Lubrication regimes in mesothelial sliding

Journal of Biomechanics, 2005
To function normally, the lungs, heart, and other organs must undergo changes in shape and size, sliding against surrounding body walls. It is not known whether the delicate mesothelial surfaces covering these organs and body wall are in contact during sliding, or if hydrodynamic pressure in the lubricating liquid increases separation between their ...

Lubricant dynamics in sliding and flying

Journal of Applied Physics, 1991
The dynamics of molecularly thin liquid lubricant films in sliding and flying experiments is studied principally by scanning microellipsometry and complemented with both scanning x-ray photoelectron spectroscopy and infrared spectroscopy. Microellipsometric profiling of lubricant thickness is performed in situ, either dynamically or statically on films

Metallic sliding friction under boundary lubricated conditions: Investigation of the influence of lubricant at the start of sliding

Wear, 1995
Experiments are described in which a hard half-wedge, representing a scaled up model asperity, was indented into the horizontal surface of a relatively soft specimen with the specimen then moved in a direction parallel to its surface and normal to the wedge edge.

Sliding Bearing Lubrication Theory

2016
Sliding friction exists in the working process of sliding bearing. The advantages of sliding bearing include the stability, reliability, and noiseless. Requirement of the formation of lubrication film is to ensure the sufficient lubricant for the sliding bearing.

Ordering of a Thin Lubricant Film due to Sliding

Physical Review Letters, 2004
A thin lubricant film confined between two substrates in moving contact is studied using Langevin molecular dynamics with the coordinate- and velocity-dependent damping coefficient. It is shown that an optimal choice of the interaction within the lubricant can lead to minimal kinetic friction as well as to low critical velocity of the stick-slip to ...

The beneficial effect of slip on the hydrodynamic lubrication in the lubricated sliding contact

AIP Conference Proceedings, 2017
In micro-electro-mechanical system (MEMS) containing moving components, there is a need to achieve low friction and high load support by lubrication. However, many researches were focused only on how to improve the lubrication by texturing surfaces of the lubricating siding contact. Only few works dedicated to the application of the slip on the surface

The influence of lubricant polarity on the boundary lubrication of sliding steel contacts

Wear, 1981
Abstract The boundary lubrication and the wear of slowly moving concentrated contacts of steel LH-15 (similar to AISI 52100 steel) were studied as a function of lubricant polarity. The results obtained with a four-ball machine using different polar and non-polar lubricants do not corroborate the possible correlation between polarity and the antiwear ...
