New insights on the decomposition mechanism of Molybdenum DialkyldiThioCarbamate (MoDTC): a Raman spectroscopic study [PDF]
, 2016 Molybdenum DialkyldiThioCarbamate (MoDTC) is a friction modifier that has been used in automotive engines for many years. However, its exact decomposition mechanism within tribocontacts is not fully understood.

Enhanced Growth of ZDDP-Based Tribofilms on Laser-Interference Patterned Cylinder Roller Bearings
Lubricants, 2017 Laser surface texturing has been successfully applied in the past to various machine elements in order to improve their tribological performance. In this study, direct laser interference patterning was used to produce periodic cross-like surface patterns

FAP- Anion Ionic Liquids Used in the Lubrication of a Steel–Steel Contact [PDF]
, 2013 This study compares the tribological behavior of two ionic liquids ([BMP][FAP] and [(NEMM)MOE][FAP]) used as oil additive for the lubrication of a steel–steel contact. Friction and wear experiments were performed using a HFRR test machine.

Tribology LettersAbstract This paper describes how research over the last 20 years has advanced our understanding of the mechanisms of action of ZDDP, especially with respect to tribofilm formation. We now know that ZDDP tribofilm formation is promoted by applied shear stress and this explains many of the features of these films.

Design of novel experimental techniques to investigate the formation of nanoparticle-based tribofilms [PDF]
, 2006 Nano-engineered lubricant additives such as organically-active nanoparticles of molybdenum disulphide (Hybrid-milled MoS2) are becoming increasingly popular in the fight against harsh friction and wear that occurs during boundary-layer lubrication.
