Tribochemistry in ceramic lubrication

Lubrication Science, 1996
AbstractEffective lubrication systems are crucial to the successful application of ceramic materials in many advanced technologies. A review is given here of the tribochemistry of ceramic lubrication, including the effects of water, water‐based lubricants, hydrocarbons, additives and solid lubricants, on the friction and wear properties of ceramics ...

The Nature and Origin of Tribochemistry

Tribology Letters, 2002
Tribochemistry can be defined as the chemical reactions that occur between the lubricant/environment and the surfaces under boundary lubrication conditions. The precise nature of the chemical reactions is not well understood. What causes the reactions to take place is also a subject of speculation.

Tribochemistry of ultra-low friction fullerene-like carbon films in humid air

Applied Surface Science, 2020
Hydrogenated fullerene-like carbon (FL-C:H) films can exhibit macroscale superlubricity, which is expected to make energy and material losses in the mechanical motion systems very small and can be used in various applications.

Tribochemistry at lubricated interfaces

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1994
High resolution mass spectrometry is used to monitor in situ gaseous wear products that are generated during sliding of lubricated carbon–carbon interfaces in a vacuum. During the initial stages of sliding, significant amounts of polyperfluoroether lubricant fragments are detected, which resemble the mass patterns of scissioned lubricant in the thermal

Tribochemistry of gadolinium dialkyldithiophosphate

Wear, 1996
Abstract In the present paper, the tribological behaviors of gadolinium dialkyldithiophoshate (GdDDP) were evaluated on friction testers. There-after, the tribochemistry of GdDDP were investigated through scanning electron microscopy (SEM), Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS).

Tribochemistry of Materials

World Tribology Congress III, Volume 1, 2005
Tribochemistry refers to the contact chemistry occurs inside the wearing interface under boundary lubricated conditions. Since lubrication chemistry has been dominated by hydrocarbon-steel chemistry, other chemistry between insulators, semiconductors, carbon films and lubricants has not been explored extensively.

Tribochemistry and Superlubricity Induced by Hydrogen Ions

Langmuir, 2012
Friction behavior of aqueous solution at macroscale is quite different from that at nanoscale. At macroscale, tribochemistry usually occurs between lubricant and friction surfaces in the running-in process due to a high contact pressure, and most such processes can lead to friction reduction.

Tribochemistry in the analytical UHV tribometer

Tribology International, 1999
Abstract The knowledge of tribochemical reactions in boundary lubrication in the presence of lubricant additives is fundamental in order to improve chemical engineering of new molecules, multifunction compounds and to predict interactions between these additives.
