A methodology for Raman characterisation of MoDTC tribofilms and its application in investigating the influence of surface chemistry on friction performance of MoDTC lubricants [PDF]
Tribology Letters, 2015 In this study, Raman spectroscopy has been employed to understand the influence of surface chemistry on friction in a tribocontact. Tribotests were conducted using molybdenum dialkyldithiocarbamate (MoDTC) lubricant in a steel/steel sliding contact. Firstly, surface chemistry in the high-friction regime, at the beginning of the test, and in the low ...

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 ...
