20080220165 | Gas Turbine Engine Components With Aluminide Coatings And Method Of Forming Such Aluminide Coatings On Gas Turbine Engine Components - A turbine engine component ( | 09-11-2008 |
20080245302 | SIMPLE CHEMICAL VAPOR DEPOSITION SYSTEMS FOR DEPOSITING MULTIPLE-METAL ALUMINIDE COATINGS - A chemical vapor deposition (CVD) system and method for applying an aluminide coating constituted by two or more extrinsic metal components on a jet engine component. The aluminide coating is capable of forming a protective complex oxide upon subsequent heating in an oxidizing environment. At least one of the extrinsic metals in the aluminide coating is provided as a first vapor phase reactant from a receptacle coupled by a closed communication path with the reaction chamber of the CVD system and free of a carrier gas. The aluminide coating is formed by the chemical combination of the first vapor phase reactant with a second vapor phase reactant either created in situ in the reaction chamber or supplied by a carrier gas to the reaction chamber from a precursor source. | 10-09-2008 |

20090120804 | APPARATUS, METHODS, AND COMPOSITIONS FOR REMOVING COATINGS FROM A METAL COMPONENT - Apparatus and methods for removing coatings from metal components, such as metal components used in aircraft and other aerospace vehicles and the oil industry, as well as aqueous bath compositions. The metal component may be DC coupled with a counter electrode and immersed in an aqueous bath that includes an active oxygen source and a ligand in a composition effective to remove the coating. The aqueous bath may include hydrogen peroxide as the active oxygen source and may be maintained in a specific pH range if the temperature of the aqueous bath is controlled. In an alternative embodiment, the composition of the aqueous bath may include a non-peroxide active oxygen source, such as sodium perborate, and be maintained in a different specific pH range. An oxygen sensor may be provided to periodically monitor the concentration of active oxygen in the aqueous bath. | 05-14-2009 |

20120141671 | ROUGHENED COATINGS FOR GAS TURBINE ENGINE COMPONENTS - A gas turbine engine component with an aluminide coating on at least a portion of an airflow surface that includes a roughening agent effective to provide a desired surface roughness and a deposition process for forming such aluminide coatings. A layer including a binder and the roughening agent may be applied to the superalloy substrate of the component and the aluminide coating formed on the airflow surface portion by exposing the component and layer to an appropriate deposition environment. Suitable roughening agents include metal and ceramic particles that are dispersed on the airflow surface portion before exposure to the deposition environment. The particles, which are substantially intact after the aluminide coating is formed, are dispersed in an effective number to supply the desired surface roughness. | 06-07-2012 |
20130059084 | Chemical Vapor Deposition of Metal Layers for Improved Brazing - A method of forming a metallic wetting layer on the surface of a metal component is provided, including the steps of placing the component into a chemical vapor deposition furnace, placing a metal-containing salt in the furnace, and heating the component and the metal-containing salt in the furnace to cause the metal from the metal-containing salt to deposit in a coating on the surface of the component forming a metallic wetting layer that improves the metallic bond of a subsequently applied brazing material. The process can be practiced with the addition of a cleaning reagent to both clean and coat in one operation. | 03-07-2013 |
20140120266 | METAL COMPONENTS WITH SILICON-CONTAINING PROTECTIVE COATINGS SUBSTANTIALLY FREE OF CHROMIUM AND METHODS OF FORMING SUCH PROTECTIVE COATINGS - Metal components with a protective coating containing silicon and a process for forming such protective coatings. The protective coating is formed by applying a silicon-containing fluid composition to the metal component as a silicon-containing layer and then heating the silicon-containing layer to a temperature exceeding 400° F. | 05-01-2014 |
