Study and Investigation of Tribological Functions of Nano Additive With Sae 40/W20 Oil on En 19

Abstract

High operating conditions of moving machine components leads various wearing and failure mainly due to friction. Lubricants are widely used to overcome the friction of the components. Poor performance of lubricant plays a significant energy and material losses. Hence the lubricant needs to synthesis for desirable high working conditions. When the Nano particles introduced into the lubricant matrix, it adheres on one of the moving parts and changes sliding friction to rolling friction resulting in reduced friction losses, wear and increased life of bearing. This research focuses on usage of SAE 40/w20 oil as a lubricant with addition of Multi Walled Carbon Nano Tubes (MWCNTs) as Nano particles. Ultrasonic agitator and Pin on Disk apparatus were used for testing of material EN 19. This study concluded that addition of MWCNTs to the lubricating oil results in considerable decreases in friction, wear rate and increases the load carrying capacity of the lubricant. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
