  • Patent number: 10124408
    Abstract: A method and apparatus for fabricating an object. The method and apparatus entail applying a pulsed laser energy to a first quantity of a powder material on a substrate so as to fuse particles of the powder material into a first layer on the substrate, and then forming at least one additional layer on the first layer by applying a pulsed laser energy to at least a second quantity of the powder material on the first layer so as to fuse particles of the powder material into the at least one additional layer on the first layer. The pulsed laser energy is applied in a controlled manner such that solidification dynamics of the first and second quantities of the powder material are altered to promote at least one microstructural characteristic of the first and additional layer.

  • Patent number: 10125632
    Abstract: Cooling air extracted from a gas turbine engine compressor is sent to a nozzle vane cooling passage inlet, through the cooling passage, and to a purge tube of the vane. A mixing chamber formed in a diaphragm cavity receives fluid from the purge tube and directs it through exit passage(s) formed through a side wall of the mixing chamber and/or diaphragm cavity to a diametral surface of the diaphragm. The exit passage(s) can be inclined to induce a fluid velocity component substantially parallel to the diametral surface and/or in a rotation direction of a turbine wheel adjacent the diaphragm.

  • Patent number: 10125425
    Abstract: Stripping a metallic bond coat from an article using a wet chemical process. An article removed from service and having a metallic bond coat applied over a surface of its metallic substrate is provided. The metallic bond coat is used to improve the adhesion of a TBC to the article, so grit blasting to first remove any TBC applied over the bond coat and which still remains on the article initially may be required. The bond coated article is then immersed in an acid solution of HCl/H3PO4 at a predetermined temperature for a predetermined amount of time, the HCl/H3PO4 solution reacting with the bond coat applied over the metallic substrate to form a smut on the surface. The article is then removed from the HCl/H3PO4 solution and quickly immersed in a solution of NaOH for a predetermined amount of time to at least partially desmut the surface.
