Abstract
Description
Die Erfindung betrifft ein Bauteil nach den Merkmalen des Oberbegriffs des Anspruchs 1, ein Verfahren zur Herstellung eines Bauteils nach den Merkmalen des Oberbegriffs des Anspruchs 6.The invention relates to a component according to the features of the preamble of
Aus dem Stand der Technik sind beschichtete Bauteile allgemein bekannt, beispielsweise Bremsscheiben für Fahrzeuge. Derartige Bremsscheiben weisen ein Substrat auf, welches einen Grundkörper der Bremsscheibe bildet und mit einer Deckschicht beschichtet ist, die einen Reibkörper der Bremsscheibe bildet.Coated components are generally known from the prior art, for example brake disks for vehicles. Such brake discs have a substrate which forms a base body of the brake disc and is coated with a cover layer which forms a friction body of the brake disc.
Der Erfindung liegt die Aufgabe zu Grunde, ein verbessertes Bauteil und ein verbessertes Verfahren zur Herstellung eines Bauteils anzugeben.The invention is based on the object to provide an improved component and an improved method for producing a component.
Die Aufgabe wird erfindungsgemäß gelöst durch ein Bauteil mit den Merkmalen des Anspruchs 1 und ein Verfahren zur Herstellung eines Bauteils mit den Merkmalen des Anspruchs 6.The object is achieved by a component having the features of
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Ein Bauteil umfasst ein Substrat und zumindest eine Deckschicht. Erfindungsgemäß ist zwischen dem Substrat und der zumindest einen Deckschicht zumindest eine Zwischenschicht ausgebildet.A component comprises a substrate and at least one cover layer. According to the invention, at least one intermediate layer is formed between the substrate and the at least one cover layer.
Durch die Zwischenschicht sind Haftungseigenschaften des Bauteils verbessert und es ist insbesondere eine Delamination der Schichten des Bauteils verhindert oder zumindest deutlich reduziert. Derartige Delaminationen können bei Bauteilen nach dem Stand der Technik beispielsweise auftreten durch Korrosion, unterschiedliche Wärmeausdehnungskoeffizienten, Ausbreitung von Rissen in der Deckschicht bis zum Substrat und durch unterschiedliche elektrochemische Spannungspotentiale zwischen der Deckschicht und dem Substrat.Adhesive properties of the component are improved by the intermediate layer and in particular delamination of the layers of the component is prevented or at least significantly reduced. Such delaminations can occur in the case of components according to the prior art, for example due to corrosion, different coefficients of thermal expansion, propagation of cracks in the cover layer to the substrate and by different electrochemical voltage potentials between the cover layer and the substrate.
Die Zwischenschicht bildet als eine direkt auf das Substrat aufgebrachte und/oder in das Substrat eingebrachte korrosionsbeständige Schicht eine elektrochemische Barriere, so dass auf diese Weise Korrosionseigenschaften des Bauteils, insbesondere des Substrats, verbessert sind. Des Weiteren weist diese Zwischenschicht vorzugsweise einen mit dem Substrat zumindest weitgehend identischen Wärmeausdehnungskoeffizienten auf, so dass bei thermischen Ausdehnungszyklen, wie sie beispielsweise bei einem als Bremsscheibe für ein Fahrzeug ausgebildeten derartigen Bauteil auftreten, die Gefahr einer Rissentstehung aufgrund großer Abweichungen der Ausdehnungskoeffizienten nicht gegeben oder zumindest minimiert ist.The intermediate layer forms an electrochemical barrier as a corrosion-resistant layer applied directly to the substrate and / or introduced into the substrate, so that in this way corrosion properties of the component, in particular of the substrate, are improved. Furthermore, this intermediate layer preferably has a coefficient of thermal expansion which is at least largely identical to the substrate, so that there is no risk of crack formation due to large deviations of the expansion coefficients during thermal expansion cycles, as occur, for example, in the case of such a component designed as a brake disk for a vehicle is minimized.
Durch diese Verbesserung der Korrosions- und Rissbeständigkeit des Bauteils ist eine aus der Rissbildung resultierende mögliche Unterkorrosion, d. h. eine korrosive Unterwanderung der Deckschicht, welche zur Delamination bis zu einem möglichen Totalversagen des Schichtverbundes führt, unterbunden oder zumindest stark verzögert. Dadurch ist eine Standzeit und Lebensdauer des Bauteils, beispielsweise der Bremsscheibe, verlängert.This improvement in corrosion and crack resistance of the component results in possible undercorrosion resulting from cracking, i. H. a corrosive infiltration of the top layer, which leads to delamination to a possible total failure of the composite, prevented or at least greatly delayed. As a result, a service life and life of the component, such as the brake disc, extended.
