Tribochemistry of gadolinium dialkyldithiophosphate
Wear, 1996Abstract 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).

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.

The Nature and Origin of Tribochemistry
Tribology Letters, 2002Tribochemistry 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 and Superlubricity Induced by Hydrogen Ions
Langmuir, 2012Friction 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 contact recording
Tribology Letters, 2001Even 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 in the analytical UHV tribometer
Tribology International, 1999Abstract 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.

Tribochemistry of Some Ferrocene Derivatives
A S L E Transactions, 1983An 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 ...

Role of Tribochemistry in Nanowear of Single-Crystalline Silicon
ACS Applied Materials & Interfaces, 2012The effects of counter-surface chemistry, relative humidity, and applied normal load on nanowear of single-crystalline silicon were studied with atomic force microscopy. In the absence of humidity, the silicon surface can resist mechanical wear as long as the contact pressure is lower than the hardness of silicon regardless of the counter-surface ...

Tribochemistry of Cyclopentadienyl Organometallic Compounds
A S L E Transactions, 1987The 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 of Selected Ceramic Materials
Solid State Phenomena, 2006Ceramics, especially nitrides, oxides and carbides, offer advantages over conventional tribological mating elements. Such solids usually are very stable chemically. However, under friction conditions they become quite reactive. It is even possible to say that the friction and wear behavior of ceramics might be more sensitive to the environment than ...
