Investigating the Effect of Water Contamination on Gearbox Lubrication based on Motor Control Data from a Sensorless Drive [PDF]
, 2014 Water is one of the most significant destructive contaminations to lubricants which in turn lead to more power consumption and early damage to rotating machines.

The role of water in fault lubrication [PDF]
Nature Communications, 2018 AbstractThe friction between two adjacent tectonic plates under shear loading may dictate seismic activities. To advance the understanding of mechanisms underlying fault strength, we investigate the frictional characteristics of calcite in an aqueous environment.

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 ...
