Characterization of ZDDP and ionic liquid tribofilms on non-metallic coatings providing insights of tribofilm formation mechanisms [PDF]
Wear, 2015 Abstract Lubricant anti-wear additives are known to chemically interact with metallic surfaces to form a self-healing, wear-protection tribofilm. Their interactions with non-metallic surfaces are however less understood. Here we report recent findings on whether and how a zinc dialkyldithiophosphate (ZDDP) and a phosphonium–organophosphate ionic ...

Structure and Formation of Soot Particles from Tribofilm Decomposition Under Real Engine Conditions
, 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.

ZDDP tribofilm formation under various rubbing conditions [PDF]
, 2018 ZDDPs (zinc dialkyldithiophosphates) have been widely used as antiwear additives in engine oil for the last 70 years. Initially, since engine parts were manufactured from cast iron, ZDDPs were required to protect them by forming tribofilms on the ...

The Effect of Temperature on Lubrication Property with MoDTC-Containning Lubricant
Tribology Online, 2018 The effect of temperature on the lubricity of molybdenum dithiocarbamate (MoDTC) was investigated by a ball on disk tribometer with lubricant oil containing MoDTC and calcium sulfonate (CaSU) at temperatures of 25˚C, 40˚C, 60˚C and 80˚C.

Understanding the Fundamentals of the Texture and Tribofilm Evolution
Procedia Manufacturing, 2020 Abstract Several manufacturing processes experience the interaction between and among mating surfaces under the boundary lubrication (BL) regime. Textures evolve as a result of these multi-parametric interactions where physical and chemical parameters play a significant role.

Use of FIB to Study ZDDP Tribofilms [PDF]
Tribology 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.

Tribological synergy between classical ZDDP and innovative MoS2 and MoO3 nanotube additives at elevated temperatures; pp. 178-184 [PDF]
Proceedings of the Estonian Academy of Sciences, 2019 One of the most important drawbacks limiting the application of MoS2 nanotubes (NTs) as an oil additive is their temperature sensitivity. Recent studies showed that MoS2 NTs can be substituted by MoO3 NTs in conjunction with S-containing lubricants by ...
