Abstract:
(EN) The invention relates to a compressor blade (1) for a gas turbine (100). The compressor blade (1) has a blade substrate (2) that consists of a metal alloy and has an aluminum diffusion zone (3) on a surface of the blade substrate (2). In addition, the compressor blade (1) has a hard material coating (4) provided on the surface of the blade substrate (2). Other aspects of the invention relate to a compressor (105) that has such a compressor blade (1) and a method of producing such a compressor blade (1).
(FR) L'invention concerne une aube de compresseur (1) destinée une turbine à gaz (100). L'aube de compresseur (1) comporte un substrat d'aube (2) qui est constitué d'un alliage de métal et qui comporte sur une surface du substrat d'aube (2) une zone de diffusion d'aluminium (3). En outre, l'aube de compresseur (1) comporte un revêtement de matière dure (4) qui est disposé sur la surface du substrat d'aube (2). D'autres aspects de l'invention concernent un compresseur (105) équipé d'une telle aube de compresseur (1) et un procédé de fabrication d'une telle aube de compresseur (1).
(DE) Die Erfindung führt eine Verdichterschaufel (1) für eine Gasturbine (100) ein. Die Verdichterschaufel (1) verfügt über ein Schaufelsubstrat (2), das aus einer Metalllegierung besteht und an einer Oberfläche des Schaufelsubstrates (2) eine Aluminiumdiffusionszone (3) aufweist. Außerdem verfügt die Verdichterschaufel (1) über eine auf der Oberfläche des Schaufelsubstrates (2) angeordnete Hartstoffbeschichtung (4). Weitere Erfindungsaspekte betreffen einen Verdichter (105) mit einer solchen Verdichterschaufel (1) und ein Herstellungsverfahren für eine solche Verdichterschaufel (1).
