ACS Applied Materials & Interfaces, 2020 Zinc dialkyldithiophosphate (ZDDP) is added to engine lubricants to reduce wear and ensure reliable operation. ZDDP reacts under rubbing conditions to form protective zinc/iron phosphate tribofilms on steel surfaces. Recently, it has been demonstrated that this process can be promoted by applied stresses in lubricated contacts, as well as temperature ...

Chemical analysis of additives included in fully formulated oils using high-performance liquid chromatography-tandem mass spectrometry. [PDF]
Rapid Commun Mass SpectromRationale Fully formulated oils (FFOs) are chemically complex petrochemical products composed of base oil and additive mixtures that are employed in automotive engines to provide lubrication. In particular, the additive portion of FFOs is often precisely controlled to tailor the resultant formulation to a specific role.

Atmospheric pressure matrix-assisted laser desorption/ionization mass spectrometry of engine oil additive components. [PDF]
Rapid Commun Mass Spectrom, 2022 Rationale The efficiency of lubricants strongly depends on the content of functional additives. In order to assess the chemical and structural changes taking place in the lubricating oil and its additives during operation, it is essential to develop a method for simple and prompt analysis.

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 ...
