Tribology of polypropylene and Li-complex greases with ZDDP and MoDTC additives [PDF]

Tribology International, 2017
The influence of thickener and additive interactions on grease lubricating performance is examined. Polypropylene and lithium complex thickened (Li-complex) greases were tested both as neat greases and with a 2 wt% addition of ZDDP and/or MoDTC.

Unraveling the mechanism to form MoS2 lubricant layers from MoDTC by ab initio simulations [PDF]

Applied Surface Science, 2022
The morphology of molybdenum disulfide (MoS2) is a crucial aspect to ensure the functionality of this remarkable 2D-material both in electronic and tribological applications. Indeed, molybdenum dithiocarbamates (MoDTCs) can be tribochemically transformed

Fretting wear of lubricated DLC coating systems [PDF]

Frontiers in Mechanical Engineering
Diamond-like Carbon (DLC) coatings are well known for their use in protection against fretting wear due to their low friction and wear properties. DLCs are metastable, allowing them to graphitise under applied load to create a graphitic transfer layer ...

The Promise of Solid Lubricants for a Sustainable Future. [PDF]

Adv Mater
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

Wear of hydrogenated DLC in MoDTC-containing oils

Wear, 2021
Abstract This paper describes a study of the effect on MoDTC-promoted a-C:H DLC wear of adding various surface-active additives used in engine lubricants, including ZDDP, an ashless EP additive, Ca detergents, dispersants, an OFM and a PAMA, to an MoDTC solution. Tribofilms formed on wear tracks on steel were analysed using SLIM, TEM, STEM-EDX, Raman
