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 ...

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 ...

Progress in Tribological Properties of Nano-Composite Hard Coatings under Water Lubrication
Lubricants, 2017 The tribological properties, under water-lubricated conditions, of three major nano-composite coatings, i.e., diamond-like carbon (DLC or a-C), amorphous carbon nitride (a-CNx) and transition metallic nitride-based (TiN-based, CrN-based), coatings are ...
