  • Ceramic thermal barrier coating system with two ceramic layers
    Patent number: 9567664
    Abstract: A thermal barrier coating including a two layered ceramic barrier coating, an inner ceramic layer and an outer ceramic layer, is provided. The thermal barrier coating has different thicknesses on different places of the component. In addition, the thickness of the inner ceramic layer and the thickness of the outer ceramic layer vary in relation to one another.

  • Method For Coating A Component With Film Cooling Holes And Component
    Publication number: 20120088064
    Abstract: During the complete masking of film cooling holes when coating a component with film cooling holes, problems frequently arise when the cooling gas exits from the film cooling hole. The method is provided which proposes that the masking is only carried out sectionally such that part of the coating is present in the film cooling hole. Thus the flow may still form like a film on the component.

  • Method for smoothing the surface of a gas turbine blade
    Patent number: 7144302
    Abstract: A surface of the gas turbine blade is smoothed by way of a drag finish process. A first ring-shaped container is filled with a liquid abrasive medium. A second container which is arranged next to the first container is filled with a second liquid abrasive medium. A pivoting arm is arranged between and above the containers and can be pivoted along a pivoting direction. A drag device is arranged on the pivoting arm. The drag device leads a gas turbine blade on a carrier arm through the abrasive medium.
