| 20090094829 | Method for ultrasonic peening of gas turbine engine components without engine disassembly - A method for peening a component of a gas turbine engine, or a module of a gas turbine engine, without removing the component from the assembled gas turbine engine or module includes blending the damaged area of the component, determining parameters for peening the damaged component, and peening the damaged component without removing it from the engine. | 04-16-2009 |
| 20090250441 | Bolt hole repair technique - A method of hole defect repair includes removing one or more defects at or near a desired hole in a part by removing a portion of the part proximate the desired hole in a series of chain link patterns, and welding a filler material to the part after removing the chain link pattern portion of the part. | 10-08-2009 |
| 20090269208 | REPAIR METHOD AND REPAIRED ARTICLE - A method of repairing an article includes removing an undesirable section of the article, attaching a repair section to the article at a location from which the undesirable section has been removed, and mechanically working the repair section to achieve a reduction in a cross-sectional area of the repair section. | 10-29-2009 |
| 20090271984 | METHOD FOR REPAIRING A GAS TURBINE ENGINE COMPONENT - A method of repairing a stator assembly of a gas turbine engine includes removing a worn surface of the stator assembly to provide a revealed area, and securing additional material to the stator assembly utilizing gas metal arc welding. | 11-05-2009 |
| 20100032415 | Repair Methods Involving Conductive Heat Resistance Welding - Repair methods involving conductive heat resistance welding includes repairing a crack of a gas turbine engine component using a conductive heat resistance welding technique and a welding technique other than conductive heat resistance welding. | 02-11-2010 |
| 20100096368 | Deposition apparatus and methods - Microspray apparatus and methods involve injecting powdered material into a plasma gas stream. The material comprises first and second component powders. The second powder is a majority by the weight of the powdered material. The first powder acts as a melting point depressant. The first and second powders may have similar compositions but with the first powder including a greater quantity of a melting point depressant element. | 04-22-2010 |
| 20100119375 | Pre-Coating Burnishing of Erosion Coated Parts - A gas turbine engine blade has a platform. A root depends from the platform and an airfoil extends from the platform. The airfoil has leading and trailing edges and pressure and suction sides. The blade has a substrate having a surface. A compressive stress exists below a first region of the surface. The first region extends over a majority of a streamwise perimeter of the airfoil at a location at a spanwise distance from the tip or more than 50% of a tip-to-platform span. A coating is on the surface including at the location. | 05-13-2010 |
| 20100285330 | Vapor Deposition of Dissimilar Materials - A method for depositing a first material on a substrate includes providing the substrate in a deposition chamber. A molten body is formed between the substrate and a source of the first material by melting one or more second materials. A flow of the first material is passed through the molten body and from the molten body to the substrate as a vapor flow. An essentially non-expending portion of the molten body comprises an alloy having a melting temperature below a melting temperature of the first material. | 11-11-2010 |
