“…Nowadays, several roughness parameters such as kurtosis, S ku , skewness, S sk , reduced valley depth, S vk , and the mean absolute profile slope, Á a , have become further adopted for the investigation of surface behavior under specified contact conditions. [15][16][17][18] Experimental results 14 have confirmed the sensitivity of the friction to those parameters. Indeed, low friction was detected for negative skewness, S sk , high kurtosis, S ku , and smaller mean absolute profile slope, Á a .…”

This study addresses the effects of roughness anisotropy in the tribological behavior of AA5083. Wear tests were carried out using a reciprocating tribometer under a contact pressure of 200 MPa. Sliding was performed on three topographic orientations. The friction force was recorded instantaneously. Furthermore, microscopic analyses were conducted for the purpose of characterizing the wear mechanisms. The findings proved the sensitivity of friction and wear of the initial surface properties. A numerical model of the reciprocated test was, in addition, developed upon ABAQUS/Explicit to better understand the evolution of equivalent plastic deformation during sliding. The proposed model is able to simulate a real surface profile described using python scripts. The model was found very useful in highlighting the significant effect of surface anisotropy on the stress distribution and plastic deformation.
