Die Figur 1 zeigt in perspektivischer Ansicht eine Laufschau¬ fel 120 oder Leitschaufel 130 einer Strömungsmaschine, die sich entlang einer Längsachse 121 erstreckt. Alloys are used according to Figure 4. 1 shows a perspective view of a rotor blade 120 or guide vane show ¬ 130 of a turbomachine, which extends along a longitudinal axis of the 121st
Die Strömungsmaschine kann eine Gasturbine eines Flugzeugs oder eines Kraftwerks zur Elektrizitätserzeugung, eine Dampfturbine oder ein Kompressor sein. Die Schaufel 120, 130 weist entlang der Längsachse 121 auf¬ einander folgend einen Befestigungsbereich 400, eine daran angrenzende Schaufelplattform 403 sowie ein Schaufelblatt 406 und eine Schaufelspitze 415 auf. The turbomachine may be a gas turbine of an aircraft or a power plant for power generation, a steam turbine or a compressor. The blade 120, 130 has along the longitudinal axis 121 to each other, a securing region 400, an adjoining blade or vane platform 403 and a blade 406 and a blade tip 415.
Als Leitschaufel 130 kann die Schaufel 130 an ihrer Schaufel- spitze 415 eine weitere Plattform aufweisen (nicht darge¬ stellt) . As a guide vane 130, the vane 130 may be pointed on its shovel 415 have a further platform (not Darge ¬ asserted).
Im Befestigungsbereich 400 ist ein Schaufelfuß 183 gebildet, der zur Befestigung der Laufschaufeln 120, 130 an einer Welle oder einer Scheibe dient (nicht dargestellt) . In the mounting region 400, a blade root 183 is formed, which serves for attachment of the blades 120, 130 to a shaft or a disc (not shown).
Der Schaufelfuß 183 ist beispielsweise als Hammerkopf ausge¬ staltet. Andere Ausgestaltungen als Tannenbaum- oder Schwalbenschwanzfuß sind möglich. The blade root 183 is, for example, as a hammerhead out staltet ¬. Other designs as Christmas tree or Schwalbenschwanzfuß are possible.
Die Schaufel 120, 130 weist für ein Medium, das an dem Schau- felblatt 406 vorbeiströmt, eine Anströmkante 409 und eine Ab¬ strömkante 412 auf. The blade 120, 130 has a medium felblatt to the Schau- 406 flows past, a leading edge 409 and a trailing edge 412th
Bei herkömmlichen Schaufeln 120, 130 werden in allen Bereichen 400, 403, 406 der Schaufel 120, 130 beispielsweise mas- sive metallische Werkstoffe, insbesondere Superlegierungen verwendet . In conventional blades 120, 130, in all regions 400, 403, 406 of the blade 120, 130, for example, massive metallic materials, in particular superalloys, are used.
Solche Superlegierungen sind beispielsweise aus der EP 1 204 776 Bl, EP 1 306 454, EP 1 319 729 AI, WO 99/67435 oder WO 00/44949 bekannt.  Such superalloys are known, for example, from EP 1 204 776 B1, EP 1 306 454, EP 1 319 729 A1, WO 99/67435 or WO 00/44949.
Die Schaufel 120, 130 kann hierbei durch ein Gussverfahren, auch mittels gerichteter Erstarrung, durch ein Schmiedeverfahren, durch ein Fräsverfahren oder Kombinationen daraus gefertigt sein. Werkstücke mit einkristalliner Struktur oder Strukturen werden als Bauteile für Maschinen eingesetzt, die im Betrieb hohen mechanischen, thermischen und/oder chemischen Belastun- gen ausgesetzt sind. The blade 120, 130 can be made by a casting process, also by directional solidification, by a forging process, by a milling process or combinations thereof. Workpieces with a monocrystalline structure or structures are used as components for machines which are exposed to high mechanical, thermal and / or chemical stresses during operation.
Die Fertigung von derartigen einkristallinen Werkstücken erfolgt z.B. durch gerichtetes Erstarren aus der Schmelze. Es handelt sich dabei um Gießverfahren, bei denen die flüssige metallische Legierung zur einkristallinen Struktur, d.h. zum einkristallinen Werkstück, oder gerichtet erstarrt.  The production of such monocrystalline workpieces takes place e.g. by directed solidification from the melt. These are casting processes in which the liquid metallic alloy is transformed into a monocrystalline structure, i. to the single-crystal workpiece, or directionally solidified.
Dabei werden dendritische Kristalle entlang dem Wärmefluss ausgerichtet und bilden entweder eine stängelkristalline Kornstruktur (kolumnar, d.h. Körner, die über die ganze Länge des Werkstückes verlaufen und hier, dem allgemeinen Sprach- gebrauch nach, als gerichtet erstarrt bezeichnet werden) oder eine einkristalline Struktur, d.h. das ganze Werkstück be¬ steht aus einem einzigen Kristall. In diesen Verfahren muss man den Übergang zur globulitischen (polykristallinen) Erstarrung meiden, da sich durch ungerichtetes Wachstum notwen- digerweise transversale und longitudinale Korngrenzen ausbil¬ den, welche die guten Eigenschaften des gerichtet erstarrten oder einkristallinen Bauteiles zunichte machen. Here, dendritic crystals are aligned along the heat flow and form either a columnar grain structure (columnar, ie grains which extend over the entire length of the workpiece and here, for general language use, referred to as directionally solidified) or a monocrystalline structure, ie the entire workpiece ¬ is of a single crystal. In these methods, you have to transition to globular (polycrystalline) solidification avoided, since non-directional growth inevitably forms transverse and longitudinal grain boundaries ¬ which solidified the directionally the good qualities or monocrystalline component nullify.
Ist allgemein von gerichtet erstarrten Gefügen die Rede, so sind damit sowohl Einkristalle gemeint, die keine Korngrenzen oder höchstens Kleinwinkelkorngrenzen aufweisen, als auchIs generally speaking of directionally solidified structures speech, so are both single crystals meant that have no grain boundaries or at most small angle grain boundaries, as well
Stängelkristallstrukturen, die wohl in longitudinaler Richtung verlaufende Korngrenzen, aber keine transversalen Korngrenzen aufweisen. Bei diesen zweitgenannten kristallinen Strukturen spricht man auch von gerichtet erstarrten Gefügen (directionally solidified structures) . Stem-crystal structures, which probably have longitudinally extending grain boundaries, but no transverse grain boundaries. These second-mentioned crystalline structures are also known as directionally solidified structures.
Solche Verfahren sind aus der US-PS 6,024,792 und der EP 0 892 090 AI bekannt.  Such methods are known from US Pat. No. 6,024,792 and EP 0 892 090 A1.

Die Figur 2 zeigt eine Brennkammer 110 einer Gasturbine. FIG. 2 shows a combustion chamber 110 of a gas turbine.
Die Brennkammer 110 ist beispielsweise als so genannte Ring¬ brennkammer ausgestaltet, bei der eine Vielzahl von in Um- fangsrichtung um eine Rotationsachse 102 herum angeordneten Brennern 107 in einen gemeinsamen Brennkammerraum 154 münden, die Flammen 156 erzeugen. Dazu ist die Brennkammer 110 in ihrer Gesamtheit als ringförmige Struktur ausgestaltet, die um die Rotationsachse 102 herum positioniert ist. The combustion chamber 110 is configured, for example, as so-called an annular combustion chamber, in which a plurality of in the circumferential direction about an axis of rotation 102 arranged burners 107 open into a common combustion chamber space 154 and generate flames 156th For this purpose, the combustion chamber 110 is configured in its entirety as an annular structure, which is positioned around the axis of rotation 102 around.
Zur Erzielung eines vergleichsweise hohen Wirkungsgrades ist die Brennkammer 110 für eine vergleichsweise hohe Temperatur des Arbeitsmediums M von etwa 1000°C bis 1600°C ausgelegt. Um auch bei diesen, für die Materialien ungünstigen Betriebsparametern eine vergleichsweise lange Betriebsdauer zu ermög¬ lichen, ist die Brennkammerwand 153 auf ihrer dem Arbeitsme- dium M zugewandten Seite mit einer aus Hitzeschildelementen 155 gebildeten Innenauskleidung versehen. To achieve a comparatively high efficiency, the combustion chamber 110 is designed for a comparatively high temperature of the working medium M of about 1000 ° C to 1600 ° C. To even with these operating parameters unfavorable for the materials, a comparatively long operating time to be made ¬ union, the combustion chamber wall 153 is provided on its side facing the medium M, Arbeitsme- facing side with a formed from heat shield elements 155. liner.

Die Wärme¬ dämmschicht kann poröse, mikro- oder makrorissbehaftete Kör- ner zur besseren Thermoschockbeständigkeit aufweisen. Other coating methods are conceivable, for example atmospheric plasma spraying (APS), LPPS, VPS or CVD. The heat insulating layer can ¬ ner to have better thermal shock resistance porous, micro- or macro-cracked pERSonal.
Wiederaufarbeitung (Refurbishment ) bedeutet, dass Hitze¬ schildelemente 155 nach ihrem Einsatz gegebenenfalls von Schutzschichten befreit werden müssen (z.B. durch Sandstrah- len) . Danach erfolgt eine Entfernung der Korrosions- und/oder Oxidationsschichten bzw. -produkte. Gegebenenfalls werden auch noch Risse in dem Hitzeschildelement 155 repariert. Reprocessing (Refurbishment) means that heat shield elements may need to be removed 155 after use of protective layers (for example by sandblasting). This is followed by removal of the corrosion and / or oxidation layers or products. If necessary, cracks in the heat shield element 155 are also repaired.
Danach erfolgt eine Wiederbeschichtung der Hitzeschildelemente 155 und ein erneuter Einsatz der Hitzeschildelemente 155. This is followed by a recoating of the heat shield elements 155 and a renewed use of the heat shield elements 155.
Aufgrund der hohen Temperaturen im Inneren der Brennkammer 110 kann zudem für die Hitzeschildelemente 155 bzw. für deren Halteelemente ein Kühlsystem vorgesehen sein. Die Hitze- schildelemente 155 sind dann beispielsweise hohl und weisen ggf. noch in den Brennkammerraum 154 mündende Kühllöcher (nicht dargestellt) auf. Due to the high temperatures inside the combustion chamber 110 may also be provided for the heat shield elements 155 and for their holding elements, a cooling system. The heat shield elements 155 are then, for example, hollow and may still have cooling holes (not shown) which open into the combustion chamber space 154.
