• Surface analysis
• Tribology
• Burnishing

In the wake of increasing performance requirements for internal combustion engines, regarding weight optimization coupled with increasing mobility in Far Eastern markets, efficient manufacturing processes gain significance. Also in consideration of increasing emission limits for combustion engines investigations regarding alternative technologies for the efficient manufacturing of performance-optimized cylinder running surfaces were carried out by the Institute of Manufacturing Technology and Quality Management. The microstructure of these surfaces and the surface integrity are in the focus of investigations. By using tribological analysis of the mechanical running-in behavior of cylinder running surfaces conclusions have been drawn on the impact of the last process step in the production of the cylinder surface. These investigations were carried out in terms of a possible conditioning of tribotechnical systems in their production and the concomitant reduction of friction and wear-intensive running-in processes. In this regard alternative finishing operations, such as burnishing processes are investigated.
