Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method prepares a repair material for and repairs a damage point in the surface of cast parts. Spray particles having the same cast structure as the cast part are used as materials. The particles are applied to the damage point by cold gas spraying. The cold gas spraying is performed such that the spray particles are not melted and, advantageously, the cast structure is retained after the spray particles contact the repair point. The repair point can thus be advantageously furnished with the same properties as the rest of the component to be repaired. The repair material can be produced in that a cast part having the required cast structure is reduced to small pieces.

Abstract: In a method and apparatus for the optical inspection of a matt surface of an object, the surface having a random texture, for example a tile (11) to find cracks (12), in a first step digital images of the surface are created by an image sensor (K) whereby the surface is illuminated from different directions by light sources (B). In a second step sub-images of the regions of interest are created from the images. In a third step the cracks are detected in the sub-images by digital image processing, generating abnormality sub-charts showing the putative cracks. In a fourth step for each region of interest a joint abnormality chart is generated by fusion of the sub-charts and in a fifth step the cracks are detected in each of the joint abnormality charts of each region of interest.

Abstract: 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.
