Abstract

This study has investigated the influence of ferrofluid lubrication on metal tribopairs using an indigenous Block-on-Ring tribometer as per the G77 standard. Considering the complexity of the ferrofluid-based tribosystem, the experiments were carried out based on a previously proposed level-based simplified tribosystem. It is observed that the impact of ferrofluid as an interaction parameter and magnetic field as an environmental parameter has significantly affected tribological properties, that is, ∼60% less friction and ∼74% less wear loss compared to an equivalent oil-based tribosystem. Further, it is noticed that ferritic shaft-based tribosystem lubricated with ferrofluid has better tribological characteristics compared to austenitic shaft-based tribosystem. Also, it had been that a specific testing hierarchy is followed between the performance parameters. Any changes in this testing hierarchy might affect the tribological characteristics.

铁流体润滑对金属摩擦副摩擦学性能的影响

本研究使用符合 G77 标准的本地块对环摩擦仪，研究了铁流体润滑对金属摩擦副的影响。考虑到基于铁流体的摩擦系统的复杂性，实验是根据之前提出的基于水平的简化摩擦系统进行的。实验结果表明，以铁流体作为相互作用参数和以磁场作为环境参数，对摩擦学特性产生了显著影响，即与等效的油基摩擦系统相比，摩擦力降低了 60%，磨损损失降低了 74%。此外，人们还注意到，与奥氏体轴摩擦系统相比，用铁流体润滑的铁素体轴摩擦系统具有更好的摩擦学特性。此外，性能参数之间还遵循特定的测试等级。测试等级的任何变化都可能影响摩擦学特性。

期刊介绍： The Journal of Engineering Tribology publishes high-quality, peer-reviewed papers from academia and industry worldwide on the engineering science associated with tribology and its applications. "I am proud to say that I have been part of the tribology research community for almost 20 years. That community has always seemed to me to be highly active, progressive, and closely knit. The conferences are well attended and are characterised by a warmth and friendliness that transcends national boundaries. I see Part J as being an important part of that community, giving us an outlet to publish and promote our scholarly activities. I very much look forward to my term of office as editor of your Journal. I hope you will continue to submit papers, help out with reviewing, and most importantly to read and talk about the work you will find there."
