Patent number: 6905728Abstract: A new method for repairing turbine engine components is provided. The method utilizes a cold gas-dynamic spray technique to repair degradation on turbine blades, vanes and other components. In the cold gas-dynamic spray process particles at a temperature below their fusing temperature are accelerated and directed to a target surface on the turbine blade. When the particles strike the target surface, the kinetic energy of the particles is converted into plastic deformation of the particle, causing the particle to form a strong bond with the target surface. Post-spray processing is then performed to consolidate and homogenize the applied materials and restore integrity to the material properties in the repaired turbine component. Thus, the cold gas-dynamic spray process and post-spray processing can be employed to effectively repair degraded areas on gas turbine components.Type: GrantFiled: March 22, 2004Date of Patent: June 14, 2005Assignee: Honeywell International, Inc.Inventors: Yiping Hu, Murali Madhava, Federico Renteria

Patent number: 6881439Abstract: An aluminiding process that enables the cooling holes of an air-cooled component, such as a hot gas path component of a gas turbine engine, to be machined and then aluminized after all external surface coatings have been deposited. The aluminide coating is deposited using a slurry process capable of forming the aluminide coating on the component without damaging an existing ceramic coating on the component. The process involves applying an activator-free slurry containing aluminum particles that, when the component is sufficiently heated, melt and diffuse into the component surface to form the diffusion aluminide coating.Type: GrantFiled: December 4, 2002Date of Patent: April 19, 2005Assignee: General Electric CompanyInventors: Stephen Daniel Graham, John Herbert Wood, Cyril Gerard Beck, Warren Tan King

Patent number: 6862862Abstract: A method is presented for extending the lives of existing slate, fibrous cement and clay tile roofs. The method involves injecting an especially formulated, polymer material into the spaces and voids of adjoining tiles. The injection process uses pumping equipment with a custom-designed gasket at the spray gun's point of application to aid in directing the grout into the spaces and voids.Type: GrantFiled: October 7, 2002Date of Patent: March 8, 2005Inventor: Stanley P. Ward

Patent number: 6858260Abstract: A radiation curable, flexible, paintable composition produced from epoxy compounds and one or more polyol(s) has enhanced durability, thick and thin film adhesion, resistance to mold growth and dimensional changes while reducing solvent emissions. The composition can reduce, if not eliminate, runs and drips during the thermal bake cycles which are associated with using conventional compositions in automotive applications.Type: GrantFiled: March 6, 2002Date of Patent: February 22, 2005Assignee: Denovus LLCInventors: Donald W. Taylor, Todd W. Scrivens, Laurie Denise Lovshe, Jeffrey T. Pachl

Patent number: 6838177Abstract: There is disclosed a process of priming a surface (preferably part of a vehicle) comprising; i) applying a UV radiation curable primer to the area to be primed; ii) curing the primer with UV radiation provided by one or more UV lamps having a UV-B:UV-A ratio of 1:1 or less and substantially no UV-C content, the UV radiation curable primer containing: A. 0-84% by weight of one or more compounds containing one ethylenically unsaturated free-radically polymerisable group per molecule; B. 5-50% by weight of one or more compounds containing two or more ethylenically unsaturated free radically polymerisable groups per molecule; C. 10-70% by weight of one or more pigments, fillers and/or dyes; D. 1-8% by weight of one or more photoinitiators; E. 0-20% by weight of volatile organic solvent and; F. 0-15% by weight of customary additives. Preferably the process also includes sanding the primer and topcoating the primer with one or more topcoats.Type: GrantFiled: February 27, 2001Date of Patent: January 4, 2005Assignee: PPG Industries Ohio, Inc.Inventors: David Robert Fenn, Iain W. Harvey, Henryk Skorupski, David N. Walters

Publication number: 20040247781Abstract: A system is provided for touching up a chipped and scratched painted surface by applying a solvent solution to the surface, applying a selected touch-up paint, and removing a portion of the applied touch-up paint from the painted surface. The removing step includes applying a wax and solvent mixture (e.g., about 40% wax and about 60% naphtha) and then removing a residue of wax and paint by substantially immediately wiping the painted surface with a cloth. The solvent solution may include naphtha. The touch-up paint may have a tone substantially the same as the tone of the painted surface and is slightly darker than the painted surface.Type: ApplicationFiled: April 26, 2004Publication date: December 9, 2004Inventors: Kirby Doyle, Michael Doyle

Patent number: 6827969Abstract: A chemical composition and method for repairing a thermal barrier coating on a component designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The method repairs a thermal barrier coating on a component that has suffered localized damage to the thermal barrier coating. After cleaning the surface area of the component exposed by the localized spallation, a mixture of a ceramic composition comprising a ceramic powder in a binder is applied, preferably by spraying, to the surface area of the component. The binder is then allowed to dry to form a dried coating. Upon subsequent heating, the dried coating reacts to produce a ceramic-containing repair coating, wherein the coating comprises the ceramic powder in a matrix of a material formed when the binder was reacted. The binder is preferably a ceramic precursor material that can be converted immediately to a ceramic or allowed to thermally decompose over time to form a ceramic.Type: GrantFiled: December 12, 2003Date of Patent: December 7, 2004Assignee: General Electric CompanyInventors: Andrew Jay Skoog, Jane Ann Murphy, William Randolph Stowell, Timothy Ray Lattire

Publication number: 20040219290Abstract: A method applying a thermal barrier coating to a metal substrate, or for repairing a thermal barrier coating previously applied by physical vapor deposition to an underlying aluminide diffusion coating that overlays the metal substrate. The aluminide diffusion coating is treated to make it more receptive to adherence of a plasma spray-applied overlay alloy bond coat layer. An overlay alloy bond coat material is then plasma sprayed on the treated aluminide diffusion coating to form an overlay alloy bond coat layer. A ceramic thermal barrier coating material is plasma sprayed on the overlay alloy bond coat layer to form the thermal barrier coating. In the repair embodiment of this method, the physical vapor deposition-applied thermal barrier coating is initially removed from the underlying aluminide diffusion coating.Type: ApplicationFiled: April 30, 2003Publication date: November 4, 2004Inventors: Bangalore Aswatha Nagaraj, Eva Zielonka Lanman, Deborah Anne Schorr, Thomas John Tomlinson, Raymond William Heidorn, David Allen Kastrup, Craig Douglas Young
