6485655, Nov 26, 2002
Filed:
Aug 2, 2001
Appl. No.:
09/921501
Inventors:
Nripendra Nath Das - West Chester OH
Stephen Joseph Ferrigno - Cincinnati OH
Jim Dean Reeves - Cincinnati OH

International Classification:
B32B 3500
US Classification:
216 45, 216 51, 156344, 15634519, 1563453, 156 29, 1564026
Abstract:
An internal coating on an internal passage wall exposed at a passage opening through an article external surface is protected from removal during repair of the article, including removal of at least a portion of an external coating, by a masking assembly disposed about the passage opening. The masking assembly comprises a masking member and a substantially flexible seal, substantially inert to a coating removal medium for the external coating. The masking member is shaped for disposition about the passage opening across a gap between the external surface and the masking member. The substantially flexible seal is disposed across the gap substantially to seal the gap.

Method Of Cleaning Turbine Component Using Laser Shock Peening

US Patent:
6500269, Dec 31, 2002
Filed:
Jan 29, 2001
Appl. No.:
09/771850
Inventors:
James D. Risbeck - Cincinnati OH
Thomas E. Anderson - Mason OH
Stephen J. Ferrigno - Cincinnati OH

Assignee:
General Electric Company - Schnectady NY
International Classification:
B08B 312
US Classification:
134 1, 134 221, 134 2211, 134 2212, 134 2218, 134 26, 134 30
Abstract:
A method of cleaning airfoils and related turbine engine components that have a crust-like debris deposited on the surface thereof. This method involves subjecting at least the portion of the component having the deposit of the crust-like debris to sufficient laser shock peening to cause the debris on the surface thereof to be loosened therefrom so that the loosened debris can be removed from the component. This loosened debris can then be removed from the component, such as by passing a cleaning fluid through the portion of the component that is subjected to the laser shock peening.

Method And Apparatus For Selectively Removing Coatings From Substrates

View page
US Patent:
6599416, Jul 29, 2003
Filed:
Sep 28, 2001
Appl. No.:
09/682620
Inventors:
Lawrence Bernard Kool - Clifton Park NY
Bin Wei - Mechanicville NY
James Anthony Ruud - Delmar NY
Mark Alan Rosenzweig - Hamilton OH
Stephen Joseph Ferrigno - Cincinnati OH
Assignee:
General Electric Company - Niskayuna NY
International Classification:
C25F 500
US Classification:
205717, 205722, 205723, 204224 M, 204267, 204272
Abstract:
An electrochemical stripping method for selectively removing at least one coating from the surface of a substrate is described. The substrate is immersed in an aqueous composition through which electrical current flows. The composition includes an acid having the formula H AF , in which âAâ is Si, Ge, Ti, Zr, Al, or Ga; and x is 1-6. Various coatings can be removed, such as diffusion or overlay coatings. The method can be used to fully-strip a coating (e. g. , from a turbine component), or to partially strip one sublayer of the coating. Related processes and an apparatus are also described.

Foil Formed Structure For Turbine Airfoil Tip

View page
US Patent:
6634860, Oct 21, 2003
Filed:
Dec 20, 2001
Appl. No.:
10/028107
Inventors:
Melvin Robert Jackson - Niskayuna NY
Stephen Joseph Ferrigno - Cincinnati OH
Assignee:
General Electric Company - Schenectady NY
International Classification:
F01D 518
US Classification:
416 97R, 416241 R, 416224
Abstract:
A turbine airfoil is provided having an integral tip cap and a pair of tip walls which extend radially outward past the tip cap to form a squealer tip. A coaxial pair of first and second holes extend through the tip cap and one of the tip walls respectively at an acute inclination angle, with the first hole being disposed so as to direct impingement cooling air on the tip wall having the second hole. A protective layer comprising a high temperature foil is disposed on the tip wall having the second hole therein.

F01D 514
B64C 1116
US Classification:
428670, 428666, 428669, 428652, 416241 R
Abstract:
A protected article includes a nickel-base superalloy substrate, an interlayer overlying the substrate, and a protective layer overlying the interlayer. The protective layer has a composition comprising at least one of rhodium, platinum, palladium, and ruthenium. In one composition, palladium is present in an amount of from about 1 to about 41 atomic percent; platinum is present in an amount of about (40+atomic percent palladium) atomic percent for palladium ranging from about 1 atomic percent to about 14 atomic percent and up to about 54 atomic percent for palladium ranging from about 15 atomic percent up to about 41 atomic percent; rhodium is present in an amount of at least about 24 atomic percent; zirconium, hafnium, titanium, and mixtures thereof are present in an amount of from zero up to about 5 atomic percent; and ruthenium is present in an amount of from zero up to about 5 atomic percent, balance impurities. The interlayer has a coefficient of thermal expansion intermediate between that of the substrate and that of the protective layer. The protected article is fabricated by furnishing the substrate, applying the interlayer over the substrate, and applying the protective layer over the interlayer.
