Understanding the wear behaviour of non-doped and Si,O-doped diamond-like carbon films [PDF]
Two diamond-like carbon coatings have been examined, both prior to, and post tribotesting. Physical–chemical characterisation allows the elucidation of both the physical and tribochemical mechanisms underpinning the respective wear behaviours.

Tribological Performance of Laser‐Based Surface Textured Nonconformal Contacts
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.

Effect of steel hardness on soot wear
Due to incomplete combustion, high levels of soot can accumulate in engine lubricants between drain intervals. This soot can promote wear of engine parts such as timing chains and cam followers.

ZDDP Tribofilm Formation and Removal
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.

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.

Friction and wear response of vegetable oils and their blends with mineral engine oil in a reciprocating sliding contact at severe contact conditions [PDF]
Although many studies investigating the tribological performance of pure vegetable oils have been conducted, a better understanding of vegetable oil tribological performance at extreme conditions is still needed. Similarly, little work has been carried

Tribochemical Manufacturing of Thin Functional Films on Silicon Oxide Surfaces
The discovery of tribochemical reactions at the sliding interfaces has suggested new pathways for material synthesis. This study explored the formation of thin functional films at the steel-on-silicon sliding interfaces, with toluene as base liquid and ...

The impact of organic friction modifiers on engine oil tribofilms
Organic friction modifiers (OFMs) are important additives in the lubrication of machines and especially of car engines where performance improvements are constantly sought-after. Together with zinc dialkyldithiophosphates (ZDDPs) antiwear additives, OFMs

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