  • Publication number: 20240158921
    Abstract: A composition includes aluminum (Al), and a blend of a carbide and nickel-chromium (Ni-20Cr). The method of applying a coating composition includes blending a carbide and nickel-chromium (Ni-20Cr) with aluminum (Al) to form a composition, the carbide and the nickel-chromium (Ni-20Cr) in a range between 90% and about 99.5% by weight of the composition, and wherein the aluminum (Al) is in a range between about 0.5% and less than about 10% by weight of the composition; and spraying the composition on the turbine component.

  • Patent number: 8031346
    Abstract: System and method for evaluating coating thickness variations along a turbine blade contour. In one embodiment, applied to a first region extending 360 degrees about the blade and to a second region including an exposed reference surface, the first region includes a first surface over which the coating is formed and a second surface formed by the coating. The system provides a source of structured light positionable to cast patterns suitable for determination of coordinate position information along the surfaces. One or more imaging cameras are positionable to acquire image data based on the light patterns. A computer system processes image information to (1) characterize the first and second surfaces with respect to a coordinate along the reference surface; (2) compare coordinate data corresponding to the first surface with coordinate data corresponding to the second surface; and (3) determine thickness of the coating as a function of position.
