Lubrication in a Sea Water Environment
SAE Technical Paper Series, 1963<div class="htmlview paragraph">Since the Navy's habitat is the ocean area of the world, sea water is an environmental factor which must be reckoned with and, if possible, used to advantage where lubrication of ship' s machinery is concerned. Three situations within the above concept are (<span class="xref">1</span>) protection from ...

Analysis of the Interface Lubrication Performances of Water Lubrication Bearing
2020 Global Reliability and Prognostics and Health Management (PHM-Shanghai), 2020The paper explores effects of velocity on lubrication performances of water lubricated bearing. Variations between lubrication performances and velocity are obtained. Research show that velocity has important effects on lubrication performances.

The increasing ecological awareness and stringent requirements for environmental protection have led to the development of water lubricated bearings in many applications where oil was used as the lubricant. The chapter details the theoretical analysis to determine both the static and dynamic characteristics, including the stability (using both the ...

Applied Mechanics and Materials, 2014
Water-lubricated bearings have attracted increasing attention in recent years because of their environmental sustainability, simplified design, low cost, good cooling performance and low coefficient of friction. To show the characteristic of water lubrication more clearly, this paper quantitatively compares the lubrication performances of water ...

Water as a lubricant for graphite: A computer simulation study
The Journal of Chemical Physics, 2006The phase state and shear behavior of water confined between parallel graphite sheets are studied using the grand canonical Monte Carlo technique and TIP4P model for water. In describing the water-graphite interaction, two orientation-dependent potentials are tried.

Water droplet lubrication for micromachines
Materials Science, 2007Water droplets placed on hydrophilic surface decrease the friction coefficient in the process of sliding over the hydrophobic surface. The droplets placed between these surfaces sustain loads of up to 170 mN and the friction coefficient for these surfaces is equal to 1.1 · 10−3.

Water lubrication of PTFE composites
Industrial Lubrication and Tribology, 2015Purpose– The paper aims to present results on the friction and the wear of polytetrafluoroethylene (PTFE) and eight commercially available composites with PTFE matrix, for tests done on shoe/roller tribotester with water lubrication in open circuit. There are pointed out particular tribological processes within the superficial layers of the composites ...

Role of water in the lubrication of hydrogel
Wear, 2006Abstract In previous reports, the frictional property of hydrogel was evaluated by using the pin-on-disk type of friction tester. As a result, the hydrogel showed the change in a friction coefficient depending on the speed. The friction property of hydrogel is similar to the Stribeck curve.
