In recent years, studies have shown that using nanoparticles (NPs) as lubricant additives lead to the enhancement of the anti-wear behaviour of oils. In this study, the anti-wear behaviour of silver (Ag) NPs which were capped with polyvinyl alcohol and sodium citrate were investigated for three different sliding speeds (2, 3 and 4 mm s⁻¹) under two different loads (30 and 50 N). Results show that the AgNPs led to a decrease in friction and wear due to the formation of a tribofilm and a rolling effect. However, influence of the AgNPs declined at higher loads while increasing at higher speed test conditions. Also, both stabilising agents underwent disordering of AgNPs morphology and size successively under the applied loads.

近年来，研究表明，使用纳米颗粒 (NPs) 作为润滑油添加剂可以增强油的抗磨性能。在这项研究中，将其封端的聚乙烯醇和柠檬酸钠银的抗磨损性能（Ag）的纳米颗粒进行了研究了三种不同的滑动速度（2,3和4mm小号^-1两个不同的负载（30和50下）否）。结果表明，由于形成摩擦膜和滚动效应，AgNPs 导致摩擦和磨损的减少。然而，AgNPs 的影响在更高的负载下下降，而在更高的速度测试条件下增加。此外，两种稳定剂在施加的载荷下相继发生了 AgNPs 形态和尺寸的无序化。
