match | Above all, high-quality goods shall be disassembled at the end of their lifetime, either to get them repaired or to reuse their components. This can be achieved by component-friendly disassembly processes, increasing sustainable reuse of products considerably.

IW | Repair work carried out at offshore wind turbines poses new challenges: Researchers of the Institute of Materials Science (IW) generate data to make the finite element method also usable for the simulation of wet underwater welding.

ITA | In future, printed optical waveguides will be used for multimedia transmission in cars and aeroplanes. The requirements are correspondingly large bandwidths and three-dimensional forming. DFG approves another three years of research of OPTAVER research group, in which scientists from ITA and LZH work together with fellows from Nuremberg, Erlangen and Dresden.

IFUM/IMPT | Precise temperature control is a decisive factor during hot stamping: Only if the component part is cooled down fast enough, it is hardened sufficiently. For direct temperature measurement in the tool, researchers at IFUM and IMPT developed a thin-film sensor.

LZH | Aluminum engines save weight and fuel. A steel layer protects the inner surfaces of the cylinder from wear. For the layer to stick firmly, the surface must be rough. Laser-based roughening is an alternative to conventional processes such as corundum blasting or machining.

IW | Abrasive wear in joint protheses can induce inflammatory reactions and bone resorption. Researchers want to improve the frictional properties using human synovial fluid. The fluid’s distribution in the joints is improved when using a ceramic coating with capillary texture.

IFW | In the past, the polishing of dental products has been a manual machining process. The aim of researchers at IFW is to develop and implement an automated polishing process on a machine tool, thus creating an adaptive system which improves with every polishing process.

LZH | So far, the on-site welding, cutting or material removal of large and heavy components was only possible within narrow limits. The Laser Zentrum Hannover e.V. (LZH) and the SET Ltd. have now further developed a new mobile laser processing system to a prototype.
