Influence of ZDDP tribofilm on micropitting formation and progression

Tribology International
This paper presents insights into how Zinc Dialkyl Dithiophosphate (ZDDP) influences the formation and progression of micropitting. Experimental investigations were conducted using a twin-disc tribometer in rolling-sliding contacts under mixed or boundary lubrication conditions, focusing on the impact of ZDDP on micropitting in bearing steel samples ...

Simulation scheme for investigating the wear protection effect of a ZDDP tribofilm

An initial idea is presented on how the wear protection of a ZDDP tribofilm can be investigated numerically. Since wear protection is based on the equilibrium of tribofilm removal and tribofilm formation, both processes are modelled and then combined in ...

Oxidation-regulated wide-temperature tribological behavior and mechanism of a Mo/Mo tribopair lubricated by Ga-based liquid metal

iScience
Summary: Gallium-based liquid metals combine fluidity with high thermal and electrical conductivity, making them attractive for lubrication in demanding environments. We investigated the tribological behavior of a Mo/Mo self-mated pair lubricated with Ga-

Protective Tribofilms on Combustion Engine Valves

, 2018
Inside the complex machinery of modern heavy-duty engines, the sealing surfaces of the valve and valve seat insert have to endure. Right next to the combustion, temperatures are high and high pressure deforms the components, causing a small relative motion in the interface.

Stable Friction of Phenolic Composites Enabled by Tribofilm under Dry-Wet Alternating Conditions

Achieving stable friction and ultra-low wear within braking systems under dynamically alternating drywet conditions remains a formidable challenge. Herein, nanoSiC and ZrO2 are incorporated into an abundant-BaSO4-filled phenolic resin (PF) to construct ...
