Kinetic Study on Lubricity of MoDTC as a Friction Modifier

open access: yesTribology 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 Temperature on Lubrication Property with MoDTC-Containning Lubricant

open access: yesTribology Online, 2018
The effect of temperature on the lubricity of molybdenum dithiocarbamate (MoDTC) was investigated by a ball on disk tribometer with lubricant oil containing MoDTC and calcium sulfonate (CaSU) at temperatures of 25˚C, 40˚C, 60˚C and 80˚C.

The Promise of Solid Lubricants for a Sustainable Future. [PDF]

open access: yesAdv Mater
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

Se Nanopowder Conversion into Lubricious 2D Selenide Layers by Tribochemical Reactions

open access: yesAdvanced Materials, Volume 35, Issue 42, October 19, 2023., 2023
A simple sprinkling of Se nanopowders onto sliding Mo and W thin films leads to the tribochemical in operando formation of lubricious 2D selenides. Due to the thermal and vacuum stability of the Se nanopowders they can be used to replenish sliding components with solid lubricants, avoiding the long‐lasting problem of transition metal ...

Energy‐Conserved Hydrodynamic Lubricated Components with Wall Slippage

open access: yesInternational Journal of Rotating Machinery, Volume 2023, Issue 1, 2023., 2023
The hydrodynamic thrust slider and journal bearings as well as hydrodynamic lubricated gears with the merit of energy conservation by the wall slippage are reviewed. The principle for designing these hydrodynamic contacts is to artificially set the wall slippage on the stationary surface in the hydrodynamic inlet zone.

Influence of NO x and Air on the Ageing Behaviour of MoDTC [PDF]

open access: yesTribology 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.

A methodology for Raman characterisation of MoDTC tribofilms and its application in investigating the influence of surface chemistry on friction performance of MoDTC lubricants [PDF]

open access: yesTribology Letters, 2015
In this study, Raman spectroscopy has been employed to understand the influence of surface chemistry on friction in a tribocontact. Tribotests were conducted using molybdenum dialkyldithiocarbamate (MoDTC) lubricant in a steel/steel sliding contact. Firstly, surface chemistry in the high-friction regime, at the beginning of the test, and in the low ...

Wear Mechanisms of Hydrogenated DLC in Oils Containing MoDTC [PDF]

open access: yesTribology 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 ...

Formation mechanisms of zinc, molybdenum, sulfur and phosphorus containing reaction layers on a diamond‐like carbon (DLC) coating Bildungsmechanismen von zink‐, molybdän‐, schwefel‐ und phosphorhaltigen tribochemischen Reaktionsschichten auf einer diamantähnlichen Kohlenstoffbeschichtung (DLC)

open access: yesMaterialwissenschaft und Werkstofftechnik, Volume 51, Issue 7, Page 1009-1030, July 2020., 2020
Tribochemical reactive formed layers on diamond‐like carbon (DLC) after tribological testing were analyzed. Hereby, the formation of zinc, molybdenum, sulfur and phosphorus containing reaction layers could be identified using Raman spectroscopy and scanning electron microscopy.
