Abstract



Microtextures on the rubbing surfaces may
influence the friction and wear performance of lubricated contacts. While this
approach has already reached industrial application for sliding contacts with
lower contact pressures, the effects for higher loaded EHL contacts are still
topic of basic research. For this reason, geometrically defined microtextures,
manufactured by a hot micro-coining process, were used for ball-on-disk experiments
and characterized with regard to their friction and wear behavior. Numerical EHL
simulation based on the full-system approach is applied, acting as a numerical
zoom into the contact and contributing to a better understanding of the
observed effects and phenomena. Particular attention is paid to the influence
of geometrical parameters of microtextures regarding depth, lateral dimensions
and position within the contact area. Hence, the importance of structural
parameters and microtexture position regarding the tribological behavior is verified
numerically and experimentally. Thus, it can be seen that deviations in those
parameters can have a strong influence on lubricating conditions, possibly overcompensating
beneficial effects induced by microtexturing.
