Friction Modelling in Boundary Lubrication Considering the Effect of MoDTC and ZDDP in Engine Oils
Tribology Online, 2011 A predictive friction model has been developed in boundary lubrication conditions to understand the sensitivity of the model to molybdenum dithiocarbamate (MoDTC), a friction modifying additive and zinc dialkyldithiophosphate (ZDDP), an antiwear additive

The Distribution of Zinc in Low-Friction ZDDP Tribofilm on Iron Oxide
Tribology Online, 2009 To develop a low-friction and low-wear tribo-system for engine components, the authors have been studying the ZDDP tribofilm formed on iron oxide. Tribotests on iron-oxide / steel sliding pairs were performed in PAO with 1 mass% ZDDP.

Impact of Fatty Triamine on Friction Reduction Performance of MoDTC Lubrication Additive
Lubricants, 2022 The impact of a fatty triamine (Triameen YT) additive was investigated on the friction performance and stability of molybdenum dithiocarbamate (MoDTC) in the formulations containing polyalphaolefin synthetic base oil (PAO) and zinc dialkyldithiophosphate

On the Mechanism of ZDDP Antiwear Film Formation [PDF]
Tribology Letters, 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 surfaces.

Ethoxylated Amine Friction Modifiers and ZDDP [PDF]
Tribology Letters, 2019 AbstractThe influence of a series of Ethomeens (ethoxylated alkylamine organic friction modifiers) on the durability and friction of tribofilms formed by a commercial blend of primary and secondary ZDDP in sliding/rolling contact has been studied. When pre-formed ZDDP tribofilms are rubbed in Ethomeen solution, boundary friction is reduced and some of ...

Mechanism of Friction and Wear in MoS2 and ZDDP/F-PTFE Greases under Spectrum Loading Conditions
Lubricants, 2015 Two different greases formulated using MoS2 and a combination of ZDDP and functionalized PTFE (F-PTFE) were examined under spectrum loading conditions where loads, frequency, and duration of the steps were treated as variables.
