| 20100104766 | METHOD FOR USE WITH A COATING PROCESS - A method for use with a coating process includes depositing a ceramic coating on a substrate within a coating chamber. Prior to depositing the ceramic coating, an electron beam source is used to heat a ceramic material. The ceramic material radiates heat to heat a substrate to an oxidation temperature to form an oxide layer on the substrate. A desired evaporation rate of the ceramic material is established during the heating to thereby provide an improved ceramic coating. | 04-29-2010 |
| 20100104773 | METHOD FOR USE IN A COATING PROCESS - A method for use in a coating process includes depositing a ceramic coating on a bond coat that is disposed on a substrate. Prior to depositing the ceramic coating, a desired surface roughness R | 04-29-2010 |
| 20100189929 | COATING DEVICE AND DEPOSITION APPARATUS - A coating device for use with an electron beam vapor deposition apparatus includes a crucible portion and a nozzle portion. The crucible portion includes a gas inlet port, a heating zone for presenting a source coating material to be heated, and a flow passage exposed to the heating zone and fluidly connected with the inlet port. The nozzle portion of the coating device includes an outlet orifice fluidly connected with the flow passage for jetting a coating stream from the coating device. | 07-29-2010 |
| 20100242841 | ELECTRON BEAM VAPOR DEPOSITION APPARATUS AND METHOD OF COATING - An electron beam vapor deposition apparatus includes a coating chamber including a coating zone for depositing a coating on a work piece. A coating device includes at least one crucible for presenting at least one source coating material. The coating device includes a first deposition mode of depositing the at least one source coating material and a second deposition mode of depositing the at least one source coating material. At least one electron beam source evaporates the at least one source coating material for deposit onto the work piece. A controller is configured to control a speed of movement of the work piece in the coating zone during the coating operation in response to the first deposition mode and the second deposition mode. | 09-30-2010 |
| 20100247809 | ELECTRON BEAM VAPOR DEPOSITION APPARATUS FOR DEPOSITING MULTI-LAYER COATING - A physical vapor deposition apparatus includes first and second chambers. A first directed vapor deposition crucible is at least partially within the first chamber for presenting a first source material to be deposited on a work piece. A second directed vapor deposition crucible is at least partially within the second chamber for presenting a second, different source material to be deposited as a second coating on the work piece. At least one of the materials may be deposited as a coating. | 09-30-2010 |
| 20100247952 | CONTROLLED OXIDATION OF BOND COAT - A method of processing an article includes heating the article in an atmosphere substantially free of oxygen to an oxidation temperature within a predetermined temperature range. The article includes a substrate and a bond coat disposed on the substrate. A partial pressure of oxygen is then established within the atmosphere after heating to the oxidation temperature. At least a portion of the bond coat oxidizes in the partial pressure of oxygen at the oxidation temperature to form a desired type of oxide to the substantial exclusion of forming other types of oxides. A ceramic coating is then deposited on the oxide. | 09-30-2010 |
| 20100263590 | Vapor Deposition Electron Beam Current Control - Systems and methods are described that monitor electron beam current and voltage. The systems and methods react to fault conditions such as arcing experienced during evaporation and deposition processes to shutdown and protect associated power supply equipment. The systems and methods may provide online beam current control to provide stable operation of e-beam guns during heating and melting modes of operation. | 10-21-2010 |
| 20110135895 | ARTICLE HAVING THERMAL BARRIER COATING - An article includes a metallic substrate and a tri-layer thermal barrier coating that is deposited on the metallic substrate. The tri-layer thermal barrier coating includes an inner ceramic layer, an outermost ceramic layer relative to the metallic substrate, and an intermediate ceramic layer between the inner ceramic layer and the outermost ceramic layer. The inner ceramic layer and the outermost ceramic layer are composed of respective first and second ceramic materials and the intermediate ceramic layers composed of a third, different ceramic material. The inner ceramic layer has a first thickness, the outermost ceramic layer has a second thickness, and the intermediate ceramic layer has a third thickness that is greater than the first thickness and the second thickness. | 06-09-2011 |
