Mechanisms of MoS2 formation by MoDTC in presence of ZnDTP: effect of oxidative degradation
Wear, 2005Abstract Friction-reducing properties of MoDTC-containing lubricants have been investigated as a function of their oxidative degradation state. The oxidation test is conducted with oxygen and nitrogen oxide gases simulating aged engine oils during service.

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

MoS2 Production Mechanism of MoDTC
2012Automotive industries have strong interest in fuel economy. To enhance fuel economy, engine oils need to employ effective friction modifiers (FM). Molybdenum dithiocarbamate (MoDTC) is one of FM and superior in friction reduction performance to other FM especially in boundary lubrication regime.

Evaluation of Low Phosphorus Engine Oil Containing MoDTC
SAE Technical Paper Series, 2007<div class="htmlview paragraph">Phosphorus levels in engine oil are assumed to be lower than other oils because they cause emission catalyst poisoning. It mainly originates from zinc dithiophosphate (ZnDTP), which is an essential additive for engine oils as an antiwear agent and antioxidant. The reduction of ZnDTP in engine oils will have a great

Tribology Performance of Compound Synthetic Lubricant Containing MoDTC
Advanced Materials Research, 2013In this paper, dialkyl dithiocarbamate molybdenum (MoDTC) as a friction reducing additive was used for compound synthetic lubricant. The tribological properties of MoDTC were investigated using the MFT-R 4000-high-speed reciprocating friction and wear tester.

Tribochemical interactions between Zndtp, Modtc and calcium borate
Tribology Letters, 2000Tribochemical interactions between antiwear zinc dithiophosphate (Zndtp), friction modifier molybdenum dithiocarbamate (Modtc) and overbased detergent calcium borate (OCB) lubricant additives have been investigated. Friction tests were performed in mild wear conditions under boundary lubrication, in order to enhance tribochemical surface effects.

Synergistic Effects of MoDTC and Overbased Calcium Sulfonate Additive
Advanced Materials Research, 2013The synergetic effects of molybdenum dialkyldithiocarbamate (MoDTC) and overbased liner alkyl benzene synthetic calcium sulfonate (OBCaS) on the tribological performance of lubricant were investigated using reciprocating ball-on-disk sliding friction tester. The results showed that the two kinds of additives with a certain range of concent ration could
