Ze Liu, Zhijun Yan, Shibo Wu, Haocheng Sun, Shengwei Zhang
TL;DR
This study explores how magnetic ionic liquid additives affect friction and lubrication in oils, showing reduced wear and improved performance under magnetic fields.
Contribution
A new mixed lubrication model incorporating boundary film strength and magnetic additives is proposed for better tribological analysis.
Findings
Magnetic additives significantly reduce friction and wear, especially under magnetic fields.
The boundary film strength model accurately captures lubrication state transitions.
The mixed lubrication model improves prediction of tribological behavior in friction pairs.
Abstract
In this paper, the tribological characteristics of an oil-soluble magnetic fluid additive under mixed lubrication are studied by experiments and numerical simulation. [bmim][FeCl4] is dissolved in CF10W-40 lubricating oil as a magnetic liquid additive, and its friction coefficient is tested by a point contact friction tester at different temperatures, rotational speeds and magnetic field intensities. The transition condition of lubrication state is obtained through analyzing the Stribeck curves based on the experiments, and the strength model of boundary film is established accordingly. A mixed lubrication model is established by substituting the boundary film strength model and the surface roughness model into the hydrodynamic lubrication model based on Reynolds equation. The results show that the magnetic solution as an additive can obviously reduce friction and wear, and the effect…
