Patent number: 6695587Abstract: A gas turbine component article has an airfoil section and is formed of a nickel-base superalloy. An unmasked region of the airfoil section has a platinum aluminide protective coating, and a masked region of the airfoil section has an aluminide coating. The platinum aluminide preferably is deposited at a trailing edge of the airfoil section that is susceptible to low-cycle fatigue damage when a platinum aluminide coating is present.Type: GrantFiled: May 6, 2002Date of Patent: February 24, 2004Assignee: General Electric CompanyInventors: Roger D. Wustman, Antonio F. Maricocchi, Jonathan P. Clarke

Patent number: 6485845Abstract: A thermal barrier coating (TBC) system and method for forming the TBC system on a component designed for use in a hostile thermal environment, such as superalloy turbine, combustor and augmentor components of a gas turbine engine. The TBC system exhibits improved spallation resistance as a result of having a bond coat formed to contain a dispersion of oxide particles in its outer surface region. A method for preferentially entrapping oxide particles in a bond coat entails depositing the oxide particles on the surface of the component prior to forming the bond coat, which may be a diffusion aluminide or an aluminized overlay coating. Deposition of the bond coat causes the oxide particles to become dispersed in the outer surface region of the bond coat. A particular feature of this invention is the ability to preferentially entrap oxides of elements that are not present in the bond coat or a substrate region of the component on which the bond coat is formed.Type: GrantFiled: January 24, 2000Date of Patent: November 26, 2002Assignee: General Electric CompanyInventors: Roger D. Wustman, Jeffrey A. Conner, Jonathan P. Clarke, Timothy L. Norris, William E. Brummett, II, Thomas E. Mantkowski

Patent number: 6364608Abstract: An article comprising an airfoil surface is provided with a thermal insulating outer layer on at least one region, but not all, of the airfoil surface. The region is selected from the airfoil surface which has been observed to experience more strenuous environmental operating conditions during service operation than the airfoil surface outside of the region. In one form, the thermal insulating outer layer is applied to at least one region of each of a plurality of airfoil surfaces. Each airfoil surface is disposed about an axis of rotation with the region of each airfoil surface facing generally outwardly from the axis of rotation and from each other. The airfoil surfaces are rotated about the axis of rotation while a thermal insulating material contacts at least the regions.Type: GrantFiled: June 16, 2000Date of Patent: April 2, 2002Assignee: General Electric CompanyInventors: Gulcharan S. Brainch, Michael J. Danowski, Roger D. Wustman, Jonathan P. Clarke

Patent number: 6276597Abstract: A tip cap hole is loaded with a first composition comprising particles of a first alloy having a solidus temperature above the brazing temperature. The first composition is covered with a second composition comprising particles of a second alloy having a liquidus temperature below the brazing temperature. The second composition is heated to the brazing temperature to cause particles of the second alloy to melt to form a liquid of the second alloy which is carried into spaces between the particles of the first alloy by capillarity. The liquid of the second alloy is cooled to form a solid securely bonding the particles of the first alloy. By weight, the second alloy has no more than 1% B and from 3% to 11% Si. The first alloy has Cr and at least about 5% Al, at least about 0.5% Hf, no more than 0.5% Ti.Type: GrantFiled: September 20, 2000Date of Patent: August 21, 2001Assignee: General Electric CompnayInventors: David E. Budinger, Ronald L. Galley, Roger D. Wustman, Jonathan P. Clarke

Patent number: 6274215Abstract: An article having a design external aerodynamic shape includes a body with a body external surface and an outer portion external surface of an outer portion bonded with a part of but less than substantially all of the body surface. The external surfaces of the body and outer portion each define less than the design external aerodynamic shape. However, together they define such shape. The article is made by selecting the design external aerodynamic shape from an existing article having a first body and a first outer portion. A replacement outer portion is selected in an amount less than the first outer portion and bonded with a region less than substantially all of a replacement body external surface. The replacement body has a replacement body external surface and replacement body external shape different from the first body substantially by that amount. The replacement body is made with the replacement body external shape.Type: GrantFiled: December 21, 1998Date of Patent: August 14, 2001Assignee: General Electric CompanyInventors: Gulcharan S. Brainch, Michael J. Danowski, Jonathan P. Clarke

Patent number: 6254756Abstract: A curved component such as a turbine airfoil, shroud, or combustor centerbody is prepared with a platinum or a platinum-aluminide protective coating over only a portion of the surface thereof. The coating may serve as an environmental coating, or as a bond coat of a thermal barrier coating system. The partial coverage is achieved by depositing platinum only over a portion of the surface of the component, typically including the concave portion in the case of an airfoil, optionally depositing an aluminum layer, and optionally interdiffusing the platinum and aluminum layers.Type: GrantFiled: August 11, 1999Date of Patent: July 3, 2001Assignee: General Electric CompanyInventors: Antonio F. Maricocchi, Roger D. Wustman, Jonathan P. Clarke, Thomas E. Mantkowski, David G. W. Fargher, Jeffrey A. Conner
