Lubrication Science, Volume 33, Issue 2, Page 100-111, March 2021., 2021 Abstract The aim of the work is to improve tribological properties of an ATF oil by means of additives. Two ionic liquids (IL) and one IL with 0.1 wt.% graphene were chosen as candidates. The ILs were selected because of their promising surface interactions and proven synergy with anti‐wear additives.

Substituent effects on the mechanochemical response of zinc dialkyldithiophosphate
Molecular Systems Design & Engineering, 2022 We show how the tribofilm growth rate of zinc dialkyldithiophosphate (ZDDP) changes for different alkyl substitutents under carefully controlled temperature and stress conditions.

Green Alternatives to Zinc Dialkyldithiophosphates: Vanadium Oxide-Based Additives
ACS Applied Engineering Materials, 2023 A functionalized vanadyl(IV) acetylacetonate (acac) complex has been found to be a superior and highly effective antiwear agent, affording remarkable wear protection, compared to the current industry standard, zinc dialkyldithiophosphates (ZDDPs). Analysis of vanadium speciation and the depth profile of the active tribofilms by a combination of X-ray ...

Understanding the effect of water on the transient decomposition of zinc dialkyldithiophosphate (ZDDP) [PDF]
Tribology International, 2021 The effect of water on the transient kinetics of the decomposition reaction of zinc dialkyldithiophosphate (ZDDP) additive has been investigated using X-ray photoelectron spectroscopy (XPS). Water was found to have a long-lasting detrimental effect on ZDDP triboreactive film layers by changing their composition depending on their proximity to the metal
