Despite the fact that ceramic engineering materials are distinguished by such advantages as high hardness, thermal resilience and resistance to wear and corrosion, manufacturers are currently tending to be hesitant about introducing them into practice. The scientists engaged in the collaborative research centre Highly Stressed Slip and Friction Systems based on Ceramic Engineering Materials" at Karlsruhe University are aiming to employ selected components -- sets of synchronisation rings from gearboxes , clutch systems, crankshafts for pumps, high-pressure pumps for direct injection car engines -- to discover the tools required for the employment of these materials under thermal-mechanical loads.

A new collaborative research centre has been established at Hanover University entitled "The Process Chain for Manufacturing Precision-forged, High-performance Components". Its aim is to effect a drastic curtailing of the process chain by integrating various production processes and replacing cutting processes with precision-forging techniques. This should lower production costs, reduce energy and material expenditure and lead to long-term reductions in investment costs. Speaker: Prof. Dr.-Ing. Eckart Doege, Institut fur Umformtechnik und Umformmaschinen (IFUM), tel.: 0511/762 2164
The "Development, Production and Quality Assurance of Microcomponents formed from Metallic and Ceramic Materials" is the subject of a new collaborative research centre at Karlsruhe University (TH). The studies are based on a holistic review of the process chain embracing the design of the microcomponent, its production and, finally, its quality assurance. The aim is to make the forming processes, micro-casting and micro-powder injection moulding, available for the manufacture of miniaturised, three-dimensional ceramic and metal components. Speake
