SFB 483:  High-Performance Sliding and Friction Systems Based on Advanced Ceramics

• Subject Area: Materials Science and Engineering
• Term: from 2000 to 2011
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 5483414

Engineering ceramics offer a great potential for applications under high mechanical, tribological, thermal and corrosive loads due to their unique combination of high hardness, stiffness, chemical, thermal and wear resistance with low density. Nevertheless at present ceramic materials are not much used for mechanically and/or tribologically loaded systems of real large-scale production, although the use of these materials could not only lead to technical but also to ecological and economical advantages. Therefore the aim of the collaborative research centre 483 is the development of the tools necessary for the successful application of engineering ceramics under high tribological and mechanical loads using a scientific approach. The new developed concepts will not only be applicable to the exemplarily choosen systems (continuously variable transmission (CVT), high performance clutches, high pressure fuel injection pumps, sliding components for piston pumps in aggressive environment) but also be transferable to many other technical systems. The successful application of engineering ceramics in fastidious products will be promoted or in many cases even made possible for the first time by the overall scientific treatment of the whole process from the provision of the necessary design tools, materials, testing techniques and quality assurance to the realization of first prototypes.
