  • Cooled turbine airfoils and methods of manufacture
    Publication number: 20070044936
    Abstract: An investment casting pattern is formed by installing a first core to a first element of a molding die to leave a first portion of the first core protruding from the first element. After the installing, the first element is assembled with a feed core and a second element of the molding die so that the first portion contacts the feed core. A material is molded at least partially over the first core and the feed core. The first portion has one or more surface area enhancements.

  • Method for casting cooling holes
    Publication number: 20070044935
    Abstract: A method for casting a cooled component includes molding a sacrificial pattern. A plurality of holes are formed through the pattern. A shell is formed over the pattern including filling the holes. The pattern is destructively removed from the shell. A metallic material is cast in the shell. The shell is destructively removed.

  • Hammerhead fluid seal
    Publication number: 20060275108
    Abstract: Disclosed are assemblies and articles for restricting leakage of a pressurized fluid from a cavity flanked by a vane support and a bladed rotor assembly. In accordance with an embodiment of the invention, the vane support defines a circumferential channel, and a interrupted rim region of the bladed rotor assembly defines a segmented ring. The segmented ring protrudes outward from the bladed rotor assembly, spans across the cavity and into the channel to define a seal.

  • Vapor deposition of dissimilar materials
    Publication number: 20060105195
    Abstract: A method for depositing a first material on a substrate includes providing the substrate in a deposition chamber. A molten body is formed between the substrate and a source of the first material by melting one or more second materials. A flow of the first material is passed through the molten body and from the molten body to the substrate as a vapor flow. An essentially non-expending portion of the molten body comprises an alloy having a melting temperature below a melting temperature of the first material.

  • Multi-component deposition
    Publication number: 20050205415
    Abstract: Ion-enhanced physical vapor deposition is augmented by sputtering to deposit multi-component materials. The process may be used to deposit coatings and repair material on Ti alloy turbine engine parts. The physical vapor deposition may be ion-enhanced electron beam physical vapor deposition.
