Behaviour of MoDTC in DLC/DLC and DLC/steel contacts

Tribology International, 2012
Abstract Diamond-like carbon (DLC) coatings are beginning to be used on machine components parts because of their excellent friction and wear resistance properties. It is hence important to be able to formulate lubricants able to work effectively with these coatings.

Tribological interactions between TiN PVD coating and MoDTC under boundary lubrication conditions

Vacuum, 2022
Abstract In this study, the tribological performances of steel/steel and steel/TiN coating systems are investigated under the condition of boundary lubrication by a PAO base oil containing various concentrations of MoDTC. Additionally, the effects of the MoDTC concentration and the contact pressure on the tribochemical decomposition reaction of MoDTC

Ageing impact on tribological properties of MoDTC-containing base oil

Tribology International, 2015
Abstract Since last decades, there is an industry-wide need for the comprehension of how degradation affects lubricant tribological performance. The lubricating performances of MoDTC-containing base oil, fresh and aged, have been assessed using reciprocating tribometer, and XPS and TEM have been used to characterize the tribofilm formed.

Boundary lubrication mechanisms of carbon coatings by MoDTC and ZDDP additives

Tribology International, 2005
Abstract Fuel economy and reduction of harmful elements in lubricants are becoming important issues in the automotive industry. An approach to respond to these requirements is the potential use of low friction coatings in engine components exposed to boundary lubrication conditions.

Hydrogen influence on material interaction with ZDDP and MoDTC lubricant additives

Wear, 2013
Abstract In this paper the interaction of lubricant additives with hydrogen at the frictional interface has been investigated. Three different states of the base AISI 52100 alloy steel have been tested: untreated, nitrided and sulphonitrided, with different combinations of PAO6 base oil and ZDDP/MoDTC (Zinc DialkylDithioPhosphate and Molybdenum ...

Boundary Lubrication Mechanisms of Molybdenum Film by MoDTC and ZDDP Additives

Applied Mechanics and Materials, 2015
Molybdenum (Mo) film is deposited by Ion Beam Assisted Deposition (IBAD) on the 316L steel substrate surface in this experiment. The micro structure and nanohardness of the film are tested by Scanning Electronic Microscope (SEM) and nanoindentation tester.

Study Tribological Properties of MoDTC and Its Interactions With Metal Detergents

Journal of Tribology, 2020
Abstract Recently, the synergistic tribological properties between molybdenum dialkyldithiocarbamate (MoDTC) and metal detergents have been the focus of significant attention due to the high requirements of engine oil. In this study, an SRV tribometer and four-ball machine were used to study the tribological performance of MoDTC combined

In situ Raman observation of structural transformation of diamond-like carbon films lubricated with MoDTC solution: Mechanism of wear acceleration of DLC films lubricated with MoDTC solution

Tribology International, 2017
Abstract The structural transformation of a hydrogenated amorphous carbon (a-C:H) film lubricated with MoDTC solution was investigated using a laboratory-built in situ Raman tribometer. Especially, we aimed to reveal the wear acceleration of DLC films lubricated with MoDTC solution. All our results suggest that the main reasons of wear acceleration
