Abstract

A surface of a non-metal workpiece is treated by dispersing grain size particles (2) of metal or non-metal into the outer layer of the workpiece during its prodn. and exposing part of the particles at the surface by grinding or blasting. USE/ADVANTAGE - The particles are used as an intermediate layer and contact layer for a metallic or non-metallic coating (4) or can act directly to improve some surface property such as lubrication, wear resistance etc. Esp. useful for coating fibre-reinforced plastics. Improves the adhesion of the coating layer or avoids the need for a final coating.

Description

Gegenstand der Anmeldung ist die Behandlung von Oberflächen nichtmetallischer Werkstoffe, insbesondere von Gegenständen aus keramischen oder faserverstärkten Kunsstoffen.The subject of the application is the treatment of surfaces of non-metallic materials, especially objects made of ceramic or fiber-reinforced plastics.

Zur Erhöhung bestimmter Wirkungen der Oberflächen von Gegenständen aus nichtmetallischen Werkstoffen wie Widerstand gegen Verschleiß, Verbesserung der Schmiereigenschaften und dgl. werden metallische, keramische oder polymere Schichten auf den Gegenstand aufgebracht. Das Auftragen dieser Schichten erfolgt dabei in der Regel durch thermisches Spritzen, galvanische oder physikalische Abscheidung aus der Dampfphase (PVD) oder mit Hilfe eines anderen geeigneten Verfahrens. Es zeigte sich, daß derart aufgebrachte Schichten oft keine ausreichende Haftung zum Grundkörper aufweisen, so daß es zu Abplatzungen der Beschichtung kommt. Dadurch wird der gewünschte Effekt stark vermindert, wenn nicht aufgehoben.To increase certain effects of the surfaces of objects made of non-metallic Materials such as resistance to wear, improvement of the lubricating properties and the like metallic, ceramic or polymeric layers are applied to the object. The These layers are usually applied by thermal spraying, galvanic or physical vapor deposition (PVD) or with the help of another appropriate procedure. It was found that layers applied in this way are often insufficient Have adhesion to the base body, so that the coating flakes off. This greatly reduces, if not eliminates, the desired effect.

Zur Behebung dieses Mangels wurden Gegenstände mit Zwischenschichten versehen, die einerseits gut auf dem Gegenstand haften und andererseits eine feste Bindung mit dem Werkstoff der Beschichtung eingehen. Aus der Technik der Beschichtung metallischer Werkstoffe ist bekannt, in solchen Fällen Zwischenschichten aufzutragen, die in den Werkstoff des zu beschichtenden Gegenstandes eindiffundieren. Eine solche Verfahrensweise schließt sich aber bei Gegenständen aus nichtmetallischen Werkstoffen aus. Aus der DE-OS 30 21 621 ist ein "Verfahren zur Herstellung von nichtmetallischen Formstücken mit metallischer Deckschicht" bekannt, das durch zwei aufeinanderfolgende Maßnahmen gekennzeichnet ist, nämlich zunächst die metallische Deckschicht im Sprühverfahren auf die Innenwandung einer Form aufzubringen und danach das nichtmetallische Material im Spritzgießverfahren einzubringen. Eine solche Vorgehensweise ist aber bei Gegenständen, z. B. aus faserverstärkten Kunststoffen nicht anwendbar, da die Herstellungstechnik hier eine ganz andere ist als die der genannten DE-OS zugrundeliegende Verfahrensweise.To remedy this defect, objects were provided with intermediate layers, on the one hand adhere well to the object and on the other hand a firm bond with the material of the Apply coating. It is known from the technology of coating metallic materials that in such cases, apply intermediate layers that are in the material of the coating Diffuse the object. However, such a procedure is included Objects made of non-metallic materials. From DE-OS 30 21 621 is a "Process for the production of non-metallic fittings with a metallic cover layer" known, which is characterized by two successive measures, namely initially apply the metallic cover layer to the inner wall of a mold by spraying and then insert the non-metallic material by injection molding. Such The procedure is for objects such. B. not made of fiber-reinforced plastics applicable, since the manufacturing technology is very different from that of the mentioned DE-OS underlying procedure.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren zur Verbesserung der Eigenschaften der Oberflächen von nichtmetallischen Grundkörpern zu schaffen, das auf die besondere Herstellungstechnik und Zusammensetzung von Gegenständen aus nichtmetallischen, keramischen oder Werkstoffen aus Polymeren anwendbar ist, insbesondere aber auf solche, die aus faserverstärkten Kunststoffen erstellt wurde. Die Aufgabe wurde dadurch gelöst, daß in die Außenschicht des nichtmetallischen Gegenstandes Partikel aus Metall, Keramik oder einem Polymer eingelagert werden, die vom nichtmetallischen Werkstoff umschlossen und durch eine abtragende Behandlung freigelegt werden. In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, daß die Oberflächenschicht angeschliffen oder gestrahlt wird. Die Erfindung sieht ferner vor, daß die freigelegten Teile der Partikel entweder für sich schon den erwünschten Effekt bringen oder aber eine feste Bindung mit dem Werkstoff einer Beschichtung eingehen.The invention is therefore based on the object of a method for improving the To create properties of the surfaces of non-metallic base bodies that on the special manufacturing technique and composition of objects non-metallic, ceramic or materials made of polymers is applicable, in particular  but on those made from fiber-reinforced plastics. The task was solved in that in the outer layer of the non-metallic object particles Metal, ceramics or a polymer are embedded by the non-metallic material enclosed and exposed by ablative treatment. In another Embodiment of the invention it is proposed that the surface layer be ground or is blasted. The invention further provides that the exposed parts of the particles either for bring the desired effect or a firm bond with the material a coating.

Die Abbildung zeigt einen Vertikalschnitt durch einen gemäß der Erfindung beschichteten Gegenstand als Beispiel einer Anwendung.The figure shows a vertical section through a coated according to the invention Item as an example of an application.

Der Gegenstand (1) besteht aus einem faserverstärkten Kunststoff und ist z. B. durch Laminieren von Hand oder Wickeln hergestellt. Die einzelnen Laminate sind schichtweise aufgetragen und schichtweise mit einem Kunstharz getränkt. Ähnlich erfolgt das Wickeln, bei dem die Fasern mit Kunststoff getränkt werden und dann lagenweise auf einen Dorn aufgebracht und zum Gegenstand der gewünschten Form und Größe gewickelt werden. Die Gegenstände können auch durch einen Formpreßvorgang hergestellt sein.The object ( 1 ) consists of a fiber-reinforced plastic and is, for. B. made by hand laminating or winding. The individual laminates are applied in layers and impregnated in layers with a synthetic resin. The winding is similar, in which the fibers are impregnated with plastic and then applied in layers to a mandrel and wound into the desired shape and size. The articles can also be made by a compression molding process.

Erst gegen Ende des Laminier- bzw. Wickelvorganges wird dem Kunststoff ein Medium zugegeben, das körnige Struktur (2) hat und metallisch oder nichtmetallisch sein kann. Die Körner werden vom Kunststoff umschlossen (3) und stören im nicht überarbeiteten Zustand nicht das Oberflächenaussehen, sie sind inaktiv. Soll der Gegenstand z. B. mit einem metallischen Medium beschichtet werden oder bestimmte Eigenschaften der Oberfläche nutzbar gemacht werden, wird die Oberfläche (4) des Gegenstandes angeschliffen oder gestrahlt. Dadurch werden die Körner partiell freigelegt und aktiviert und können beispielsweise aus der Dampfphase abgeschiedenem Metall oder Beschichtungen anderer Art als Kontaktfläche dienen. Die auf der Oberfläche des Gegenstandes aufgebrachte Deckschicht (4) wird fest auf dem Gegenstand verankert.Only towards the end of the lamination or winding process is a medium added to the plastic, which has a granular structure ( 2 ) and can be metallic or non-metallic. The grains are enclosed by the plastic ( 3 ) and do not disturb the surface appearance when not revised, they are inactive. If the object z. B. coated with a metallic medium or certain properties of the surface are made usable, the surface ( 4 ) of the object is ground or blasted. As a result, the grains are partially exposed and activated and, for example, metal or coatings of other types deposited from the vapor phase can serve as a contact surface. The covering layer ( 4 ) applied to the surface of the object is firmly anchored to the object.

Sollen nichtmetallische Deckschichten auf dem Gegenstand angeordnet werden, wird das körnige Medium auf den Werkstoff der Deckschicht abgestimmt. So wird einer Teflonbeschichtung vorteilhafterweise ein körniges Teflongemisch in der Oberfläche zugeordnet. Es zeigte sich jedoch, daß zur Erzielung bestimmter Effekte, zum Beispiel einer verbesserten Schmierwirkung, bereits das in die Oberfläche eingebrachte und dann freigelegte körnige Medium ausreicht, den gewünschten Effekt zu erzielen. Auf eine zusätzliche Deckschicht kann dann verzichtet werden.If non-metallic cover layers are to be arranged on the object, this will be granular medium matched to the material of the top layer. That's how one becomes Teflon coating advantageously assigned a granular Teflon mixture in the surface. However, it was found that in order to achieve certain effects, for example an improved one Lubricating effect, already the grainy introduced into the surface and then exposed Medium is sufficient to achieve the desired effect. Can on an additional top layer then be dispensed with.
