On the Crystallinity and Durability of ZDDP Tribofilm [PDF]
Tribology Letters, 2019 Abstract The current trend for using lower-viscosity lubricants with the aim of improving fuel economy of mechanical systems means that machine components are required to operate for longer periods in thin oil film, mixed lubrication conditions, where the risk of surface damage is increased. Consequently, the performance and durability of

Tribochemical investigation of ZDDP tribofilm [PDF]
, 2021 The current trend for using lower-viscosity lubricants with the aim of improving fuel efficiency of mechanical systems means that machine components are required to operate for longer periods in thin oil film, mixed and boundary lubrication conditions, where the risk of surface damage is increased. For this reason, the role of tribofilms generated from

Palladium Nanoparticle-Enabled Ultrathick Tribofilm with Unique Composition
ACS Applied Materials & Interfaces, 2018 There is a consensus that savings of 1.0-1.4% of a country's gross domestic product may be achieved through lubrication R&D. Recent studies have shown great potential for using surface-functionalized nanoparticles (NPs) as lubricant additives to enhance lubricating performance.

Boundary Friction of ZDDP Tribofilms [PDF]
Tribology 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

Structure and Formation of Soot Particles from Tribofilm Decomposition Under Real Engine Conditions [PDF]
, 2020 Lubrication of an internal combustion engine is critical for unwanted energy and material losses. Zinc dialkyldithiophosphate (ZDDP) is a commonly used anti-wear additive that forms by in situ decomposition a protecting interface between sliding surfaces.

Synthesis of ultrathin two-dimensional metal-organic framework nanosheets for lubricant additives
Materials & Design, 2022 Two-dimension (2D) nano materials are diffusely employed as lubricant additives. In this paper, three kinds of ultrathin 2D metal-organic framework (MOF) nanosheets with different metal ions (Ni2+, Zn2+, and Cu2+) were successfully synthesized by ...
