Structured free-water clusters near lubricating surfaces are essential in water-based lubrication [PDF]
Journal of The Royal Society Interface, 2016 Water-based lubrication provides cheap and environmentally friendly lubrication and, although hydrophilic surfaces are preferred in water-based lubrication, often lubricating surfaces do not retain water molecules during shear. We show here that hydrophilic (42° water contact angle) quartz surfaces facilitate water-based lubrication to the same extent ...

Plastic–elastic Model for Water-based Lubrication Considering Surface Force
Chinese Journal of Mechanical Engineering, 2022 Water-based lubrication is an effective method to achieve superlubricity, which implies a friction coefficient in the order of 10−3 or lower. Recent numerical, analytical, and experimental studies confirm that the surface force effect is crucial for ...

Air cushioning with a lubrication/ inviscid balance [PDF]
, 2003 The air cushioning effect in the gap between an almost inviscid body of water and a nearby solid wall (or another body of water) is studied theoretically and is found to depend on predominantly lubricating forces in the air, in certain applications.
