Tribochemistry of Bulk Zinc Metaphosphate Glasses [PDF]

Tribology Letters, 2010
Zinc polyphosphate glasses are the principal component of the antiwear tribofilms formed on steel surfaces in the presence of additives, such as zinc dialkyldithiophosphates. In this work, amorphous, zinc metaphosphate glasses have been synthesized and characterized by means of X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR ...

Friction and Wear Properties of Tetrahedral Si-Containing Hydrogenated Diamond-Like Carbon Coating under Lubricated Condition with Engine-Oil Containing ZnDTP and MoDTC

Tribology Online, 2017
In this study, we investigated tribological properties of “tetrahedral” Si-containing hydrogenated DLC coating (TMS coating) during sliding against steel or cast-iron lubricated with engine-oil containing MoDTC and ZnDTP additives.

Physicochemistry aspects on frictional interfaces

Friction, 2017
Friction exists wherever relative motion occurs and is the main source of energy consumption. Lubrication plays a significant role in improving fuel efficiency, reducing emissions, and prolonging the service life of machines. Surface interactions between

Modelling interfacial tribochemistry in the mixed lubrication regime [PDF]

, 2018
The need to reduce the cost of components is driving more and more machine elements to operate under mixed lubrication conditions. With higher operating pressures, the lubricant film is becoming thinner and eventually reaches nanometre scales ...

Tribochemical Interface Engineering of TiS4–Argyrodite Composites for Metal Sulfide‐Based Solid‐State Batteries

Batteries &Supercaps, Volume 9, Issue 9, September 2026.
Amorphous TiS4 is studied structurally and electrochemically as a dry‐processed cathode for sulfidic solid‐state batteries. High‐energy ball milling (HBM) outperforms low‐energy milling, delivering up to 1110 mAh gS−1. HBM dry‐film cathodes retain 950 mAh gS−1 after 80 cycles, establishing tribochemical processing as a key strategy for high‐energy ...
