Tribological Behaviour of PVD Coatings Lubricated with a FAP− Anion-Based Ionic Liquid Used as an Additive

Lubricants, 2016
This paper studies 1-butyl-1-methylpyrrolidinium tris(pentafluoroethyl) trifluorophosphate ionic liquid ([BMP][FAP]) as a 1 wt% additive to a polyalphaolefin (PAO 6) in the lubrication of CrN and TiN PVD coatings.

Tribological synergy between classical ZDDP and innovative MoS2 and MoO3 nanotube additives at elevated temperatures; pp. 178-184 [PDF]

Proceedings of the Estonian Academy of Sciences, 2019
One of the most important drawbacks limiting the application of MoS2 nanotubes (NTs) as an oil additive is their temperature sensitivity. Recent studies showed that MoS2 NTs can be substituted by MoO3 NTs in conjunction with S-containing lubricants by ...

ZDDP Tribofilm Formation and Removal

Tribology Letters
Abstract While ZDDP tribofilm formation has been widely studied, the mechanism of ZDDP tribofilm removal during rubbing is still unclear. The study employs a ball on disc tribometer to monitor ZDDP tribofilm development in rolling-sliding, mixed lubrication conditions.

Tribological Performance of Laser‐Based Surface Textured Nonconformal Contacts

Advances in Tribology, Volume 2024, Issue 1, 2024.
The benefits of surface textures on rolling and sliding tribological contacts have been an exciting field of study over the last three decades. Laser surface texturing (LST) is a comparatively newer texturing methodology that yields repeatable precise microtextures.

Quantitative structure-properties relationship and molecular design of some anti-wear lubricant additives

South African Journal of Chemical Engineering, 2020
In-silico QSPR and MD simulation methods were adopted to effectively design new lubricant anti-wear additive compounds as an alternative to zinc dialkyl dithiophosphate (ZDDP) which was reported to contribute to environmental pollution.

Experimental Comparison of the Effect of Using Synthetic, Semi‐Synthetic, and Mineral Engine Oil on Gasoline Engine Parts Wear

Advances in Tribology, Volume 2024, Issue 1, 2024.
This paper includes the laboratory and experimental methodology used to compare the effect of using mineral, semi‐synthetic, and synthetic engine oil on the parts wear of a four‐stroke gasoline internal composition engine (ICE). Three test platforms included three engines with identical, technical, and design specifications.

Impact of Fuel Contents on Tribological Performance of PAO Base Oil and ZDDP

Lubricants, 2018
Fuel and water contents are inevitable in automotive engine oils. This study intends to investigate the impact of the addition of gasoline (3–20%) and water (1%) on the lubricating performance of synthetic base oil (PAO), with or without an anti ...

Additive Adsorption on DLC Coatings in Static and Tribological Conditions Using Neutron Reflectometry

Frontiers in Mechanical Engineering, 2019
Neutron reflectometry (NR) has proven to be an important analytical tool for investigations of the adsorption in boundary lubrication for both simple and complex additives by using either deuterated additives or the base carrier lubricant.

Mechanisms of ZDDP—An Update

Tribology Letters
Abstract 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.
