Microstructuring of Thermo-Mechanically Highly Stressed Surfaces: Final Report of the DFG Research Group 576 (Lecture Notes in Production Engineering)

The fuel consumption of a modern combustion engine is one of the most important purchase criteria in contemporary society. Increasing oil prices and exhaust emissions taxes force the automotive industry to continuously improve the vehicle engines. The fuel consumption is closely related to the frictional losses of an engine. New material pairings or constructive modifications of the piston group can reduce such losses. Another innovative concept to lower the frictional forces is the micro-structuring of thermo-mechanically highly stressed surfaces. Within an interdisciplinary research group sponsored by the German Research Foundation, scientists at the Leibniz Universität Hannover and Universität Kassel have been working together to investigate this research topic. This final report presents their findings and offers scope for further discussion. This contributed volume presents the final research results of the DFG Research Group 576, which is a joint initiative of five different institutes of the Leibniz Universität Hannover and the Universität Kassel, Germany. The research of the DFG Research Group 576 focuses on improving the tribological behavior of thermomechanically highly stressed surfaces, particularly on cylinder liner for combustion engines. The target audience primarily comprises researchers and experts in the field but the book may also be beneficial for graduate students who want to specialize in the field [source : 4e de couv.] Front Matter....Pages I-XIV 1 Introduction....Pages 1-1 2 Project overview....Pages 2-8 3 Methods and models for the design of microstructures....Pages 9-27 4 Microstructuring by means of cutting processes....Pages 28-57 5 Microstructured thermally sprayed surfaces....Pages 58-92 6 Surface characterisation based on optical metrology....Pages 93-118 7 Tribological mechanisms of microstructures....Pages 119-145 8 Test of cylinder liner under fired engine conditions....Pages 146-166 9 Own publications....Pages 167-169 Back Matter....Pages 170-175 The fuel consumption of a modern combustion engine is one of the most important purchase criteria in contemporary society.
