Die vorliegende Erfindung betrifft ein Bauteil, welches Luft- oder Gasströmungen ausgesetzt und überwiegend aus einem Kunststoffmaterial gebildet ist, so dass das Kunststoffmaterial zumindest zum Teil im Bereich der der Strömung ausgesetzten Oberfläche des Bauteils vorliegt, wobei das Kunststoffmaterial einen Erosionsschutz an der Oberfläche aufweist. Außerdem betrifft die vorliegende Erfindung ein Verfahren zur Herstellung eines entsprechenden Bauteils mit Erosionsschutzschicht.The present invention relates to a component which is exposed to air or gas flows and formed predominantly of a plastic material, so that the plastic material is present at least partially in the region of the flow-exposed surface of the component, wherein the plastic material has erosion protection on the surface. Moreover, the present invention relates to a method for producing a corresponding component with erosion protection layer.
Erosionsschutzsysteme sind für strömungsbelastete Bauteile insbesondere in der Luftfahrtindustrie seit langem bekannt.Erosion control systems have long been known for flow-loaded components, especially in the aerospace industry.
So werden für metallische Turbinenbauteile in der
Neben diesen komplexen und aufwändigen Schichtsystemen für hochbelastete metallische Bauteile aus komplexen Metalllegierungen sind für Kunststoffbauteile in der Flugzeugindustrie, wie beispielsweise Rotorblätter von Hubschrauberotoren, Eintrittskanten von Propellerblättern bei Propellermaschinen und dergleichen einfache Erosionsschutzmaßnahmen bekannt. So werden an erosionsbelasteten Bereichen der Kunststoffbauteile entsprechende metallische Erosionsschutzteile in Form von metallischen Verkleidungen, wie aufgeklebte Metallfolien, Metallgewebe oder Metallfilze, oder integrierte Metallkanten vorgesehen. Aus der
Derartige erosionsgeschützte Kunststoffbauteile zeigen jedoch insbesondere über die langen Lebensdauern der Kunststoffbauteile einen ungenügenden Erosionsschutz.However, such erosion-protected plastic components show inadequate erosion protection, in particular over the long lifetimes of the plastic components.
Es ist deshalb Aufgabe der vorliegenden Erfindung, ein Kunststoffbauteil sowie ein entsprechendes Verfahren zur Herstellung bereitzustellen, welches die Probleme des Standes der Technik löst, also insbesondere einen zuverlässigen und dauerhaften Erosionsschutz für das Kunststoffbauteil bereitstellt, wobei gleichzeitig das Bauteil wirtschaftlich sinnvoll und somit effektiv herstellbar ist.It is therefore an object of the present invention to provide a plastic component and a corresponding method for the production, which solves the problems of the prior art, so in particular provides a reliable and durable erosion protection for the plastic component, at the same time the component is economically reasonable and thus effectively produced ,
Diese Aufgabe wird gelöst durch ein Bauteil mit den Merkmalen des Anspruchs 1 sowie ein Verfahren zur Herstellung eines entsprechenden Bauteils mit den Merkmalen des Anspruchs 14. Vorteilhafte Ausgestaltungen sind Gegenstand der abhängigen Ansprüche.This object is achieved by a component with the features of
Die Erfindung geht aus von der Erkenntnis, dass ein effektiver Erosionsschutz mittels eines Mehrlagenschichtsystems erzielbar ist, wie es bereits für komplexe metallische Legierungen in hochbeanspruchten Metallbauteilen von Gasturbinen eingesetzt wird. Die Kombination von harten und weichen Schichten, die insbesondere durch Dampfphasenabscheidung innig und fest miteinander verbunden sind, bietet beim Auftreffen von Partikeln, Flüssigkeiten und Gasströmungen die für die Erosionsschutzwirkung bedeutsame Kombination aus Nachgiebigkeit und Härte. Insbesondere durch dünne Teilschichten des Mehrlagenschichtsystems, wie sie durch Dampfphasenabscheidung erzeugt werden können, im Bereich von einigen nm Schichtdicke, wie beispielsweise 10 nm bis zu einigen µm Dicke, beispielsweise bis zu 10 µm Dicke, insbesondere im Bereich von 100 nm bis 0,5 µm Schichtdicke, vorzugsweise 200 nm bis 400 nm Dicke können hervorragende Erosionsbeständigkeitseigenschaften erzielt werden. Vergleichbare Ergebnisse lassen sich auch nicht durch eine aufgeklebte Metallfolie mit einer darauf angeordneten Metall-Keramik-Mischschicht, wie in der
Zur Abscheidung der Schichten können Dampfphasenabscheideprozesse, insbesondere physikalische Dampfphasenabscheideverfahren und vorzugsweise gepulstes Kathodenzerstäuben (Sputtern) eingesetzte werden.For depositing the layers, vapor phase deposition processes, in particular physical vapor phase deposition processes and preferably pulsed sputtering, can be used.
Bei der Aufbringung des Mehrlagenschichtsystems auf einer Metallverkleidung bzw. einer Metallverstärkung, also einem Metallformteil, einer Metallfolie oder dergleichen, wie insbesondere Metallgewebe, -filz usw., kann das Mehrlagenschichtsystem vor Anordnung der Metallverkleidung bzw. Metallverstärkung auf dem Kunststoffbauteil oder nach der Aufbringung auf dem Kunststoffbauteil abgeschieden werden.When applying the multi-layer system on a metal panel or a metal reinforcement, so a metal mold, a metal foil or the like, in particular metal fabric, felt, etc., the multilayer system before placing the metal panel or metal reinforcement on the plastic component or after application to the Plastic component to be deposited.
Sofern das Mehrlagenschichtsystem vor Anbringung der Metallverkleidung bzw. Metallverstärkung auf dem Kunststoffbauteil abgeschieden wird, können sämtliche geeigneten Kunststoffe, insbesondere partikelverstärkte oder phasenverstärkte Kunststoffe für das Kunststoffbauteil Verwendung finden.If the multi-layer system is deposited on the plastic component before attachment of the metal cladding or metal reinforcement, all suitable plastics, in particular particle-reinforced or phase-reinforced plastics, can be used for the plastic component.
Wird jedoch das Mehrlagenschichtsystem in Anwesenheit des Kunststoffbauteils abgeschieden, so muss ein vakuumbeständiger und/oder hochtemperaturbeständiger Kunststoff gewählt werden, der die nötigen Temperaturen und/oder Druckverhältnisse beim Abscheideprozess für das Mehrlagenschichtsystem überstehen kann. Für den Abscheideprozess können insbesondere auch Niedertemperaturabscheideverfahren mit Prozesstemperaturen im Bereich von kleiner oder gleich 300°C, insbesondere kleiner oder gleich 200 °C eingesetzt werden. Als vakuumbeständige und/oder temperaturbeständige Kunststoffe, die für Dampfphasenbeschichtungen geeignet sind, bieten sich insbesondere Polyetherketone, Polyetheretherketone und dergleichen an.However, if the multi-layer system is deposited in the presence of the plastic component, then a vacuum-resistant and / or high-temperature-resistant plastic must be selected, which can withstand the necessary temperatures and / or pressure conditions during the deposition process for the multilayer system. In particular, low-temperature deposition processes with process temperatures in the range of less than or equal to 300 ° C., in particular less than or equal to 200 ° C., can also be used for the deposition process. As vacuum-resistant and / or temperature-resistant plastics which are suitable for vapor-phase coatings, polyether ketones, polyether ether ketones and the like are particularly suitable.
Vor dem Aufbringen des Mehrlagenschichtsystems kann die zu beschichtende Oberfläche entsprechend vorbereitet werden, um beispielsweise die Haftfestigkeit zu verbessern. Hierzu können bekannte nasschemische Ätzverfahren und/oder Plasmabehandlungsverfahren eingesetzt werden. Insbesondere bei der Abscheidung des Mehrlagenschichtsystems direkt auf dem Kunststoff kann sich eine entsprechende Vorbehandlung anbieten.Before applying the multi-layer system, the surface to be coated can be prepared accordingly, for example, to improve the adhesion. For this purpose, known wet-chemical etching processes and / or plasma treatment processes can be used. In particular, in the deposition of the multi-layer system directly on the plastic may offer a corresponding pre-treatment.
