Abstract: A coating precursor slurry is provided, along with its methods of formation and use. The coating precursor slurry may include an organic binder comprising a polymeric component and a hardening reagent; an inorganic binder comprising an aluminum-nitrogen compound, a barium-containing organic compound, a nickel-containing organic compound, an ammonia polyphosphate, and phosphorus pentoxide; active components comprising Mo, Te, and graphite; and a solvent.

Abstract: A hollow component for gas turbine engine, for example an outlet guide vane, is assembled from a body having at recessed pocket formed therein, and an aerodynamic cover bonded over the pocket. Both the cover and the body are constructed from materials which are not readily fusion weldable. The cover is attached to the body by a solid state bonding process, for example friction stir welding. The hollow component may also be built up from multiple individual components which are bonded to each other by a solid state bonding process such as friction stir welding.

Abstract: A drive head for a bolt, fastener, coupling, nut or other driveable head made from a less malleable metal such as a powder metal nickel alloy. The drive head has an upper drive portion having at least six convex corners spaced around the outer periphery thereof, each corner terminating in an edge. The drive head also has a lower flange portion adjacent to the drive portion and having an edge extending radially outwardly to at least the edge of each corner. The drive portion and the flange portion of the drive head is formed by subjecting a blank having a generally circular head to electrochemical machining (ECM). A tool is also provided for the ECM method to form the drive portion and flange portion of the drive head.
