摘要

矿物油基润滑油因其有益的性能而得到了广泛的应用。然而，它们对环境的影响和毒性引起了人们的关注，从而促使人们寻找可持续和环境友好的替代品。本研究考察了棕榈油基润滑脂在添加铜纳米颗粒浓度为0.25和0.50 wt%时的摩擦学行为。使用四球摩擦计进行了摩擦磨损试验，以评估配方润滑脂的性能，并将其与商用矿物润滑脂进行比较。结果表明，添加0.25 wt%纳米铜颗粒的棕榈油基润滑脂具有优异的润滑性能，具有低摩擦和防磨损特性。与纯棕榈油基润滑脂相比，该浓度的Cu纳米颗粒使平均摩擦系数(COF)降低35.05%，磨损疤痕直径(WSD)降低32.56%，磨损体积减少48.02%。

The tribological performance analysis of palm olein-based grease lubricants containing copper nanoparticle additive

Mineral oil-based lubricants have been widely used for their beneficial properties. However, their environmental impact and toxicity have raised concerns, resulting in a search for sustainable and environmentally friendly alternatives. This study investigates the tribological behavior of palm olein-based grease with copper nanoparticles additive concentrations of 0.25 and 0.50 wt%. The friction and wear tests were conducted using a four-ball tribometer to evaluate the performance of the formulated grease and compare it with commercial mineral grease. The results showed that the palm olein-based grease with a 0.25 wt% copper nanoparticle additive concentration had excellent lubricant performance, with low friction and wear prevention characteristics. This concentration of Cu nanoparticles led to a 35.05% reduction in average friction coefficient (COF), a 32.56% reduction in wear scar diameter (WSD), and a 48.02% reduction in wear volume compared to pure palm olein-based grease.

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."
