Formation of Nano Interface by Sliding between Hard Coatings and Metals in MoDTC Contained Oil
Tribology Online, 2022 The viscosity of motor oil gets lower in order to decrease resistance at region of the fluid lubrication. On the other hands, this causes increasing of friction at the boundary lubrication region.

Synergistic Effects of MoDTC and ZDTP on Frictional Behaviour of Tribofilms at the Nanometer Scale [PDF]
Tribology Letters, 2004 The layered structure and the rheological properties of anti-wear films, generated in a rolling/sliding contact from lubricants containing zinc dialkyldithiophosphate (ZDTP) and/or molybdenum dialkyldithiocarbamate (MoDTC) additives, have been studied by dynamic nanoindentation experiments coupled with a simple modelling of the stiffness measurements ...

Tribochemistry and EP Activity Assessment of Mo‐S Complexes in Lithium‐Base Greases
Advances in Tribology, Volume 2008, Issue 1, 2008., 2008 The blends of bis(1,5‐diaryl‐2,4‐dithiomalonamido)dioxomolybdenum(VI) complexes in lithium‐base grease are evaluated for their extreme pressure activity in a “four‐ball test” using 12.7 mm diameter alloy steel ball specimen. The additive, bis(1,5‐di‐p‐methoxyphenyl‐2,4‐dithiomalonamido)dioxomolybdenum(VI) and bis(1,5‐di‐p‐chloro‐phenyl‐2,4 ...
