On the mechanism of ZDDP antiwear film formation [PDF]
, 2016 Zinc dialkyldithiophosphate additives are used to control wear and inhibit oxidation in almost all engine oils as well as many other types of lubricant. They limit wear primarily by forming a thick, protective, phosphate glass-based tribofilm on rubbing ...

Formation of Nano Interface by Sliding between Hard Coatings and Metals in MoDTC Contained Oil
Tribology Online, 2022 The viscosity of motor oil gets lower in order to decrease resistance at region of the fluid lubrication. On the other hands, this causes increasing of friction at the boundary lubrication region.

The ta-C Hardness Effect on Wear Properties Under MoDTC Contained Boundary Lubrication
Tribology Letters, 2023 Abstract The wear acceleration of hydrogenated amorphous carbon under lubrication with molybdenum dithiocarbamate (MoDTC) is one of the problems to apply it to engine components. It is assumed that using high hardness tetrahedral amorphous carbon (ta-C) can easily solve the wear problem regardless of chemical wear by Mo degradable materials ...

Friction and wear response of vegetable oils and their blends with mineral engine oil in a reciprocating sliding contact at severe contact conditions [PDF]
, 2018 Although many studies investigating the tribological performance of pure vegetable oils have been conducted, a better understanding of vegetable oil tribological performance at extreme conditions is still needed. Similarly, little work has been carried
