Effect of nano-additives on friction and wear characteristics of blended lubricants containing "palm oil and Al-Rashid engine oil SAE 15W_40"

Abstract

The research aims to evaluate the nano-additives for oil, decreasing friction, surface roughness, and decreasing wear.Wear and friction coefficient are examined using a pin on a disk device; adding 2 wt.% nano-additives to the blended lubricant resulted in maximum friction and wear.In the current research, one of the more significant findings to emerge from this study is that the nano-additives increase viscosity and reduce wear and friction coefficient. The highest viscosity values were when adding GNP, and improving the percentage of nano-additives leads to an increase in viscosity.The results reveal that the additive was chosen as the most appropriate concentration in the blended lubricant.An experimental investigation was conducted to explore the effects of nano-additive graphene nano-powder (GNPs), molybdenum disulfide (MoS2), and titanium oxides (Tio2) in concentrations (0.5%,1%, 1.5%, 2%,2.5% ) as additives to engine oil (Al-Rashid oil) SAE 15W_40 and 5% palm oil.The results presented in the given paper may facilitate improvements in the nano-additives, resulting in increased viscosity compared to the base oil.
