Tribochemical reaction and wear mechanism of MoDTC based friction modifier

Tribology International, 2022
Abstract In this study, molybdenum dithiocarbamate (MoDTC) coatings were fabricated on 304 stainless steel substrates via an electrodynamic spraying process with the aim to clearly understand the evolutionary process from MoDTC to MoS2 during contact sliding. Experiments were performed using an in-situ tribo-tester equipped with Raman spectroscopy to

ZDDP and MoDTC interactions in boundary lubrication—The effect of temperature and ZDDP/MoDTC ratio

Tribology International, 2006
Abstract Tribofilms formed under boundary lubrication from ZDDP and MoDTC additives alone or in different ratios in the lubricant have been studied. The tribological performance is linked to the tribofilm properties and consequently to the lubricating conditions. Tribofilms are formed using a reciprocating pin-on-plate tribometer.

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.

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
