Abstract: A lengthwise extended component contains of a support that possesses flow channels in the direction of its longitudinal axis. The support additionally possesses external surfaces that are offset to each other in the direction of the longitudinal axis as well as a lateral external surface. These external surfaces are provided with a layer of a thermally expansible and curable composition. Reinforcing components of this type are suitable for stiffening and/or reinforcing hollow supports, such as the A-, B- or C-pillars, the roof edges or the rocker panels of vehicles, especially passenger cars.

Abstract: The invention relates to a device, in particular for a laser-induced vacuum are discharge evaporator for depositing of multiple layers with a high level of purity and high deposition rates on large-area components. According to the invention, the material source for the coating material is in a source chamber which can be evacuated and can be separated in a vacuum-tight manner from the actual coating chamber in which the substrate to be coated is located. The evaporator can, in particular, be used for deposition of amorphous carbon layers which are hydrogen-free and superhard and/or which contain hydrogen, in conjunction with high-purity metal layers or for the reactive plasma-enhanced deposition of, for example, oxidic, carbide, nitride hard material layers of ceramic layers or a combination thereof. The corresponding plasma sources can be flange-mounted on any suitable coating chambers and, consequently, also combined with conventional coating processes, for example magnetron sputtering.
