Die Erfindung betrifft ein Verfahren zum Herstellen einer Panzerung für ein metallisches Bauteil, die auf dessen Oberfläche vorgesehen wird.The invention relates to a method for producing an armor for a metallic Component provided on its surface.
Panzerungen bzw. Anstreifbeläge werden z.B. an Triebwerksbauteilen, wie z.B. Dichtungsspitzen von Labyrinthdichtungen oder Schaufelspitzen, vorgesehen, um deren Abarbeitung bei Anstreifvorgängen während des Betriebs entgegenzuwirken. Da der Wirkungsgrad eines Verdichters oder einer Turbine in hohem Maße von der Spaltgröße zwischen dem rotierenden und dem stehenden Bauteil abhängt, wird er mit zunehmender Abarbeitung, z.B. der Schaufelspitzen, vermindert.Armor or scratches are e.g. on engine components, e.g. seal tips of labyrinth seals or blade tips, provided to their Counteract processing during touch-ups during operation. Since the Efficiency of a compressor or turbine to a large extent on the gap size between the rotating and the stationary component, he is with increasing processing, e.g. the blade tips, reduced.
Die Panzerung arbeitet sich beim Betrieb des Triebwerks üblicherweise in einen Einlaufbelag eines gegenüberliegenden, zweiten Bauteils ein. Derartige Einlaufbeläge sind abreibbar und bestehen meist aus einer korrosions- und erosionsfesten Schicht. Eine Panzerung des Triebwerksbauteils ist insbesondere dann erforderlich, wenn die Festigkeit und Härte der Einlaufbeläge zur Steigerung der Erosions- und Temperaturbeständigkeit erhöht wird und sich die Abarbeitung der Triebwerksbauteile zusätzlich verstärkt. Durch die Panzerung wird erreicht, daß beim Anstreifvorgang ein minimaler Spalt zwischen der Panzerung und dem Einlaufbelag gebildet wird.The armor works in the operation of the engine usually in an inlet lining an opposite, second component. Such inlet linings are abradable and usually consist of a corrosion and erosion resistant layer. An armor of the engine component is required in particular when the Strength and hardness of the inlet coverings to increase erosion and temperature resistance is increased and the processing of engine components in addition strengthened. By the armor is achieved that the Anstreifvorgang a minimum Gap between the armor and the inlet lining is formed.
Bei einem bekannten Verfahren zum Herstellen einer Panzerung wird ein MCrAlY-Pulver durch galvanisches Auftragen auf das zu panzernde Bauteil aufgebracht, wobei in dem Bad die erforderlichen harten Partikel, wie z.B. BN, enthalten sind. Diese Partikel werden nach dem Auftragen freigeätzt. Ein solches Verfahren ist teuer und aufwendig. Insbesondere das anschließende Ätzen ist aufgrund der mangelnden Umweltverträglichkeit und dem erforderlichen Abdecken des Bauteils nachteilig.In one known method for making armor, an MCrAlY powder is used applied by electroplating on the component to be coated, wherein in the bath, the required hard particles, e.g. BN, are included. These Particles are etched free after application. Such a method is expensive and consuming. In particular, the subsequent etching is due to the lack of Environmental compatibility and the required covering of the component disadvantageous.
Bei einem anderen bekannten Verfahren wird eine an die Bauteilkontur angepaßte Lotfolie durch Kleben od dgl. an dem Bauteil befestigt. Danach werden BN-Partikel in die Lotfolie eingesetzt. Anschließend wird die Lotfolie durch Wärmebehandlung geschmolzen und die BN-Partikel darin eingebettet. Auch dieses Verfahren ist verhältnismäßig teuer und aufwendig. Zudem ist die Verbindung zwischen den Partikeln und dem Bauteil unzureichend.In another known method, one adapted to the component contour Lotfolie by gluing or the like. Attached to the component. Thereafter, BN particles in the solder foil used. Subsequently, the solder foil is melted by heat treatment and the BN particles embedded therein.

Anschließend folgt eine Schicht aus einem mit einem Binder versehenen Ni-Pulver, eine Wärmebehandlung und ein Alitieren durch ein Packverfahren. Dabei soll die erste Schicht aus der Keramik enthaltenden Mischung verhindern, daß Al von der Schicht in das Substrat eindringt und die Schicht mithin durch die Verarmung von Al ihre Wärmebeständigkeit einbüßt.It is known from JP 55-82765 A, which consists of a Ni or Co base alloy Substrate first with a mixture of ceramic, Al and metal powder To coat, the heat resistance of the long-lasting high temperature loaded Layer to improve.
