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

Wear Mechanisms of Hydrogenated DLC in Oils Containing MoDTC [PDF]
Tribology Letters, 2016 Diamond-Like Carbon (DLC) coatings are well known for offering excellent tribological properties. They have been shown to offer low friction and outstanding wear performance in both dry and lubricated conditions. Application of these coatings for automotive components is considered as a promising strategy to cope with the emerging requirements ...

Influence of Soot on the Anti-Wear Property of MoDTC and ZDDP [PDF]
Cailiao Baohu, 2022 In order to investigate the influence of soot on the anti-wear property of molybdenum dialkyldithiocarbamate(MoDTC) and zinc dialkyldithiophosphate(ZDDP), the soot was added into different oil samples and then a four-ball machine friction experiment was ...

Influence of NO x and Air on the Ageing Behaviour of MoDTC [PDF]
Tribology Letters, 2017 Molybdenum dialkyldithiocarbamates (MoDTCs) are very effective friction modifier additives for use in engine oils and other lubricants. However, as engine oils age during extended drain intervals, MoDTCs can lose some or all of their ability to reduce friction and this is generally believed to result from their oxidative degradation.

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.

Analysis of Wear Track on DLC Coatings after Sliding with MoDTC-Containing Lubricants
Tribology Online, 2017 Wear of DLC coating has been great concern in DLC/Steel sliding surface lubricated by molybdenum dithiocarbamate (MoDTC) containing lubricants. However, in order to design lubrication system with DLC and MoDTC, the mechanism of this issue is needed to be

Kinetic Study on Lubricity of MoDTC as a Friction Modifier
Tribology Online, 2019 The temperature dependence of friction coefficient of lubricant oils containing MoDTC was evaluated using a ball on disk tribometer at constant temperatures of 25, 40, 60 and 80°C.

The Effect of Combustion on Modtc Friction Reduction Capabilities Determined by Engine Tests
Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering TribologyMolybdenum Dithiocarbamate (MoDTC) is an excellent friction modifier used in oil formulations for internal combustion energies. In the search of minimising transition metals contents in lubricating oils, extensive work has been carried out in benchtop tribometers to produce optimised formulations.
