Understanding Tribofilm Formation Mechanisms in Ionic Liquid Lubrication [PDF]

open access: yesScientific Reports, 2017
Ionic liquids (ILs) have recently been developed as a novel class of lubricant anti-wear (AW) additives, but the formation mechanism of their wear protective tribofilms is not yet well understood.

Coupling effect of boundary tribofilm and hydrodynamic film

open access: yesCell Reports Physical Science, 2022
Summary: Reducing the friction and wear of dynamic interfaces has been a constant endeavor in the field of sustainability. Lubricants with two-dimensional atomic materials are operative frameworks proposed as promising candidates: they can together ...

The influence of slide–roll ratio on ZDDP tribofilm formation [PDF]

open access: yesTribology Letters, 2016
The anti-wear performance and action mecha- nisms of zinc dithiophosphate (ZDDP) have been investi- gated under various test conditions. The Mini Traction Machine–Space Layer Imaging (MTM–SLIM) is a widely used and useful method for monitoring tribofilm ...

Ti6Al4V-Bioglass-Copper Composites for Load-Bearing Implants. [PDF]

open access: yesAdv Healthc Mater
We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.

The impact of organic friction modifiers on engine oil tribofilms [PDF]

open access: yesRSC Adv., 2014
Organic friction modifiers (OFMs) are important additives in the lubrication of machines and especially of car engines where performance improvements are constantly sought-after. Together with zinc dialkyldithiophosphates (ZDDPs) antiwear additives, OFMs

Boundary Friction of ZDDP Tribofilms [PDF]

open access: yesTribology Letters, 2020
AbstractThe frictional properties of ZDDP tribofilms at low entrainment speeds in boundary lubrication conditions have been studied in both rolling/sliding and pure sliding contacts. It has been found that the boundary friction coefficients of these tribofilms depend on the alkyl structure of the ZDDPs. For primary ZDDPs, those with linear alkyl chains

Self-healing WS2 tribofilms: An in-situ appraisal of mechanisms [PDF]

open access: yesScripta Materialia, 2021
Self-healing tribocoatings are being developed for aerospace applications to improve the lifetime and reduce the surface maintenance of components in motion. Here the tribo-induced self-healing behaviour of a WS2/a-C tribocoating has been evaluated for the first time by in-situ scanning electron microscopy (SEM) to evaluate the mechanisms of damage and

Use of FIB to Study ZDDP Tribofilms [PDF]

open access: yesTribology Letters, 2018
Focussed ion beam milling (FIB) followed by TEM has been used to study ZDDP tribofilms on rubbed steel surfaces. It has been found that the impact of high energy platinum and gallium ions during FIB causes significant morphological and structural changes to the uppermost 30–50 nm of a ZDDP tribofilm.
