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.

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 ...

Shear activation of ZDDP reaction films in the presence and absence of nanodiamonds
Applied Surface Science Advances, 2022 We explore the impact of shear stress and nanodiamond (ND) additives on the formation temperatures of thermal- and tribo- reaction films of steel samples immersed in basestock oils containing zinc dialkyl dithio-phosphate (ZDDP) additives.

Revealing the interface nature of ZDDP tribofilm by X-ray photoelectron spectroscopy and atom probe tomography [PDF]
, 2020 Purpose To decrease wear and friction, zinc dialkyldithiophosphate (ZDDP) has been used in engine oil for several decades, but the mechanism of the tribofilm formation is still unclear. The purpose of this study is to characterize the chemical details of
