20090051915 | Arrangement for Monitoring Thermal Spray Processes - An arrangement for measuring characteristic properties of a plasma beam in a thermal spray process, including a device for introducing spray materials into the plasma, a one-dimensional or two-dimensional array including first optical waveguides for receiving the light radiation emitted by the plasma, and other optical waveguides for distributing the light radiation emitted by the plasma. A device is provided for splitting the light guided in the first optical waveguides into the other optical wave guides, one optical waveguide being connected to the opening diaphragm of a particle flow arrangement, and the other optical waveguide being connected to the opening diaphragm of a spectrometer. A device is also provided for determining the current state of the spray process. | 02-26-2009 |
20100062172 | METHOD FOR THE PRODUCTION OF AN ABRADABLE SPRAY COATING - A method for producing a spray coating, in particular an abradable spray coating for components of a turbine engine by a thermal spraying process, is disclosed. An online process monitoring system, especially a PFI unit and/or a spectrometer unit, is provided for monitoring and regulating the thermal spraying process, where at least one process parameter is calculated according to the formula p | 03-11-2010 |
20100166944 | METHOD FOR DETERMINING THE POLYESTER FRACTION OF A MULTI-COMPONENT POWDER DURING A THERMAL SPRAYING PROCESS, METHOD FOR COATING OR TOUCHING UP AN OBJECT BY MEANS OF A THERMAL SPRAYING PROCESS AND THERMAL SPRAYING DEVICE - A method for determining the polyester fraction in a multi-component powder during a thermal spraying process is disclosed. The multi-component powder is heated and fed to an object with the aid of a carrier, forming a coating on the object. At least one measured value for the intensity of the light emitted by the combination of the carrier and multi-component powder material on the way to the object is detected at least in the range of a characteristic wavelength of polyester. A characteristic value is derived from the combination of the measured values, and the fraction of the polyester to be determined is calculated on the basis of a previously determined relationship between the characteristic value and the polyester fraction. | 07-01-2010 |
20110070369 | COVERING DEVICE AND METHOD FOR COATING COMPONENTS - A covering device for the coating of components via cold kinetic compaction or kinetic cold gas spraying, which can be used to cover a region which is not to be coated of a surface of the component which is to be coated. The covering device is profiled such that it encloses an acute angle with that region of the surface which is not to be coated. The particles of a coating material can be deflected from the component such that the particles do not adhere to the covering device. | 03-24-2011 |
20110177250 | APPARATUS AND METHOD FOR MASKING A COMPONENT ZONE - An apparatus and a method for masking a component zone which is to be omitted by the spray jet during the thermal spraying of a component is disclosed. The apparatus can be elastically deformed at least partially at room temperature for attachment to the component. During the thermal spraying operation the apparatus has at least one inelastic region such that the impinging spray particles adhere to the surface thereof. After the thermal spraying operation, the apparatus can be removed from the covered component zone without leaving any residue. In this way, a simple, reusable solution is created, which avoids the disadvantages of the prior art. | 07-21-2011 |
20110223325 | MASK FOR KINETIC COLD GAS COMPACTING - A mask and method for kinetic cold gas compacting is disclosed. The mask includes a body for covering a not-to-be-coated region of a substrate to be coated having a work side exposed to a coating substance. The work side has a hardness such that the work side is not plastic deformable by a striking coating particle. | 09-15-2011 |
20120225213 | METHOD AND DEVICE FOR COATING COMPONENTS - A method for spraying a coating and a cold gas spray nozzle is disclosed. The method includes spraying a coating by the cold gas spray nozzle. A rinsing gas is fed to the cold gas spray nozzle during an interruption of the spraying or at an end of the spraying. Deposits in the cold gas spray nozzle are cooled and detached by the rinsing gas. | 09-06-2012 |

20130034661 | METHOD FOR PROCESSING A SURFACE OF A COMPONENT - A method for processing a surface of a component, in particular in the aviation sector, including the following steps: spraying the component with a first powder and coating the component with a second powder, the first powder having the same chemical composition as the second powder. | 02-07-2013 |
20130129976 | COATING PLASTIC COMPONENTS BY MEANS OF KINETIC COLD GAS SPRAYING - A method for coating a plastic surface and a plastic component is disclosed. The method includes applying a base layer to a plastic surface. A layer of a coating is applied by kinetic cold gas spraying on the base layer. The base layer is applied by a method that is different from the kinetic cold gas spraying. The base layer adheres to the plastic surface and the layer of the coating applied by kinetic cold gas spraying is deposited on the base layer by the kinetic cold gas spraying. | 05-23-2013 |
