The influence of slide–roll ratio on ZDDP tribofilm formation [PDF]
, 2016 The anti-wear performance and action mecha- nisms of zinc dithiophosphate (ZDDP) have been investi- gated under various test conditions. The Mini Traction Machine–Space Layer Imaging (MTM–SLIM) is a widely used and useful method for monitoring tribofilm ...

ZDDP Tribofilm Formation and Removal
Tribology LettersAbstract 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.

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 ...

Corrosive-Abrasive Wear Induced by Soot in Boundary Lubrication Regime [PDF]
, 2016 Soot is known to induce high wear in engine components. The mechanism by which soot induces wear is not well understood. Although several mechanisms have been suggested, there is still no consensus.
