  • Patent number: 6365281
    Abstract: A turbine component, such as a turbine blade having a metal substrate (22) is coated with a metal MCrAlY alloy layer (24) and then a thermal barrier layer (20) selected from LaAlO3, NdAlO3, La2Hf2O7, Dy3Al5O12, HO3Al3O12, ErAlO3, GdAlO3, Yb2Ti2O7, LaYbO3, Gd2Hf2O7 or Y3Al5O12.
    Type: Grant
    Filed: September 24, 1999
    Date of Patent: April 2, 2002
    Assignee: Siemens Westinghouse Power Corporation
    Inventors: Ramesh Subramanian, Stephen M. Sabol, John G. Goedjen, Kelly M. Sloan, Steven J. Vance
  • Patent number: 6306515
    Abstract: The present invention generally describes multilayer coating systems comprising a composite metal/metal oxide bond coat layer. The coating systems may be used in gas turbines.
    Type: Grant
    Filed: August 12, 1998
    Date of Patent: October 23, 2001
    Assignee: Siemens Westinghouse Power Corporation
    Inventors: John G. Goedjen, Stephen M. Sabol, Kelly M. Sloan, Steven J. Vance
  • Patent number: 6129988
    Abstract: The present invention generally describes methods for modifying MCrAlY coatings by using gaseous carburization, gaseous nitriding or gaseous carbonitriding. The modified MCrAlY coatings are useful in thermal barrier coating systems, which may be used in gas turbine engines.
    Type: Grant

  • Patent number: 6106959
    Abstract: The present invention generally describes multilayer thermal barrier coating systems and methods of making the multilayer thermal barrier coating systems. The thermal barrier coating systems comprise a first ceramic layer, a second ceramic layer, a thermally grown oxide layer, a metallic bond coating layer and a substrate. The thermal barrier coating systems have improved high temperature thermal and chemical stability for use in gas turbine applications.
