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 in contact recording

Tribology Letters, 2001
Even though the flying height is approaching molecular dimensions, it is expected to decrease as the areal recording density is increased. This study employs a new low-velocity test to obtain ultralow flying height with sustained intermittent asperity contacts and random seek accessing in a region near the middle diameter of the disk. Sensitive surface

Tribochemistry of Some Ferrocene Derivatives

A S L E Transactions, 1983
An investigation was made of the behavior of different ferrocenyl alcohols and ferrocenyl sulfides as wear-reducing additives in paraffin oil. From measurements of wear as determined by four-ball apparatus, and extensive examination of products being formed by the ferrocenyl alcohols during sliding, a carbocation model has been proposed which ...

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 of MoS3 Nanoparticle Coatings

Tribology Letters, 2014
The tribology of nanoparticles based on transition metal dichalcogenides has been studied extensively. However, evaluation of metal chalcogenides with other stoichiometries has been lacking. We have studied the friction, endurance, and tribochemistry of bonded molybdenum trisulfide (MoS3) nanoparticle-based coatings for the first time. A facile aqueous

Tribochemistry of Cyclopentadienyl Organometallic Compounds

A S L E Transactions, 1987
The tribological behavior of some transition metal complexes is first described. The tested organometallic complexes are divided into three classes according to the concepts of coordination chemistry and some hypotheses about the tribochemical reactivity of the complexes with metallic surfaces.

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.

Head material effects on interface tribochemistry

IEEE Transactions on Magnetics, 1994
Sliding experiments between sliders made of different materials and magnetic thin-film disks were performed in a vacuum and an ambient in order to shed light on material effects in tribology. Al/sub 2/O/sub 3/-TiC, amorphous silicon, amorphous carbon, MnZn ferrite, and sapphire were chosen for their current or potential use as head substrate materials.
