20090315573 | Component with a detection structure for mechanical damage - A component made of electrically insulating material with a detection structure for mechanical damage such as cracks is disclosed. The detection structure is a conductor. The electrical properties of the detection structure are modified as more and more cracks are formed such that the component will be replaced in time before breaking. The electrical conductor is formed by particles that are in contact with each other and have a metallic surface such that an electrical conductor is created which is particularly sensitive to mechanical damage, thus rendering the detection structure highly sensitive. Furthermore, if the metallic surface is produced merely by cladding the particles while the inside of the particles is made of the same material as the component, a conductor featuring an adapted thermal expansion behavior is created for components that are subject to great thermal stress, e.g. heat shield panels. | 12-24-2009 |
20100079974 | APPARATUS FOR THE OPTICAL INSPECTION OF THE THERMAL PROTECTION TILES OF A SPACE SHUTTLE - An apparatus for the inspection of the heat shield of a space shuttle has a drive so that it can automatically undertake an examination of the tiles of the heat shield. The apparatus moves over the surface with the aid of the drive, and images of the region to be inspected are produced with the aid of a camera. For these images, the tiles are illuminated subsequently by light sources from different directions, as a result of which the tiles can be reliably evaluated with regard to possible defects. | 04-01-2010 |
20100098845 | Method for feeding particles of a coating material into a thermal spraying process - In a method particles are delivered to a thermal spraying process for forming a layer on a component. They are entrained there by a carrier gas stream and deposited on a component to be coated. The particles are dispersed in a liquid or solid additive before being introduced into a supply line which issues into the thermal spraying apparatus, the additive, after leaving the supply line, being transferred into the gaseous state in the carrier gas stream. A liquid additive evaporates or a solid additive is sublimated, whereby the particles in the carrier gas stream are separated. The dispersal of the particles in the additive simplifies an exact metering and prevents the particles from forming lumps, so that improved layers can be deposited by virtue of an improved homogeneity of the carrier gas stream. As the additive has been transferred into the gaseous state, it is not deposited in the layer. | 04-22-2010 |

20100297345 | METHOD FOR REPAIRING A COMPONENT BY COATING - A method for repairing a component such as a turbine blade is provided. At the end of its operating time, the component has, for example, a depletion of aluminium in a region near the surface. The application of a repair layer is provided including particles with an increased proportion of aluminium. A subsequent heat treatment may achieve the effect of equalizing the concentration of aluminium between the repair layer and the region near the surface, and so the aluminium content required for new components is achieved again. | 11-25-2010 |
20110014484 | ELECTRON ABSORBER LAYER - In a method for applying an electron absorber layer to a substrate, an electron absorber layer is produced from a composite material, by coating the substrate with a metallic material, and material inclusions made from an additional material are embedded in the metallic material during coating. The metallic material contains aluminum, magnesium, cobalt, iron, chromium, titanium, nickel, copper, or an alloy or mixture thereof. The additional material contains one or more of the following substances: boron, carbon or silicon, a mixture of these elements, one or more chemical compounds made from or having at least two of these elements, or a mixture of such chemical compounds. | 01-20-2011 |
20110094439 | COLD GAS SPRAYING SYSTEM - A gas heating device is connected to a stagnation chamber having a Laval nozzle discharging a gas stream with incorporated particles at an ultrasonic speed, thus forming a cold gas spraying system capable of coating a surface by the accelerated particles. To achieve an better layer quality, at least one section of the cold gas spraying system, downstream of the gas heating device, is thermally protected by lining or forming the internal wall of the section with a ceramic insulation material having a heat conductivity of less than 20 W/Km to separate the internal wall of the section from the gas stream. A sleeve may be used, a portion of which is cylindrical and another portion which is a truncated conical section; the cylindrical section being inserted into the stagnation chamber and the conical section being inserted into the convergent subsection of the Laval nozzle. | 04-28-2011 |

20120097322 | METHOD FOR CLADDING COMPONENT WITH SELF-SUPPORTING CLADDING CLOSED BY COLD SPRAYING - Cladding that is self-supporting is joined on a component such that a joining gap is created between the edges. The joining gap is closed by cold gas spraying with a bead-like layer such that the cladding can be used, for example, as corrosion protection. If the component is made of aluminum, for example, the component can be sued as a current-conducting component during galvanic coating. In this case, a cladding made of titanium can be used as the corrosion protection layer. | 04-26-2012 |
20120180783 | CENTRAL TUBE FOR A LINEAR CONCENTRATING SOLAR THERMAL POWER PLANT, HAVING AN ABSORBER LAYER, AND METHOD FOR APPLYING SAID ABSORBER LAYER - A central tube for linear concentrating solar thermal power plants, has an absorber layer. The absorber layer is generated by cold gas sputtering, wherein suitable method parameters can in particular generate an increased surface roughness by means of pores in the surface region of the absorber layer. An absorber layer can thus be advantageously produced, having a quadratic roughness of no more than 1 μm, measured in a close range of no more than 50 μm diameter, and preferably being made of a corrosion-proof hard alloy comprising tungsten carbide, in particular WC—CoCr, WC—Co, WC—FeCo, WC—FeC, WC—FeNi, WC—Ni or WC—NiCr. | 07-19-2012 |
20120269982 | METHOD FOR ELECTROCHEMICAL COATING - In a method for coating a work piece, a layer is electrochemically produced from a first material. In order to generate an inhomogeneous expansion behavior of the layer, a thermal spraying, in particular a cold gas spraying, achieves that specific zones are created in the layer from a material having a different thermal expansion behavior. These zones expand more laterally than in the direction of the layer thickness so that directed internal stresses occur in the layer upon heating or cooling of the component, which can be specifically utilized depending on the design conditions of the component. | 10-25-2012 |
20130078450 | METHOD FOR COLD GAS SPRAYING OF A LAYER HAVING A METAL MICROSTRUCTURE PHASE AND A MICROSTRUCTURE PHASE MADE OF PLASTIC, COMPONENT HAVING SUCH A LAYER, AND USE OF SAID COMPONENT - In a method for cold gas spraying a layer, coating particles are accelerated in a cold spraying nozzle. The particles have a plastic encapsulation. In said manner, the plastic is precipitated onto the substrate together with the metal material, thereby forming in particular layer compositions having good sliding properties, dirt repellent properties, or lubricating properties. The coating can be used as a bearing component of a sliding bearing, as a flow component, in particular as a rotor blade of wind power plants or body components of transportation vehicle, or as trim components of structures. | 03-28-2013 |

20130207409 | BOGIE SHAFT FOR A RAILWAY VEHICLE HAVING A STONE GUARD AND METHOD FOR PRODUCING SAME - A bogie shaft for railway vehicles has a cladding which contains a metal component. The metal component is preferably electrochemically less refined, but no greater than exactly as refined, as a material of the bogie shaft. Corrosion on the bogie shaft can thereby be advantageously prevented. The metal material of the cladding is also able to effectively protect the bogie shaft against stone impact. The cladding can be advantageously applied by cold gas spraying, or a sleeve can be bent around the bogie shaft for forming the cladding. The cladding can advantageously contain particles that can make it more resistant to stone impact. The particles can be made, for example, of hard materials, of particularly ductile particles, or of particles made of a memory shape alloy. | 08-15-2013 |
