Planning surface texturing for reduced friction in lubricated sliding using surface roughness parameters skewness and kurtosis

Abstract

The aim of this research was to confirm skewness and kurtosis parameters as two main roughness parameters which describe tribological properties of contact surfaces, especially pointing out their application in surface texturing. Based on our previous virtual texturing findings, steel samples were laser textured in a manner to achieve micro-channels with different spacing and width of the channels. Lubricated tests under different contact conditions were done to evaluate their influence on friction. It was confirmed that higher S_ku and more negative S_sk can be used for planning surface texturing.
