    Abstract: A seal assembly between a rotor and a stator is disclosed. In one embodiment, the seal assembly includes: a rotor; a stator positioned around the rotor; and a plurality of seal leaves positioned between the rotor and the stator, the plurality of seal leaves circumferentially stacked around the rotor to define a seal ring between the rotor and the stator, wherein gaps between adjacent seal leaves are partially filled, such that contact faces and residual gaps are between adjacent seal leaves, wherein the contact faces generate friction to dampen vibrations during operation. Such damping effects still allow the compliant motion of the seal leaves with minimal leaf vibration. Also, thicker and more resilient leaves may be applied with reduced leakage through the root gaps.

    Abstract: Electrodes for and methods of electrical discharge machining are provided. For example, a method for forming a feature in a ceramic matrix composite (CMC) component comprises repeatedly advancing an electrode into and retracting the electrode from the CMC component until a desired depth is reached, where the electrode has a head end, a tip end, and a shaft extending from the head end to the tip end. The shaft has a first side and a second side each recessed inward such that the head end and the tip end are wider than the shaft. A method for forming a feature in a CMC component also may include feeding a dielectric fluid into the feature utilizing the recessed sides. In some embodiments, electrodes may include a shaft extending from a head end to a tip end and a central plane, where the shaft is recessed widthwise toward the central plane.

    Abstract: Various embodiments include a sealed laminated metal structure. This laminated metal structure has a metal layer, where the metal layer has a first surface and an opposite second surface. A material is laminated on each of the first and second surfaces of the metal layer. In some cases, the laminated metal structure is removed from a larger laminated sheet of metal. The laminated metal structure is subjected to alternating current electrolytic deburring and cleaning to remove any burrs along the perimeter edge. After deburring and cleaning, a sealer, which is a phosphate compound, is deposited on the perimeter edge of the laminated metal structure where the metal is exposed using alternating current.
