  • Ceramic thermal barrier coating with alumina interlayer
    Patent number: 5015502
    Abstract: A ceramic thermal barrier coating system for superalloy components subjected to high operating temperatures, such as gas turbine engine airfoils, includes a high purity alumina interfacial layer between the metallic substrate and the ceramic overcoat in order to better resist failure by spalling.
    Type: Grant
    Filed: November 8, 1989
    Date of Patent: May 14, 1991
    Assignee: Allied-Signal Inc.
    Inventors: Thomas E. Strangman, Patricia A. Solfest
