| 20090178736 | ARTICLE HAVING COBALT-PHOSPHOROUS COATING AND METHOD FOR HEAT TREATING - A method of processing an article having a substrate and a cobalt-phosphorous coating disposed on the substrate includes heat treating the article. At least one physical characteristic of the cobalt-phosphorous coating is altered using the heat treating to thereby change a performance characteristic of the article. For example, the article may be an actuator component having a bore or a shaft that is movably disposed at least partially within the bore. | 07-16-2009 |
| 20100014964 | ELECTRO-FORMED SHEATH FOR USE ON AIRFOIL COMPONENTS - An article for protecting an airfoil component includes a sheath having an outer side and an inner side that forms a cavity for receiving a leading edge of the airfoil component. The sheath is made of cobalt and phosphorous to protect the leading edge of the airfoil component from erosion. | 01-21-2010 |
| 20100028713 | METHOD AND ARTICLE FOR IMPROVED ADHESION OF FATIGUE-PRONE COMPONENTS - A method of processing an article includes mechanically working an article having a metallic layer disposed on a titanium substrate and establishing a residual stress region that extends through the metallic layer and at least partially into the titanium substrate. | 02-04-2010 |
| 20100147694 | METHOD AND APPARATUS FOR EVALUATION OF COATED PARTS - A method of verifying performance of a coated part includes calculating a deflection value as a function of a predetermined strain threshold value and a total thickness of a test coupon that comprises a coating on a substrate. The coating of the test coupon is co-deposited in a deposition process for producing a coated part. The test coupon is bent in an amount equal to the calculated deflection value and then evaluated as an indication of whether a mechanical characteristic of the coated part meets a specified level. | 06-17-2010 |
| 20100304107 | LAYERED COATING FOR EROSION PROTECTION - A coating for protecting a surface against erosion when contacted by particles having a range of particle sizes or by high velocity fluid impingement includes a first coating on the surface forming a high bulk or composite hardness coating; and a hard ceramic coating on the first coating having a hardness higher than the hardness of the first coating and the erosion particles. | 12-02-2010 |
| 20110073217 | WEAR RESISTANT DEVICE AND PROCESS THEREFOR - A wear resistant device includes a substrate of a first metallic material and a wear resistant layer disposed on a substrate. The wear resistant layer includes a matrix of a second, different metallic material, particulates dispersed throughout the matrix, and a boron material dispersed within a portion of the matrix. | 03-31-2011 |
| 20110114495 | LOW COST, ENVIRONMENTALLY FAVORABLE, CHROMIUM PLATE REPLACEMENT COATING FOR IMPROVED WEAR PERFORMANCE - A coating which improves the wear performance of a part is described. The coating is applied over an article such as a part or a workpiece using an electroplating process. The coating broadly includes a cobalt material matrix with a hardness of at least 550 HV and a plurality of carbide particles distributed throughout the cobalt material matrix. The cobalt material matrix may be a cobalt-phosphorous alloy. The particles interspersed throughout the matrix may be chrome carbide or silicon carbide particles. | 05-19-2011 |
| 20110116906 | AIRFOIL COMPONENT WEAR INDICATOR - An example airfoil assembly includes an airfoil body extending between a leading edge, a trailing edge, a suction side, and a pressure side. The assembly further includes a first protective sheath, an indicator sheath, and a second protective sheath. The first protective sheath has an outer side and an inner side that forms a cavity for receiving at least a portion of the airfoil body. The inner side being bonded to the leading edge of the airfoil body. A portion of the indicator sheath is positioned forward the first sheath relative to the leading edge of the airfoil. A portion of the second protective sheath is positioned forward the indicator sheath relative to the leading edge of the airfoil. | 05-19-2011 |
