Numerous experimental studies have already established the fact that surface texturing can successfully improve the hydrodynamic performances of lubricated contacts. In a 2005 review paper, Etsion [1] offered a synthesis of these works and showed that surface texturing can benefit a large variety of tribological applications such as mechanical seals, thrust bearings or piston rings. However, the physical interpretation of the effects induced by textures still represents a subject of debate within the tribological community. The earliest investigation with regard to surface textures dates back to the 1960’s and is attributed to Hamilton et al. [2]. The authors reported that the cavitation phenomenon induced by small irregularities is essential, as it allows high film pressures to overbalance low film pressures due to an antisymmetric pressure distribution.
