ZDDP Tribofilm Formation and Removal
Tribology LettersAbstract While ZDDP tribofilm formation has been widely studied, the mechanism of ZDDP tribofilm removal during rubbing is still unclear. The study employs a ball on disc tribometer to monitor ZDDP tribofilm development in rolling-sliding, mixed lubrication conditions.

ZDDP Tribofilm Formation on Non-Ferrous Surfaces [PDF]
Tribology Online, 2020 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, boundary and mixed lubrication conditions ...

Understanding Tribofilm Formation Mechanisms in Ionic Liquid Lubrication [PDF]
Scientific Reports, 2017 Ionic liquids (ILs) have recently been developed as a novel class of lubricant anti-wear (AW) additives, but the formation mechanism of their wear protective tribofilms is not yet well understood.

Voltage-Driven Growth of Phosphorus Tribofilms. [PDF]
Tribol LettAbstract Ashless phosphorus-based lubricant additives, which are increasingly deployed in next-generation formulations, often suffer from slow tribofilm formation and poor film stability, limiting their effectiveness under demanding operating conditions.

Effect of Sliding on the Relation of Tribofilm Thickness and Wear
Lubricants, 2023 The formation of tribofilms depends on temperature, shear stress, availability of the related chemical components, and characteristics of the near surface region, e.g., roughness and surface chemistry.
