Summary:This turbine impeller comprises: a base material the main component of which is aluminum; and an anti-erosion coating that covers the surface of the base material. Due to this configuration, even if liquid droplets flow into the rotating turbine impeller, the liquid droplets come into contact with the anti-erosion coating before the base material, and as a result, damage to the base material due to erosion is prevented. Roue de turbine comprenant : un matériau de base dont le composant principal est l'aluminium; et un revêtement anti-érosion qui recouvre la surface du matériau de base. Grâce à cette configuration, même si des gouttelettes de liquide s'écoulent dans la roue de turbine en rotation, elles entrent en contact d'abord avec le revêtement anti-érosion avant le matériau de base, et, par conséquent, un endommagement du matériau de base dû à l'érosion est empêché. タービンインペラは、主成分をアルミニウムとする母材と、母材の表面を覆う耐エロージョン被膜部と、を備える。これにより、回転するタービンインペラに液滴が流入しても、母材より先に耐エロージョン被膜部に液滴があたるので、エロージョンによって母材が損傷することが抑制される。
