Influence of Succinimide Dispersants on Film Formation, Friction and Antiwear Properties of Zinc Dialkyl Dithiophosphate [PDF]

, 2012
ZDDP (zinc dialkyldithiophosphate) is arguably the most successful antiwear additive ever employed in crankcase engine lubricants. It was originally used as an antioxidant and shortly afterwards recognized for its antiwear and extreme pressure ...

Enhanced Growth of ZDDP-Based Tribofilms on Laser-Interference Patterned Cylinder Roller Bearings

Lubricants, 2017
Laser surface texturing has been successfully applied in the past to various machine elements in order to improve their tribological performance. In this study, direct laser interference patterning was used to produce periodic cross-like surface patterns

Influence of roughness on ZDDP tribofilm formation in boundary lubricated fretting [PDF]

, 2012
Influence of initial surface topography on tribofilm formation in ZDDP lubricated contact was analysed. A small displacement fretting tests with sinusoidal motion were carried out in classical sphere/plane configuration.

An in-situ synchrotron XAS methodology for surface analysis under high temperature, pressure and shear [PDF]

, 2017
The complex tribochemical nature of lubricated tribological contacts is inaccessible in real time without altering their initial state. To overcome this issue, a new design of a pin-on-disc tribological apparatus was developed and combined with ...

Friction Modelling in Boundary Lubrication Considering the Effect of MoDTC and ZDDP in Engine Oils

Tribology Online, 2011
A predictive friction model has been developed in boundary lubrication conditions to understand the sensitivity of the model to molybdenum dithiocarbamate (MoDTC), a friction modifying additive and zinc dialkyldithiophosphate (ZDDP), an antiwear additive

Formation mechanisms of zinc, molybdenum, sulfur and phosphorus containing reaction layers on a diamond‐like carbon (DLC) coating Bildungsmechanismen von zink‐, molybdän‐, schwefel‐ und phosphorhaltigen tribochemischen Reaktionsschichten auf einer diamantähnlichen Kohlenstoffbeschichtung (DLC)

Materialwissenschaft und Werkstofftechnik, Volume 51, Issue 7, Page 1009-1030, July 2020., 2020
Tribochemical reactive formed layers on diamond‐like carbon (DLC) after tribological testing were analyzed. Hereby, the formation of zinc, molybdenum, sulfur and phosphorus containing reaction layers could be identified using Raman spectroscopy and scanning electron microscopy.
