Tribological Conditioning of Cylinder Running Surfaces

In the wake of increasing performance requirements for internal combustion engines, regarding downsizing, and rising mobility, efficient manufacturing processes are gaining significance in Far Eastern markets. Also in consideration of increasing emission limits for these 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 subsequent surface integrity are in the focus of considerations. Using tribological analysis of the mechanical running-in behavior of cylinder running surfaces, conclusions will be drawn on the impact of the last honing step of the engine production. These investigations are 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 like burnishing are investigated.
