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.

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 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 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 ...

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.

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 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 ...

Gelatinization and Melting of Starch and Tribochemistry in Extrusion
Starch - Stärke, 1993AbstractCooking of starch is traditionally achieved by supplying sufficient thermal energy to it as in baking and broiling processes. Whereas in extrusion cooking, both thermal and shear energy are usually present in doing the job. The relative importance of each of the two energy sources are difficult to assess in the process. The interactions between

Macroscale solid superlubricity from the perspective of tribochemistry
Advances in Colloid and Interface ScienceSuperlubricity, featuring near-zero friction, has attracted much attention due to its effectiveness in addressing energy crises. The underlying mechanism of solid superlubricity is incommensurate contact. Nowadays, relying on incommensurability and weaken size effect by reducing the contact area is an effective strategy for constructing macroscale ...
