  • Nickel-base superalloys especially useful as compatible protective environmental coatings for advanced superaloys
    Patent number: 5035958
    Abstract: There is provided by the present invention an alloy which is mechanically and chemically compatible with advanced nickel-base superalloys and nickel-base eutectic superalloys and which possesses excellent resistance to high temperature oxidation. The alloy of the invention is, therefore, particularly useful as a protective environmental coating for the external surfaces of hot-stage aircraft gas turbine engine components, e.g., rotating blades and stationary vanes, made from such advanced superalloys.
    Type: Grant
    Filed: October 11, 1989
    Date of Patent: July 30, 1991
    Assignee: General Electric Company
    Inventors: Melvin R. Jackson, Mark L. Prugar, Swe-Wong Yang, John R. Rairden, III, Michael F. X. Gigliotti, Jr.
  • Carbide reinforced nickel-base superalloy eutectics having improved resistance to surface carbide formation
    Patent number: 4589937
    Abstract: Monocarbide reinforced nickel-base eutectic superalloys which are particularly characterized by improved resistance to the formation of surface nucleated carbides and are, therefore, especially suited for making unidirectionally solidified anisotropic metallic bodies in the form of vanes and rotating blades for aircraft gas turbine engines are provided.
    Type: Grant
    Filed: September 22, 1982
    Date of Patent: May 20, 1986
    Assignee: General Electric Company
    Inventors: Melvin R. Jackson, Michael F. X. Gigliotti, Jr., Swe-Wong Yang
  • Phase stable carbide reinforced nickel-base superalloy eutectics having improved high temperature stress-rupture strength and improved resistance to surface carbide formation
    Patent number: 4522664
    Abstract: Monocarbide reinforced nickel-base eutectic superalloys which are substantially phase stable and have improved high temperature stress-rupture strength with improved resistance to the formation of surface nucleated carbides are provided. These superalloys are especially suited for making unidirectionally solidified anisotropic metallic bodies in the form of vanes and rotating blades for aircraft gas turbine engines.
