In Situ Raman-SLIM Monitoring for the Formation Processes of MoDTC and ZDDP Tribofilms at Steel/Steel Contacts under Boundary Lubrication

open access: diamondTribology Online, 2020
In this study, the formation processes of molybdenum dithiocarbamate (MoDTC) and zinc diallyldithiophosphate (ZDDP) tribofilms were investigated using an in situ Raman-space layer imaging method (SLIM) tribometer under boundary lubrication.

The Effect of UV Irradiation to a-C:H on Friction and Wear Properties under PAO Oil Lubrication Including MoDTC and ZnDTP

open access: diamondTribology Online, 2018
One of the solutions to reduce friction between two sliding surfaces in automobile engine is by applying DLC coating to engine components. However, it is critical that the effect of lubricant additives to DLC coating to be clarified before hands as to ...

Unraveling the mechanism to form MoS2 lubricant layers from MoDTC by ab initio simulations

open access: hybridApplied Surface Science, 2022
The morphology of molybdenum disulfide (MoS2) is a crucial aspect to ensure the functionality of this remarkable 2D-material both in electronic and tribological applications. Indeed, molybdenum dithiocarbamates (MoDTCs) can be tribochemically transformed into MoS2, which is able to reduce the friction coefficient of metallic moving parts. However, this

MoDTC lubrication of DLC-involving contacts. Impact of MoDTC degradation [PDF]

open access: yesWear, 2016
Abstract Recently Diamond-Like Carbon (DLC) coatings have attracted considerable attention due to their low friction, high hardness, good wear and corrosion resistance, and high thermal and chemical stability. Although considerable research has been conducted on the effect of molybdenum-based additives, e.g., molybdenum dithiocarbamate (MoDTC), on ...

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.
