Tribological performance of microstructured surfaces with different wettability from superhydrophilic to superhydrophobic

Biosurface and Biotribology, 2020
The anti-friction function of superwetting surfaces with superhydrophobicity has been demonstrated. However, the influence regularity of wettability to tribological performance, and the underlying mechanism are still unclear.

Preliminary Study of the Effect of Micro-Scale Dimple Size on Friction and Wear under Oil-Lubricated Sliding Contact

Tribology Online, 2011
One of the conclusively presumed effects of micro-scale dimples under oil-lubricated conditions is that can serve as oil reservoirs and play a role in promoting the retention of a lubricating film.
