  • Coated article and method for inhibiting frictional wear between mating titanium alloy substrates in a gas turbine engine
    Patent number: 6158963
    Abstract: A pair of mating titanium alloy substrates for use in a gas turbine engine are provided, one of which comprises an aluminum bronze alloy wear resistant coating. The coating consists essentially of 9.0-11.0% aluminum (Al), 0.0-1.50% iron (Fe), and a remainder of copper (Cu). The wear resistant coating is disposed between the mating substrates and inhibits frictional wear between the mating substrates.
    Type: Grant
    Filed: November 1, 1999
    Date of Patent: December 12, 2000
    Assignee: United Technologies Corporation
    Inventors: Terry L. Hollis, Thomas J. Rising, John G. Dorrance, Bruce I. Beeman, Jr.

  • Axial load carrying brush seal
    Patent number: 5480162
    Abstract: A brush seal consisting of a annular backing plate, annular side plate and a bundle of bristles disposed axially sandwiched in between serve to transmit the axial load when assembled and eliminate the necessity of seal retaining mechanism such as split rings or retaining plates. The invention is particularly adapted to seal the interface of the combustor and the stator of the first stage turbine of a gas turbine engine.
