Reduzierung von Reibung und Verschleiß durch Mikrostrukturierung und oberflächennahe plastische Verformung

The focus of the paper is the design and manufacturing of friction optimized surfaces with microstructures. Selected microstructuring technologies especially the manufacturing of microstructures with incremental micro forming by round rolling and plastic deformation by ultrasonic powered tools are described. For a better understanding of the mechanisms of a certain surface quality or a defined, determined surface structure for tribological behavior, a detailed interpretation of the effects and mechanisms in and on microstructures is needed. A new measuring method and an approach for 3D-parameters to describe the contact behavior are derived for an improved description of friction and wear optimized surfaces
