Die Erfindung betrifft ein Verfahren zur Beschichtung eines thermisch und tribologisch hoch beanspruchten Bauteils einer Brennkraftmaschine mit einer DLC-Schicht, das dadurch gekennzeichnet ist, dass zunächst auf das Bauteil mittels plasmaunterstützter, chemischer Gasphasenabscheidung eine erste DLC-Schicht aufgebracht wird und danach eine weitere SLC-Schicht aufgebracht wird, die gegenüber der ersten DLC-Schicht steifer und härter ist.The invention relates to a method for coating a thermally and tribologically highly stressed component of an internal combustion engine with a DLC layer, which is characterized in that first a first DLC layer is applied to the component by means of plasma-assisted, chemical vapor deposition and then a further SLC Layer is applied, which is stiffer and harder compared to the first DLC layer.

Description

Die Erfindung betrifft ein Verfahren zur Beschichtung eines thermisch und tribologisch hoch beanspruchten Bauteiles einer Brennkraftmaschine mit einer DLC-Schicht, gemäß den Merkmalen des Oberbegriffes des Patentanspruches 1.The The invention relates to a method for coating a thermal and tribologically highly stressed components of an internal combustion engine with a DLC layer, according to the characteristics the preamble of claim 1.

Es ist bekannt, thermisch und tribologisch hoch beanspruchte Bauteile einer Brennkraftmaschine, wie Bolzen, Kobenringe, Pleuellager, Zylinderlaufflächen des Kolbens und dergleichen so zu gestalten, dass Reibung, Verschleiß und Adhäsionsneigung vermieden werden.It is known, thermally and tribologically highly stressed components an internal combustion engine, such as bolts, Kobenringe, connecting rod bearings, cylinder surfaces of the Pistons and the like so that friction, wear and adhesion tendency be avoided.

Hierzu kommen beispielsweise eloxierte Nuten, Buchsen aus Kupferwerkstoffen und dergleichen in Betracht. Hierbei handelt es sich zusätzlich zu dem eigentlichen Bauteil um weitere Bauteile, die extra gefertigt und montiert werden müssen, was von Nachteil ist.For this For example, come anodized grooves, sockets made of copper materials and the like. This is in addition to the actual component to additional components that are made extra and have to be mounted which is disadvantageous.

Darüber hinaus ist es bekannt, thermisch und tribologisch hoch beanspruchte Bauteile mit einer DLC-Schicht mit einer zusätzlichen Haftvermittlerschicht auf das Bauteil aufzubringen. Hierbei bedeutet in an sich bekannter Weise die Abkürzung „DLC” „Diamond Like Carbon”. Als Haftvermittlerschicht kommt z. B. Chrom oder Titan und/oder CrN, TiN in Betracht, damit die DLC-Schicht in erforderlichem Maße auf der Oberfläche des Bauteils haftet. Diese Haftvermittler bedingen aber einen zusätzlichen Arbeitsschritt und zusätzliche Einrichtungen in der Beschichtungsanlage, was zu hohen Zusatzkosten führt.Furthermore It is known, thermally and tribologically highly stressed components with a DLC layer with an additional primer layer to apply to the component. This means in known per se Way the abbreviation "DLC" "Diamond Like Carbon ". As a primer layer z. As chromium or titanium and / or CrN, TiN, so that the DLC layer to the extent necessary on the surface of the component adheres. However, these adhesion promoters require an additional Work step and additional Facilities in the coating plant, resulting in high additional costs leads.

Der Erfindung liegt daher die Aufgabe zu Grunde, ein verbessertes Verfahren zur Beschichtung eines thermisch und tribologisch hoch beanspruchten Bauteiles einer Brennkraftmaschine mit einer DLC-Schicht anzugeben.Of the The invention is therefore based on the object, an improved method for coating a thermally and tribologically highly stressed Specify components of an internal combustion engine with a DLC layer.

Diese Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst.These The object is solved by the features of claim 1.

Erfindungsgemäß ist vorgesehen, dass zunächst auf das Bauteil mittels plasmaunterstützter chemischer Gasphasenabscheidung eine erste DLC-Schicht aufgebracht wird und danach eine weitere DLC-Schicht aufgebracht wird, die gegenüber der ersten DLC-Schicht eine verringerte Steifigkeit, Härte und geringere Eigenspannungen aufweist.According to the invention, it is provided that first on the component by means of plasma-assisted chemical vapor deposition a first DLC layer is applied and then another DLC layer is applied, which faces the first DLC layer a reduced stiffness, hardness and lower residual stresses.

Dies hat zunächst den Vorteil, dass die Beschichtung ohne eine Haftvermittlerschicht erfolgen kann, so dass das Verfahren hinsichtlich der Witschaftlichkeit verbessert ist, da die Verwendung einer Haftvermittlerschicht entfällt.This has first the advantage that the coating without a primer layer can be done so that the process in terms of literacy is improved, since the use of a primer layer is eliminated.

Darüber hinaus hat das Verfahren den Vorteil, dass auf das Bauteil in einem einzigen Prozeß (Verfahrensschritt) zunächst eine erste DLC-Haftschicht mit einem auf das Eisen-Basis-Bauteil angepasstem E-Modul im PA-CVD-Verfahren (plasmaunterstützte chemische Gasphasenabscheidung) aufgebracht wird, wodurch bei mechanischer Belastung der so beschichteten Oberfläche geringere Spannungen in der Schicht-Substrat-Grenzfläche entstehen. Die mittels des PA-CVD-Verfahrens auf die Oberfläche des Bauteils abgeschiedene zweite DLC-Funktionsschicht hat eine sehr hohe Härte und kann daher mit dem Laufpartner (z. B. tragender Kolbenschaftwandabschnitt mit dem Laufpartner Zylinderlauffläche) nicht einlaufen, so dass über die Laufzeit ein vergleichbar hoher Verschleiß auftreten würde. Außerdem würde eine derartige Schicht zu Ausbrüchen neigen, die dann zum Schichtversagen führen würde. Um dies zu vermeiden, ist weiterhin erfindungsgemäß vorgesehen, dass auf diese erste, harte Schicht, eine weitere, weichere DLC-Einlaufschicht abgeschieden wird. Auch dies kann wieder im PA-CVD-Verfahren erfolgen.Furthermore the process has the advantage of being on the component in a single Process (process step) first a first DLC adhesive layer with one on the iron base component adapted modulus of elasticity in the PA-CVD method (plasma-enhanced chemical Gas phase separation) is applied, whereby in mechanical Load the surface so coated lower stresses in the layer-substrate interface arise. The deposited by means of the PA-CVD method on the surface of the component second DLC functional layer has a very high hardness and can therefore with the Running partner (eg supporting piston skirt wall section with the running partner Cylinder surface) do not run in, so over the running time a comparably high wear would occur. Besides, one would such layer tend to eruptions, which then lead to shift failure would. Around To avoid this, is further provided according to the invention that on this first hard layer, another softer DLC inlet layer is deposited. Again, this can be done in the PA-CVD method.

Dabei ist es erfindungsgemäß vorgesehen, dass beim Abscheiden der weiteren Schichten auf die erste aufgebrachte Schicht der Übergang entweder in Stufen erfolgt, wodurch eine so genannte Multi-Layer-Schicht entsteht, oder kontinuierlich erfolgt, wodurch man eine so genannte Gradienten-Schicht erhält. Der genannte Beschichtungsprozess zeichnet sich durch eine sehr hohe Abscheiderate und geringe Substrattemperaturen aus, wodurch das erfindungsgemäße Verfahren hinsichtlich Herstellungskosten und Herstellungszeit bei der Beschichtung der Bauteile sehr günstig ist.there It is inventively provided that when depositing the further layers on the first applied Layer the transition either done in stages, creating a so-called multi-layer layer arises, or occurs continuously, creating a so-called Gradient layer receives. The mentioned coating process is characterized by a very high deposition rate and low substrate temperatures, which the inventive method in terms of manufacturing costs and production time in the coating the components very cheap is.

Damit bietet das thermisch und tribologisch hoch beanspruchte Bauteil, das mittels des erfindungsgemäßen Verfahrens beschichtet worden ist, eine gesteigerte Verringerung von Reibung und Verschleiß während seines Betriebes, wodurch weiterhin in besonders vorteilhafter Weise Kaltverschweißungen, wie insbesondere Plattieren und Micro-Welding, vermieden werden. Weiterhin zeichnet sich das erfindungsgemäße Verfahren durch geringere Kosten und Umweltfreundlichkeit bei gleichzeitig höherer tribologischer Leistungsfähigkeit des Bauteiles aus.In order to offers the thermally and tribologically highly stressed component, that by means of the method according to the invention has been coated, an increased reduction of friction and wear during his Operation, which further in a particularly advantageous manner cold welding, as in particular plating and micro-welding, be avoided. Furthermore, the inventive method is characterized by lower Cost and environmental friendliness with higher tribological capacity of the component.

Bei den thermisch und tribologisch hoch beanspruchten Bauteilen handelt es sich um Bauteile einer Brennkraftmaschine wie z. B. Kolben, Pleuel, Bolzen, Kolbenringe, Gleitlager und dergleichen.at is the thermally and tribologically highly stressed components it is components of an internal combustion engine such. Piston, connecting rods, bolts, Piston rings, plain bearings and the like.

Unter der Bezeichnung DLC (Beschichtung aus diamatähnlichem Kohlenstoff) sind vorzugsweise alle in der VDI 2840 in Gruppe 2 aufgeführten Schichten zu verstehen. DLC-Schichten bestehen im Wesentlichen aus Kohlenstoff, der in sp2 und/oder sp3 Bindungen gebunden ist, wobei der Bindungscharakter die Eigenschaften der Schicht wesentlich bestimmt. Als besonders vorteilhaft hat sich eine amorphe wasserstoffhaltige metallfreie DLC-Schicht (a-C:H) erwiesen, bei der beide Bindungsarten im Verhältnis 60–80:20–40 vorhanden sind.The term DLC (coating of diamond-like carbon) is to be understood as meaning preferably all layers listed in VDI 2840 in group 2. DLC layers consist essentially of carbon, which is bound in sp2 and / or sp3 bonds, wherein the binding character essentially the properties of the layer Right. Particularly advantageous is an amorphous hydrogen-containing metal-free DLC layer (aC: H) has been found, in which both types of bonding in the ratio 60-80: 20-40 are present.

Die einzige Figur zeigt schematisch ein Bauteil, welches nach dem erfindungsgemäßen Verfahren hergestellt worden ist und einen dementsprechenden Schichtaufbau aufweist.The single figure shows schematically a component which by the method according to the invention has been prepared and a corresponding layer structure having.
