Abstract: A method of repairing a worn carburized surface on a sprag clutch comprising the steps of: grinding the worn carburized surface of the sprag clutch to prepare the surface for metallurgical bonding; place the worn carburized surface in a PVD Cathodic Arc chamber; preheat the worn carburized surface to remove moisture and provide for a good metallurgical bonding surface; reverse sputter clean the surface to remove any surface oxide; apply a first coating layer using the PVD process to a maximum thickness; change the coating macro topology by polishing the coated surface; apply a second coating layer using the PVD process to a maximum thickness; and, grind or polish the coating to a desired dimension.

Abstract: An air cooled turbine airfoil with an impingement plate bonded over multiple impingement cooling surfaces of the airfoil, where the impingement plate forms a series of double or triple impingement cooling for separate surfaces of the airfoil. The impingement plate can be shaped and sized to fit over an airfoil surface that requires multiple impingement cooling.

Abstract: An air riding seal between a rotor and a stator in a turbine of a gas turbine engine, where an annular piston is movable in an axial direction within a housing that extends from the stator, and a bellows is secured to the annular piston to form a flexible air passageway from a compressed air inlet through the annular piston and into a cushion cavity that forms an air riding seal between the annular piston and the rotor sealing surface. In another embodiment, a flexible seal secured to and extending from the annular piston forms a sealing surface between the annular piston chamber and the annular piston to provide a seal and allow for axial movement.

Abstract: A turbine rotor blade of the spar and shell construction, the spar including a tip end with a dovetail shaped groove extending from the top, and a tip cap includes a dovetail shaped slot that engages with the spar groove to retain the tip cap in place. A shell made from a high temperature resistant material is secured in place between the platform and the tip cap. The platform includes a core extending into a hollow space formed by the shell and discharges impingement cooling air against the backside wall of the shell. The spar and the platform include fir tree configurations so that an assembled blade can be inserted into a slot of a rotor disk.
