Use of the Roughness Parameters Ssk and Sku to Control Friction-A Method for Designing Surface Texturing

The aim of this work was to show that with the use of the surface roughness parameters S-sk and S-ku we can predict tribological behavior of contact surfaces and use these parameters to plan surface texturing. This article presents a continuation of our research on virtual texturing and experimental work on surface textures in the form of channels. For this investigation, steel samples were laser surface textured in the shape of dimples with different spacings between the dimples and different dimple depths. The experimental results confirmed that the parameters S-sk and S-ku can be used to design the surface texturing, where a higher value of S-ku and more negative S-sk lead to lower friction.
