Description

Die Erfindung betrifft eine Anordnung aus einer Keramik, die auf einem metallischen Substrat angebunden werden soll, bei dem eine duktile Zwischenschicht aus Metall verwendet wird.The invention relates to an arrangement of a ceramic to be bonded to a metallic substrate, wherein a ductile intermediate layer of metal is used.

Keramik wie CMC-Materialien oder Komponenten sind faserverstärkte Matrixen, bei denen keramische Fasern wie Siliziumkarbidfasern, Aluminiumoxidfasern, Mullitfasern und/oder Aluminiumoxidmullitfasern in einer keramischen Matrix wie Siliziumkarbid, Aluminiumoxid, Mullit oder Aluminiumoxidmullit eingebettet sind. Diese Materialien weisen eine hohe Temperaturfestigkeit auf und werden in Gasturbinen bei Einsatz höherer Temperaturen benötigt.Ceramics such as CMC materials or components are fiber-reinforced matrices in which ceramic fibers such as silicon carbide fibers, alumina fibers, mullite fibers and / or alumina mullite fibers are embedded in a ceramic matrix such as silicon carbide, alumina, mullite or alumina mullite. These materials have a high temperature resistance and are required in gas turbines when using higher temperatures.

In der Regel verwendet man keine massiven Bauteile aus CMC, sondern bringt die CMC nur in dem äußeren Bereich auf, so dass das CMC-Bauteil mit einer metallischen Struktur verbunden werden muss.As a rule, one does not use massive CMC components, but applies the CMC only in the outer area, so that the CMC component must be connected to a metallic structure.

Beim Fügen durch Hochtemperaturlöten von Metall und Keramik entstehen thermisch induzierte Spannungen im Bereich der Lötverbindung, durch das unterschiedliche Wärmeausdehnungsverhalten beider Werkstoffe. Diese Spannungen senken die Festigkeit der Verbindung oder führen gar zur Delamination bzw. Zerstörung insbesondere bei faserverstärkten Keramikwerkstoffen (CMCs).When joining by high-temperature soldering of metal and ceramic arise thermally induced stresses in the solder joint, due to the different thermal expansion behavior of both materials. These stresses reduce the strength of the compound or even lead to delamination or destruction, especially in fiber-reinforced ceramic materials (CMCs).

Das Problem wurde bisher durch die Verwendung von duktilen, massiven Zwischenschichten gelöst, die durch elastische oder gar plastische Verformung eine Relaxation der spannungsbehafteten Lötverbindung herbeiführen. Diese Pufferschichten - auf der Basis Cu / Ag basiert weisen aber eine geringe Oxidationsbeständigkeit auf.The problem has been solved by the use of ductile, massive intermediate layers, which cause elastic or even plastic deformation relaxation of the voltage-sensitive solder joint. These buffer layers - based on Cu / Ag based but have a low oxidation resistance.

Es ist daher Aufgabe der Erfindung oben genanntes Problem zu lösen.It is therefore an object of the invention to solve the above-mentioned problem.

Die Aufgabe wird gelöst durch einen Aufbau gemäß Anspruch 1 und durch ein Verfahren nach Anspruch 2.The object is achieved by a structure according to claim 1 and by a method according to claim 2.

Das Problem wird durch eine duktile Zwischenlage aus metallischen Schäumen oder andere metallische zellulare Strukturen gelöst.The problem is solved by a ductile intermediate layer of metallic foams or other metallic cellular structures.

In den Unteransprüchen sind weitere vorteilhafte Maßnahmen aufgelistet, die beliebig miteinander kombiniert werden können, um weitere Vorteile zu erzielen.In the dependent claims further advantageous measures are listed, which can be combined with each other in order to achieve further advantages.

Die Figur zeigt schematisch den erfindungsgemäßen Aufbau.The figure shows schematically the structure according to the invention.

Die Figur und die Beschreibung stellen nur Ausführungsbeispiele der Erfindung dar.The figure and the description represent only embodiments of the invention.

Durch eine regellose Struktur und die intrinsische Verformbarkeit, insbesondere metallischer Fließe können die durch die thermische Ausdehnung auftretenden Relativbewegungen der zu verbindenden Werkstoffe ausgeglichen werden. Das metallische Fließ wird vorzugsweise mit handelsüblichen Loten an die metallische Komponente gelötet werden und vorzugsweise mittels Aktivlöten mit der Keramischen Komponente verbunden werden.Due to a random structure and the intrinsic deformability, in particular metallic flow, the relative movements of the materials to be joined which occur due to the thermal expansion can be compensated. The metallic flux will preferably be soldered to the metallic component with commercially available solders and preferably connected to the ceramic component by means of active soldering.

Die Unterschiede der thermischen Dehnung beim Abkühlen nach dem Lötprozess kann von dem metallischen Fließ durch dessen Verformungsvermögen kompensiert werden ohne das die Lötverbindung gelöst oder die Keramik (bzw. CMC) beschädigt wird.The differences of the thermal expansion during cooling after the soldering process can be compensated by the metallic flow by its deformability without the solder joint dissolved or the ceramic (or CMC) is damaged.

Die metallischen Fließe können aus verschiedensten Materialien hergestellt werden, wie etwa auf Eisen- und Nickelbasis. Dadurch können diese duktilen Zwischenschichten, anders als jede vollmaterialein auf Basis von Kupfer oder Silber, bei hohen Temperaturen eingesetzt werden. Die Fließe sind in verschiedenen Dicken herstellbar, einfach und präzise zu verarbeiten und gut verfügbar.The metallic flows can be made of a variety of materials, such as iron and nickel based. As a result, these ductile interlayers, unlike any solid based on copper or silver, can be used at high temperatures. The flows can be produced in various thicknesses, simple and precise to process and well available.

Auf makroskopischer Ebene weisen die metallischen Fließe die geforderten mechanischen Eigenschaften für die Spannungskompensation auf.At the macroscopic level, the metallic flows have the required mechanical properties for stress compensation.

Die Erfindung ermöglicht die Verbindung von Metall und Keramik auf eine relativ einfache und fertigungstechnisch gut umsetzbare Art und Weise. Diese Verbindung kann bis zu hohen Temperaturen Einsatz finden.The invention allows the connection of metal and ceramic in a relatively simple and manufacturable well implementable way. This compound can be used up to high temperatures.

In der Figur ist ein erfindungsgemäßes Hybridbauteil 1 dargestellt.In the figure is a hybrid component according to the invention 1 shown.

Das Material der Zwischenlage 7 kann dasselbe sein wie das des Substrats 4 oder ist von dem Material des Substrats 4 verschieden. Verschieden bedeutet, dass zumindest ein anderes Legierungselement mehr oder weniger vorhanden ist oder die Unterschiede in zumindest einem Legierungselement mindestens 10%, insbesondere 20% betragen.The material of the liner 7 may be the same as that of the substrate 4 or is of the material of the substrate 4 different. Different means that at least one other alloying element is more or less present or the differences in at least one alloying element amount to at least 10%, in particular 20%.

Es eignen sich für die Zwischenlage die Werkstoffe 1.4404 (X2CrNiMo17-12-2) und 1.4841 (X15CrNiSi25-21). Neben diesen hochlegierten Stählen sind auch Fließe auf Nickelbasis wie INCONEL 625, Hastelloy X oder auf Kobaltbasis denkbar und insbesondere bei Hochtemperaturanwendungen zielführend.The materials 1.4404 (X2CrNiMo17-12-2) and 1.4841 (X15CrNiSi25-21) are suitable for the intermediate layer. In addition to these high-alloyed steels are also nickel-based flows such as INCONEL 625 , Hastelloy X or cobalt-based conceivable and in particular in high-temperature applications expedient.

Die metallische Zwischenlage 7 wird vorzugsweise durch ein metallisches Lot mit dem Substrat 4 verbunden.The metallic liner 7 is preferably by a metallic solder with the substrate 4 connected.

Vorzugsweise kann durch additive Herstellungsverfahren die Zwischenlage 7 direkt auf dem Substrat 4 aufgebracht und hergestellt werden, dann insbesondere ohne Verwendung von Metalllot. Dies sind Laser-Auftragschweißverfahren oder Selektive Laser Melting oder Selektive Laser Sintering.Preferably, by additive manufacturing process, the intermediate layer 7 directly on the substrate 4 applied and manufactured, then in particular without the use of Metalllot. These are Laser Deposition Welding or Selective Laser Melting or Selective Laser Sintering.
