  • Elevated temperature oxidation protection coatings for titanium alloys and methods of preparing the same
    Patent number: 7135238
    Abstract: Oxidation protection of a titanium-based alloy is provided with improved fatigue properties by a titanium aluminide coating of between 2 to 12 microns by diffusing the Al into the Ti at a temperature below the melting point of the Al. The coating is gas deposited and protects the titanium-based alloys from oxidation at high temperature utilization.
    Type: Grant
    Filed: October 29, 2004
    Date of Patent: November 14, 2006
    Assignee: Honeywell International, Inc.
    Inventors: Derek Raybould, Paul Chipko, William E. Fischer

  • Thermal barrier coating with alumina bond inhibitor
    Patent number: 6103386
    Abstract: A thermal barrier coating for superalloy turbine engine vanes and blades that are exposed to high temperature gas is disclosed. The coating includes an aluminide or MCrAlY layer, an alumina layer, and a ceramic top layer. The ceramic layer has a columnar grain microstructure. A bond inhibitor is disposed in the gaps between the columnar grains. This inhibitor is preferably alumina.
