Vor teilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. In den Rahmen der Erfindung fallen sämtliche Kombinationen aus zumindest zwei von in der Beschreibung, den Ansprüchen und/oder den Figuren offenbarten Merkmalen.These The object is with regard to the protective layer arrangement with the feature of claim 1 and in terms of the component with the features of claim 9 solved. Before some developments of Invention are specified in the subclaims. In the Within the scope of the invention, all combinations are omitted at least two of in the description, the claims and / or features disclosed in the figures.
Der Erfindung liegt der Gedanke zugrunde, zusätzlich zu einer ersten Haftvermittlerschicht aus reinem Chrom oder zumindest mit einem Chromanteil eine zweite Haftvermittlerschicht vorzusehen, die einen Kohlenstoffanteil enthält. Durch diese Maßnahme kann die Haftfestigkeit der Verschleißschutzschichtanordnung auf einem zu beschichtenden Bauteil, insbesondere für ein Kraftstoff-Einspritzsystem, wesentlich verbessert werden. Bevorzugt ist die Schutzschicht mit tetragonal gebundenem, amorphem Kohlenstoff wasserstofffrei. Insbesondere kann eine verbesserte Temperaturbeständigkeit bei Prüftests unter einer inerten Gasatmosphäre bei einer Temperatur von etwa 400°C über einen Zeitraum von 150 Stunden erreicht werden.Of the Invention is based on the idea, in addition to a first primer layer of pure chromium or at least with to provide a second adhesion promoter layer to a chromium component, which contains a carbon content. By this measure may be the adhesive strength of the wear protection layer assembly on a component to be coated, in particular for a Fuel injection system, significantly improved. Prefers is the protective layer with tetragonal bonded, amorphous carbon hydrogen-free. In particular, an improved temperature resistance in test tests under an inert gas atmosphere at a temperature of about 400 ° C over a Period of 150 hours can be achieved.
In Weiterbildung der Erfindung ist mit Vorteil vorgesehen, dass die zweite Haftvermittlerschicht zusätzlich zu dem Kohlenstoffanteil einen Chromanteil aufweist. Anders ausgedrückt ist die zweite Haftvermittlerschicht bevorzugt als Mischschicht, umfassend Kohlenstoffanteile und Chromanteile, ausgeführt. Durch diese Maßnahme wird eine besonders haftfeste Schutzschichtanordnung erhalten.In Development of the invention is provided with advantage that the second adhesion promoter layer in addition to the carbon content has a chromium share. In other words, that is second adhesion promoter layer preferably as a mixed layer, comprising Carbon components and chromium components, executed. By This measure becomes a particularly adherent protective layer arrangement receive.
Von besonderem Vorteil ist eine Ausführungsform, bei der die zweite Haftvermittlerschicht als sogenannte Gradientenschicht mit an mindestens zwei Stellen unterschiedlichem Chrom-/Kohlenstoffverhältnis ausgebildet ist. Zur weiteren Verbesserung der Haftfestigkeit der Verschleißschutz schichtanordnung ist es dabei bevorzugt, wenn der Kohlenstoffanteil mit zunehmender Schichtdicke in Richtung Schutzschicht, bevorzugt linear, zunimmt.From particular advantage is an embodiment in which the second adhesion promoter layer as a so-called gradient layer with in at least two places different chromium / carbon ratio is trained. To further improve the adhesion of the Wear protection layer arrangement, it is preferred if the carbon content increases with increasing layer thickness in the direction of the protective layer, preferably linear, increases.
Von ganz besonderem Vorteil ist eine Ausführungsform der Verschleißschutzschichtanordnung, bei der die Schutzschicht aus tetragonal gebundenem, amorphem Kohlenstoff unmittelbar auf die zweite Haftvermittlerschicht aufgebracht ist. Besonders bevorzugt bildet die Schutzschicht dabei eine äußere Schicht der Verschleißschutzschichtanordnung, also eine Deckschicht, die in unmittelbarem Kontakt mit Betriebsmedien, beispielsweise Kraftstoff, gelangt.Of very particular advantage is an embodiment of the wear protection layer arrangement in which the protective layer of tetragonal bonded amorphous carbon is applied directly to the second adhesion promoter layer. Be In this case, the protective layer particularly preferably forms an outer layer of the wear protection layer arrangement, that is to say a cover layer which comes into direct contact with operating media, for example fuel.
Gute Ergebnisse im Hinblick auf eine optimierte Haftfestigkeit der Verschleißschutzschichtanordnung werden erreicht, wenn die erste Haftvermittlerschicht und/oder die zweite Haftvermittlerschicht eine Schichtdicke aus einem Wertebereich zwischen etwa 50 nm und etwa 300 nm aufweisen/aufweist. Besonders bevorzugt ist die Gesamtdicke der Verschleißschichtanordnung aus einem Wertebereich zwischen etwa 1 μm und 10 μm gewählt.Quality Results with regard to an optimized adhesive strength of the wear protection layer arrangement are achieved when the first primer layer and / or the second adhesion promoter layer a layer thickness of a range of values between about 50 nm and about 300 nm. Especially preferred is the total thickness of the wear layer arrangement from a value range between about 1 .mu.m and 10 .mu.m selected.
Besonders bevorzugt ist es, die erste Haftvermittlerschicht mittels eines PVD-Verfahrens (physikalische Gasphasenabscheidung) unmittelbar auf die Oberfläche des zu beschichtenden, vorzugsweise zumindest im zu beschichtenden Bereich aus Stahl bestehenden, ersten Bauteils aufzubringen. Mit Vorteil wird hierzu ein Chrom-Target gesputtert, in dem dieses mit inerten Argonionen beschossen wird. Idealerweise wird auch die Schutzschicht mittels eines PVD-Verfahrens, vorzugsweise unter Vakuum, ganz bevorzugt durch Lichtbogenverdampfen (Arc-PVD) aufgebracht. Für den Fall, dass die zweite Haftvermittlerschicht als Mischschicht umfassend o der bestehend aus Chrom und Kohlenstoff ausgebildet wird, ist es bevorzugt, diese zweite Haftvermittlerschicht durch ein kombiniertes PVD/CVD-Verfahren (CVD = chemische Gasphasenabscheidung) aufzubringen, wobei das Chrom-Target weiterhin durch Ionenbeschuß zerstäubt und damit in die Gasphase überführt wird und zusätzlich Acetylengas (Ethin) eingeleitet wird, was zur Aufkonzentration von Kohlenstoff in der zweiten Haftvermittlerschicht führt. Durch eine geeignete Prozessführung kann der Anteil an Kohlenstoff mit zunehmender Schichtdicke erhöht werden.Especially it is preferred that the first adhesion promoter layer by means of a PVD process (physical vapor deposition) immediately on the surface of the to be coated, preferably at least in the area to be coated made of steel, first Apply component. Advantageously, this is a chrome target sputtered by bombarding it with inert argon ions. Ideally also the protective layer by means of a PVD process, preferably under vacuum, most preferably by arc vapor deposition (Arc-PVD) applied. In the event that the second adhesive layer as a mixed layer comprising o consisting of chromium and carbon is formed, it is preferred, this second adhesive layer by a combined PVD / CVD process (CVD = Chemical Vapor Deposition) with the chromium target further atomized by ion bombardment and thus transferred to the gas phase and in addition Acetylene gas (ethyne) is introduced, resulting in the concentration of Carbon in the second adhesion promoter layer leads. Through a suitable process control, the proportion of carbon be increased with increasing layer thickness.
