Use of FIB to Study ZDDP Tribofilms [PDF]
Tribology Letters, 2018 Focussed ion beam milling (FIB) followed by TEM has been used to study ZDDP tribofilms on rubbed steel surfaces. It has been found that the impact of high energy platinum and gallium ions during FIB causes significant morphological and structural changes to the uppermost 30–50 nm of a ZDDP tribofilm.

Lubrication Science, Volume 34, Issue 1, Page 1-29, January 2022., 2022 Abstract The most remarkable difference between electric vehicles (EVs) and conventional ones is the fuel burning dependency of the internal combustion engine, while the emerging EVs operate on electric motors. These alternations create staggering shifts in both lubricants' market demand and performance specifications.

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 ...

Lubrication Science, Volume 33, Issue 2, Page 100-111, March 2021., 2021 Abstract The aim of the work is to improve tribological properties of an ATF oil by means of additives. Two ionic liquids (IL) and one IL with 0.1 wt.% graphene were chosen as candidates. The ILs were selected because of their promising surface interactions and proven synergy with anti‐wear additives.
