Abstract (de)

Die Erfindung bezieht sich auf die Ausstattung einer Turbinenschaufel (1) einer Gasturbine mit einem intermetallischen Filz (2). Durch die Besetzung der Spitze (11) der Turbinenschaufel (1) mit dem intermetallischen Filz (2) und einem Überzug mit einem keramischen Material (3) kann ein verbesserter Schutz gegen thermische und mechanische Einwirkungen und eine verbesserte Oxidationsbeständigkeit erreicht werden. Es ist auch eine Anordnung des intermetallischen Filzes (2) an dem der Turbinenschaufel (1) gegenüberliegenden Rotor (4, 4a) bzw. Stator (4, 4b) oder auf der Plattform (12) der Turbinenschaufel (1) denkbar. <IMAGE>
