  • Method for repairing a single crystal turbine blade
    Patent number: 9488053
    Abstract: A method is provided for repairing a single crystal turbine blade, which includes an airfoil with a tip having a tip cover plate, tip cooling air holes and a tip crown. The method includes removing the tip crown by manual grinding, thereby preserving the underlying tip cover plate; preparing the tip cooling air holes by manual grinding; closing said prepared tip cooling air holes by manual welding; and building-up a new tip crown by a LMF (Laser Metal Forming) process.
    Type: Grant
    Filed: January 7, 2015
    Date of Patent: November 8, 2016
    Assignee: GENERAL ELECTRIC TECHNOLOGY GMBH
    Inventors: Tobias Schmitt, Hans Bissig, Stefan Schlegel, Guenter Ambrosy, Michael Seemann, Hermann Emminger

  • Method for measuring a thickness of a coating
    Patent number: 7319531
    Abstract: A method for measuring a thickness of a coating of a constructional unit, in particular a heat-compatible coating on a component of a gas turbine, includes measuring coordinates of the constructional unit three-dimensionally with a measuring device, in particular an optical scanner, before and after the coating, a thermal distortion of the constructional unit being recorded during the coating and the thickness of the coating being determined from a comparison of the measured constructional unit coordinates before and after the coating. The thermal distortion of the constructional unit is taken into account in the thickness determination of the coating by a comparison with at least one reference point at an uncoated location.
