In this study, nanofly ash was used as an additive in SAE 10W-30 lubricant oil to investigate the tribological properties of modified oil on AISI 4140 steel using an indigenously developed pin-on-disk wear testing setup. Cylindrical pins of AISI 4140 were prepared to wear test the specimens: (a) in dry conditions, i.e., without lubricating oil and without nanofly ash, (b) with lubricating oil, and (c) with lubricating oil + 0.5 wt% nanofly ash. Specimens tested under lubricating oil + 0.5 wt% nanofly ash exhibited excellent wear resistance properties of AISI 4140 steel. Preliminary studies revealed that the use of nanofly was beneficial in reducing the coefficient of friction up to 76.5% and wt loss up to 28.9%, when compared with the specimens tested under SAE 10W-30 base oil only.

在这项研究中，纳米粉煤灰用作SAE 10W-30润滑油的添加剂，使用本地开发的销盘磨损试验装置研究了AISI 4140钢上改性油的摩擦学性能。准备AISI 4140的圆柱销以对样品进行磨损测试：（a）在干燥条件下，即无润滑油和无纳米粉煤灰;（b）有润滑油的;和（c）有润滑油+ 0.5 wt％纳米粉煤灰。在润滑油+ 0.5 wt％的纳米粉煤灰下测试的样品显示出AISI 4140钢的优异耐磨性能。初步研究表明，与仅在SAE 10W-30基础油下测试的样品相比，使用纳米蝇有助于降低摩擦系数高达76.5％和重量损失高达28.9％。
