Patent application number | Description | Published |
20090095435 | MACHINING OF PARTS HAVING HOLES - Removing of a casting core from a metal casting leaves at least one opening in a surface of the metal. The opening is filled with a sacrificial material. The metal and sacrificial material are machined at the opening. After the machining, a remainder of the sacrificial material is removed. | 04-16-2009 |
20100155251 | HARD ANODIZE OF COLD SPRAY ALUMINUM LAYER - A process for repairing components includes the steps of providing a component having an affected area on a surface of a component to be repaired; depositing a repair material over the affected area on the surface of the component so that the repair material plastically deforms without melting and bonds to the affected area upon impact with the affected area and thereby covers the affected area; providing a sulfuric acid based anodizing solution; anodizing a deposited repair material on the surface of said component in the sulfuric acid based anodizing solution; consuming only a portion of the deposited repair material to form a hard anodized coating layer upon the deposited repair material to form a hard anodized coated component; providing a corrosion resistant sealant solution; and contacting a hard anodized coated component with the corrosion resistant sealant solution to form a corrosion resistant sealant coating on the hard anodized coated component. | 06-24-2010 |
20100219325 | METALLIC COATED CORES TO FACILITATE THIN WALL CASTING - A core for investment casting processes includes a core comprising one or more ceramic materials; and an exterior layer of metal material not susceptible to oxidation under investment casting operating conditions. A method for casting a turbine engine component having an internal passageway includes the steps of forming one or more mold sections each having internal surfaces and at least one of the aforementioned cores for forming one or more turbine engine components having at least one internal passageway; assembling the one or more mold sections; introducing a molten alloy into the one or more assembled mold sections; and consuming the metal of the at least one core during the process. | 09-02-2010 |
20100260613 | Process for preventing the formation of secondary reaction zone in susceptible articles, and articles manufactured using same - A process for reducing secondary reaction zone formation articles includes the steps of non-selective removing an external surface of an as-cast article free of coating to form an as-cast article having a surface substantially free of residual surface stress; and applying a coating material upon the surface substantially free of residual surface stress to form a coated as-cast article having a coating layer disposed upon the surface substantially free of residual surface stress. | 10-14-2010 |
20100266392 | ABRASIVE THERMAL COATING - A protective coating for a surface exposed to hot gas flow comprises a thermal layer, a conducting layer and an abrasive layer. The thermal layer comprises stabilized zirconia, and overlies the surface. The conducting layer overlies the thermal layer. The abrasive layer comprises abrasive particles bonded in a metal matrix that is electroplated onto the conducting layer. | 10-21-2010 |
20100276103 | Metallic Coated Cores to Facilitate Thin Wall Casting - A core for investment casting processes includes a core having one or more ceramic materials; and an exterior layer of metal material not susceptible to oxidation under investment casting operating conditions. A method for casting a turbine engine component having an internal passageway includes the steps of forming one or more mold sections each having internal surfaces and at least one of the aforementioned cores for forming one or more turbine engine components having at least one internal passageway; assembling the one or more mold sections; introducing a molten alloy into the one or more assembled mold sections; and consuming the metal of the at least one core during the process. | 11-04-2010 |
