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.

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.

On the Crystallinity and Durability of ZDDP Tribofilm [PDF]
Tribology Letters, 2019 Abstract 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, mixed lubrication conditions, where the risk of surface damage is increased. Consequently, the performance and durability of

Tribochemical investigation of ZDDP tribofilm [PDF]
, 2021 The current trend for using lower-viscosity lubricants with the aim of improving fuel efficiency of mechanical systems means that machine components are required to operate for longer periods in thin oil film, mixed and boundary lubrication conditions, where the risk of surface damage is increased. For this reason, the role of tribofilms generated from
