Gas Distributor For Vapor Coating Method And Container
US Patent:
6986814, Jan 17, 2006
Filed:
Dec 20, 2001
Appl. No.:
10/029311
Inventors:
Gary E. Wheat - Madisonville KY, US
Terri K. Brown - Central City KY, US

Assignee:
General Electric Company - Schenectady NY
International Classification:
C23G 16/00
US Classification:
118726, 118715
Abstract:
A gas distributor suitable for introducing a carrier gas at the top of a coating container used to provide a metallic coating on articles. The gas distributor includes a gas inlet and a gas outlet head in communication with the gas inlet for receiving a flow of gas from the gas inlet. A plurality of gas outlets through which the gas flow exits as a gas stream are spaced along the peripheral surface of the gas outlet head. A plurality of gas deflectors, each proximate to one of the gas outlets, at least initially direct the gas stream exiting the gas outlet in at least a generally centripetal path. This gas distributor can be used in vapor coating apparatus having a coating container, at least one holder for each article to be coated positioned within the coating container and below the gas outlet head of the gas distributor and at least one holder for the source of the metallic coating positioned within the coating container and below the gas outlet head of the gas distributor. A method is also provided for introducing the carrier gas as a plurality of carrier gas streams proximate the top of the coating container so that each carrier gas stream flows at least initially in at least a generally centripetal path, as well as a method for coating the articles with a metallic coating in the coating container.

Turbine Blade With Recessed Squealer Tip And Shelf
US Patent:
6991430, Jan 31, 2006
Filed:
Apr 7, 2003

Assignee:
General Electric Company - Schenectady NY
International Classification:
F01D 5/18
US Classification:
416 97R, 415115, 4151731, 416 92, 416228
Abstract:
A turbine blade squealer tip has a continuous squealer tip wall extending radially outwardly from and continuously around a tip cap. A recessed tip wall portion of the tip wall is recessed inboard from a pressure side of an airfoil outer wall of an airfoil of the blade forming a tip shelf therebetween. A plurality of film cooling shelf holes are disposed through the tip shelf to an internal cooling circuit of the blade and are spaced away from a junction between the recessed tip wall portion and the tip shelf. The exemplary embodiment of the airfoil includes shelf hole centerlines of the holes passing through pierce points in the shelf. At least a majority of the shelf hole centerlines are angled in outboard directions away from and outboard of the squealer tip wall. A majority of centerlines are angled away from vertical lines passing through the pierce points at first component angles in a range between 2 degrees and 16 degrees.
Gas Distributor For Vapor Coating Method And Container

US Classification:
427250, 427251, 427252, 427253, 4272481
Abstract:
A method for introducing an inert carrier gas into a coating container used to provide a metallic coating on articles. The method includes introducing the inert carrier gas into the coating container as a plurality of carrier gas streams proximate the top of the coating container. The carrier gas streams are formed and introduced into the coating container before encountering a source material for the metallic coating, and each carrier gas stream is introduced so that the inert carrier gas at least initially moves within the coating container in a circular swirling fashion above and before encountering the source material and the article.

US Classification:
428557, 428553, 428570, 428680, 2282481
Abstract:
A nickel-base braze material suitable for closing holes in a high temperature component, such as a tip cap hole in a turbine blade. The braze material comprises first and second filler materials and a binder. The first filler material comprises particles of a first alloy, and the second filler material comprises particles of at least a second alloy having a lower melting temperature than the first alloy. The second alloy consists essentially of, by weight, about 8 to about 23 percent chromium, about 4 to about 18 percent cobalt, about 1. 5 to about 6. 0 percent tantalum, about 1. 0 to about 6. 0 percent aluminum, about 0. 3 to about 1. 5 percent boron, about 2. 0 to about 6. 0 percent silicon, up to 0. 2 percent carbon, the balance being nickel and incidental impurities.
