Abstract (technical / expert description):

Within the scope of the collaboration project between
the Institute of Engineering Design (KTmfk) and the LFT,
microstructures are developed especially for the tribological system of
cam follower matchings, as a representative of highly loaded revolving
sliding contacts, with the objective of friction reduction. A focus of
the project is the technological realization of components with
microstructured surfaces by a combined extrusion micro coining process
coping with the demands of large-lot production. Due to filigree
dimensions of microsructures surface characterization is of vital
importance as a junction between the design of micro coining tools and
the manufacturing of microstructured components. In a near-operation
test rig a friction reduction of up to 17% was realized by
microstructured surfaces in comparison to polished surfaces.
