Due to scarce resources coupled with increasing mobility requirements,
resource-efficient machine and motor elements are vital. Therefore,
surfaces in lubricated tribological contacts can be microtextured,
enabling improved lubricating conditions and friction behavior. While
this has already been shown for lower loaded contacts, the effects for
higher loaded, application-oriented EHL contacts are topic of basic
research. Therefore, geometrically defined microtextures are adapted to
the tribological system of the tappet/camshaft contact in the valve
train of combustion engines as a demonstrator. The tribological
performance in respect to lubricating conditions, friction and wear
behavior is analyzed on single cam/tappet component test-rigs. EHL
simulation is used as ‘numerical zoom’ into a section of the contact
area contributing to better understanding of effects and observed
