  • TURBINE IMPELLER
    Publication number: 20210215052
    Abstract: A turbine impeller includes: a base material which contains aluminum as a main element; and an anti-erosion coating which covers a surface of the base material. Accordingly, since liquid droplets hit the anti-erosion coating before the base material even when the liquid droplets flow into the rotating turbine impeller, the damage to the base material due to erosion is suppressed.
