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.

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 ...

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 ...

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.

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.
