Transient processes of MoS₂ tribofilm formation under boundary lubrication [PDF]

, 2016
A tribochemistry study that involves the application of Raman spectroscopy surface analysis has been undertaken to understand the time-dependent tribochemical reactions, for lubrication by Molybdenum dialkyl-dithiocarbamate (MoDTC) occurring in boundary ...

Tribological properties of novel palygorskite nanoplatelets used as oil-based lubricant additives

Friction, 2020
Layered palygorskite (PAL), commonly called attapulgite, is a natural inorganic clay mineral composed of magnesium silicate. In this study, an aqueous miscible organic solvent treatment method is adopted to prepare molybdenum-dotted palygorskite (Amo-PMo)

Correlation between Nano-Mechanical and Macro-Tribological Properties of Tribofilms Derived from Organic Phosphoric Additives

Tribology Online, 2016
Correlation between nano-mechanical and macro-tribological properties of the tribofilm derived from phosphoric additives was investigated. Macro friction test was performed at steel/steel contact under lubrication with poly-alpha olefin (PAO) containing ...

Tribofilms on CoCrMo alloys: Understanding the role of the lubricant [PDF]

Biotribology, 2019
The tribological activation of a passive metal alloy in an aqueous biological environment have been highlighted by many researchers; better known as bio-tribocorrosion. Tribocorrosion processes, which can be found at a number of metal-based biomedical implant interfaces, can be affected by lubricant species such as proteins, amino acids and salts.

Electrified Damage in Motion Systems

Advanced Engineering Materials, Volume 28, Issue 15, 5 August 2026.
The electrified damage in motion systems is a fundamental framework presenting the degradation pathway arising from the coupling of electrical energy transport with mechanical contact and interfacial chemistry. The framework positions electrified damage as a distinct degradation regime with unique characteristic surface morphologies and failures of ...

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels

Advanced Materials Interfaces, Volume 13, Issue 15, 4 August 2026.
When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...

XPS study of the influence of temperature on ZnDTP tribofilm composition [PDF]

Tribology Letters, 2006
Antiwear additives, such as zinc dialkyldithiophosphate (ZnDTP), find application in many different industrial sectors. Although it is understood that certain ZnDTP concentrations need to be used to achieve an effective antiwear performance, there has been very little work published concerning the effect of temperature on the interactions of the ...
