Se Nanopowder Conversion into Lubricious 2D Selenide Layers by Tribochemical Reactions

Advanced Materials, Volume 35, Issue 42, October 19, 2023., 2023
A simple sprinkling of Se nanopowders onto sliding Mo and W thin films leads to the tribochemical in operando formation of lubricious 2D selenides. Due to the thermal and vacuum stability of the Se nanopowders they can be used to replenish sliding components with solid lubricants, avoiding the long‐lasting problem of transition metal ...

Influence of Soot on the Anti-Wear Property of MoDTC and ZDDP [PDF]

Cailiao Baohu, 2022
In order to investigate the influence of soot on the anti-wear property of molybdenum dialkyldithiocarbamate(MoDTC) and zinc dialkyldithiophosphate(ZDDP), the soot was added into different oil samples and then a four-ball machine friction experiment was ...

Dynamic Processes of Self‐Organization in Nonstationary Conditions of Friction

Advances in Tribology, Volume 2023, Issue 1, 2023., 2023
Self‐organization mechanisms of metastable dissipative structures during friction depending on base and oil functional additives for hypoid gears are considered. Research was conducted on a software‐hardware complex with simulation of gears’ operation in rolling with slipping conditions in start‐stop mode.

Detailed chemical analysis of a fully formulated oil using dielectric barrier discharge ionisation–mass spectrometry

Rapid Communications in Mass Spectrometry, Volume 36, Issue 14, 30 July 2022., 2022
Rationale Fully formulated oils (FFOs) are integral to automotive lubrication; however, detailed compositional analysis is challenging due to high levels of chemical complexity. In particular, existing mass spectrometric approaches often target particular FFO components, leading to poor analytical coverage of the overall formulation, with increased ...

Synergistic nano-tribological interaction between zinc dialkyldithiophosphate (ZDDP) and methyl oleate for biodiesel-fueled engines

Friction, 2020
In biodiesel-fueled compression-ignition (CI) engines, dilution by unburned biodiesel has been found to have adverse effects on the boundary lubrication properties of additives in fully formulated engine lubricants.

A review on potentials and challenges of nanolubricants as promising lubricants for electric vehicles

Lubrication Science, Volume 34, Issue 1, Page 1-29, January 2022., 2022
Abstract The most remarkable difference between electric vehicles (EVs) and conventional ones is the fuel burning dependency of the internal combustion engine, while the emerging EVs operate on electric motors. These alternations create staggering shifts in both lubricants' market demand and performance specifications.

Investigation of ionic liquids with and without graphene as lubricant additive for metal/metal and metal/PEEK contacts over a wide temperature range

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.
