Tribochemistry of phosphorus additives: Experiments and first-principles calculations [PDF]

, 2015
Organophosphorus compounds are common additives included in liquid lubricants for many applications, in particular automotive applications. Typically, organic phosphites function as friction-modifiers whereas phosphates as anti-wear additives.

Recovery of lubricant base oils using ionic liquid processes

, 2016
Two novel low-temperature ionic liquid processes are developed for the recovery of base oils from waste lubricant oils. One uses 3-(triethoxysilyl)-propylammonium-3-(triethoxysilyl)-propyl carbamate (TESAC), in which the waste lubricant base oil is ...

Friction properties of fluorinated carbons [PDF]

, 2013
In boundary lubrication regime, friction reduction and antiwear processes are associated to the presence of additives in the lubricating oils or greases.

Tribological manufacturing of ZDDP tribofilms functionalised by graphene nanoplatelets

JPhys Materials
3D Tribo-Nanoprinting (3D TNP), which uses a highly controllable tribological contact to deposit tribofilms, has been proposed as a manufacturing method for nanoscale structures.

ZDDP tribofilm formation under various rubbing conditions

, 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 surfaces of this material.

Comparison of Tribological Performance of Ashless Sulfur-Free Phosphite Ester Versus ZDDP Additives at Electrified Interfaces

Lubricants
In electric vehicle (EV) drivetrains, lubricant films must not only mitigate friction and wear but also manage stray currents to safely dissipate stray charge and avoid micro-arcing. This study directly compares how a conventional antiwear additive (ZDDP)
