    Abstract: A method of applying a wear-resistant coating to aluminum sliding contact wear surfaces is disclosed. The method includes providing a plurality of parts having sliding contact wear surfaces and thermal spray coating at least one of a composite aluminum oxide and PTFE or a blend of aluminum oxide and PTFE. The disclosed method may be used to repair aluminum parts subject to sliding contact wear as well as in the design of new aluminum parts subject to sliding contact wear. Improved compressor bleed valves for gas turbine engines and improved fan exit case assemblies are also disclosed.

    Abstract: An improved thermal spray apparatus (100) and method of promotes mixing of axially fed particles in a earner stream with a heated effluent stream without introducing significant turbulence into either the effluent or carrier streams. An axial injection port (114) includes a plurality of chevrons (120) at the distal end of the port. The chevrons (120) are located radially around the circumference of the distal end of the axial injection port to increase the shared area between the two flow streams at the outlet of the port.

    Abstract: Plasma spraying of particulate thermotropic liquid crystalline polymers onto the surfaces (14) of composite and metallic structures. The present plasma spray process employs a conventional direct current electric arc plasma spray gun (12) in which an inert plasma gas is introduced, caused to swirl, and discharges as a rotating plasma flame having an exceptionally high temperature, above about 14000 DEG K, into which the particulate liquid crystal polymer is discharged for melting and propulsion onto the target surface (14). The target surface (14) preferably is preheated, and the molten particles deposit and cool to form a build up of the desired thickness. Cooling is regulated by post-heating the deposit to a temperature between about 200 DEG F and 500 DEG F.
