Abstract:
A bushing for a stator vane assembly of a gas turbine engine has a tubular member that is coaxial about a longitudinal axis and that extends a length between a first axial end and a second axial end. The tubular member has an outside circumferential surface thereon and an inside circumferential surface therein and is manufactured from a cobalt based alloy, a nickel based alloy, a graphite material, a cermet material or an alloy matrix comprising titanium, aluminum, niobium, manganese, boron, and carbon and a solid lubricant being dispersed in the alloy matrix. A portion of the inside circumferential surface and/or a portion of the outside circumferential surface has a wear resistant material thereon.
