“…For instance, different textures (parallel and perpendicular grooves as well as dimples) on brass reduced friction after running-in and the corresponding wear rates for all textures in comparison to smooth brass ( Figure 1). This was linked to the entrapment of wear debris in the textures [68]. Temporal evolution of COF during dry ball-on-disk tests of smooth and textured brass samples, with corresponding 3D topographical maps.…”

“…Since then, other studies have reported lower friction [66][67][68][69][70][71][72][73] and reduced wear [66, 68-70, 72, 74, 75] on textured surfaces attributed to the ability of textures to trap wear debris. For instance, different textures (parallel and perpendicular grooves as well as dimples) on brass reduced friction after running-in and the corresponding wear rates for all textures in comparison to smooth brass ( Figure 1).…”

Surface texturing and solid lubricants have demonstrated the ability to substantially reduce friction and wear under dry conditions. In recent decades, these two technologies have been combined to leverage the advantages of both for superior tribological performance. This review article first summarizes the state-of-the-art regarding surface texturing and solid lubricants, including soft metals, polytetrafluoroethylene, diamond-like carbon and 2D layered materials. Then, the synergy between surface textures and solid lubricants is discussed, with particular emphasis on the underlying mechanisms. Finally, gaps in the existing understanding of these synergies are identified and opportunities for future research are suggested.

Controlling Friction and Wear with Anisotropic Microstructures in MoN-Coated Surfaces

This study considers anisotropic microstructures with typical dimensions of a few 10 µm which have been created on steel surfaces by laser surface texturing (LST). It is shown that the subsequent deposition of thin molybdenum nitride coatings by high-power impulse magnetron sputtering (HiPIMS) leads to surfaces that conserve the surface microstructures and exhibit a remarkably large resistance against mechanical wear. Tribological experiments with steel counter bodies are substantially influenced by the relative orientation of the structures and the wear track. Both friction and wear are shown to be modified by more than 30%, with the main effect being the removal of abrasion particles from the mechanical contact. Experiments with alumina counter bodies that hardly provide wear particles show that the orientation has no effect on the abrasion of the counter body. The novelty of the article lies in the combination of MoN coatings with surface texturing.

Steel surfaces have been patterned by laser surface texturing (LST) to create anisotropic microstructures with typical dimensions of a few 10 micrometers. The subsequent deposition of thin molybdenum nitride coatings by high power impulse magnetron sputtering (HiPIMS) leads to surfaces that conserve the surface microstructures and exhibit an extraordinarily large resistance against mechanical wear. Tribological experiments with steel counter bodies show a substantial influence of the relative orientation of structures and wear track on friction and wear. It is pointed out that the main effect is the removal of abrasion particles from the mechanical contact. Analogue experiments with alumina counter bodies that hardly provide wear particles show that the orientation effect is absent.
