beispielsweise mittels Drehen und/oder Fräsen und/oder einer Vorrichtung mit einer gehärteten Mikrotopographie auf einer der Bearbeitung dienenden Mantelfläche in die Oberfläche eingebracht.at a method according to the invention for preconditioning A surface to be coated becomes undercuts and / or preforming the undercuts by machining and / or embossing, for example by means of turning and / or milling and / or a device with a hardened microtopography a working surface serving in the surface brought in.
Beispielsweise kann eine Sägezahngeometrie in die Oberfläche gedreht oder gefräst werden, die einen Hinterschnitt umfasst.For example can create a sawtooth geometry in the surface be turned or milled, which includes an undercut.
Vorformen der Hinterschnitte können beispielsweise prismatische Strukturen sein, beispielsweise mit der Kontur eines zumindest annähernd gleichschenkligen Dreiecks. Diese Vorformen können dann in einem weiteren, spanlosen, das heißt nichtspanenden Verfahrensschritt so verformt werden, dass sich die gewünschten Hinterschnitte ergeben.preforms the undercuts, for example, prismatic structures be, for example, with the contour of an at least approximately isosceles Triangle. These preforms can then be used in another, non-cutting, that is non-chipping process step so be deformed, that the desired undercuts result.
Beispielsweise können Kanten solcher prismatischen Strukturen gespalten werden, so dass sich palmenblattförmige Hinterschnitte ergeben.For example can split edges of such prismatic structures be so that palm leaf-shaped undercuts result.
Alternativ können die Kanten der prismatischen Strukturen gestaucht werden, so dass sich t-förmige Hinterschnitte ergeben.alternative The edges of the prismatic structures can be upset so that there are T-shaped undercuts.
Ein Stauchen kann auch nach dem Spalten erfolgen um die Ausbildung der palmenblattförmigen Hinterschnitte zu verbessern.One Upsetting can also occur after splitting around the training of the to improve palm leaf-shaped undercuts.
Ebenso kann zunächst gestaucht werden um das Ergebnis anschließend durch Spalten zu optimieren.As well can first be upset to the result afterwards to optimize by columns.
Mittels der Vorrichtung, insbesondere einer axialsymmetrischen Vorrichtung mit mehreren Backen, mit einer gehärteten Mikrotopographie auf der zur Bearbeitung dienenden Mantelfläche können Vorformen in der Art von Mikrokavernen-Geometrien in die zu bearbeitende Oberfläche eingeprägt werden, indem die Vorrichtung auf die zu bearbeitende Oberfläche hin zugestellt wird. In mindestens einem weiteren Verfahrensschritt erfolgt ein spanloses Umformen der Mikrokavernengeometrie zur Bildung der Hinterschnitte.through the device, in particular an axisymmetric device with multiple jaws, with a hardened microtopography preforms can be used on the lateral surface for processing in the nature of microcavern geometries in the surface to be processed be imprinted by the device on the surface to be machined is delivered. In at least one further process step a non-cutting forming of Mikrokavernengeometrie carried out for education the undercuts.
In diesem Verfahrensschritt kann die Mikrokavernengeometrie beispielsweise gestaucht und/oder gespalten werden.In This process step, the microcavity geometry, for example compressed and / or split.
Die Mikrotopographie und ein radialer Freiheitsgrad der Vorrichtung können so beschaffen sein, dass sich eine Mikrokavernengeometrie mit etwa 100 μm tiefen Kavernen ergibt.The Microtopography and a radial degree of freedom of the device can be such that a Mikrokavernengeometrie with caverns of approximately 100 μm depth.
Mit auf solche Weise erzeugten Hinterschnitten ist eine optimale Adhäsion zwischen einer nachfolgend aufgebrachten Schicht und der Oberfläche erreichbar, da die Schicht sich in den Hinterschnitten verkrallt.With undercuts produced in this way is an optimal adhesion achievable between a subsequently applied layer and the surface, because the layer digs into the undercuts.
Alle Ausführungsformen des Verfahrens sind mit hoher Reproduzierbarkeit bei kurzen Taktzeiten wirtschaftlich in der Massenproduktion einsetzbar. Der Werkzeug- und Applikationsaufwand ist gering. Verglichen mit dem Hochdruckwasserstrahlverfahren ergibt sich eine verbesserte Umweltverträglichkeit, da kein verschmutztes Wasser entsorgt werden muss.All Embodiments of the method are with high reproducibility can be used economically in mass production at short cycle times. Of the Tool and application costs are low. Compared with that High-pressure water jet process results in improved environmental compatibility since no polluted water needs to be disposed of.
Die Vorkonditionierung mittels Spalten oder Stauchen der prismatischen Vorform führt zu besonders effektiven Hinterschnitten.The Preconditioning by splitting or upsetting the prismatic Preform leads to particularly effective undercuts.
Als Oberfläche kann insbesondere eine Innenfläche eines Hohlzylinders, beispielsweise eine Zylinderlaufbahn eines Verbrennungsmotors vorkonditioniert werden, wobei die Hinterschnitte im Hohlzylinder umlaufend erzeugt werden. Zum Drehen und/oder Fräsen und/oder Spalten und/oder Stauchen wir dabei insbesondere ein radial zustellbares Werkzeug verwendet um das Werkzeug zunächst problemlos ohne Beschädigung der Oberfläche in den Zylinder einzuführen und dann an Ort und Stelle Oberflächenbearbeitungsmittel des Werkzeugs im erforderlichen Ausmaß radial in Richtung der Oberfläche zuzustellen. Zum Entfernen des Werkzeugs aus dem Zylinder werden die Oberflächenbearbeitungsmittel wieder zurückgezogen. Zum Spalten kann ein axialsymmetrisches Werkzeug mit mindestens drei rotierbaren Walzen verwendet werden. Die Walzen sind vorzugsweise in der Art aufeinander gestapelter kreisförmiger Messer mit definiertem Abstand untereinander gebildet.When Surface can in particular an inner surface a hollow cylinder, for example a cylinder bore of a Combustion engine be preconditioned, the undercuts be generated circumferentially in the hollow cylinder. For turning and / or milling and / or columns and / or we compress in particular a radial deliverable tool initially used around the tool easily without damaging the surface in the cylinder introduce and then in place surface treatment agent the tool in the required extent radially in the direction deliver the surface. To remove the tool the cylinder becomes the surface treatment means again withdrawn. For splitting, an axisymmetric Tool be used with at least three rotatable rollers. The rollers are preferably stacked one on top of the other circular knife with a defined distance between each other educated.
