Pin on disc tribometer is a device to determine coefficient of friction and wear rate of the different materials. There is a need to design a tribometer as per standards for different applications. This study was about designing and developing a low cost tribometer to study the wear of automotive engine materials under lubricants with nano additives. Pin on disc arrangement was designed as per ASTM standard G 99–17. The parameters that can be controlled in the test rig are load, sliding distance, sliding speed, wear track diameter, lubricant temperature, mixing time of nano additives in lubricants, mixing speed to the stirrer. Measurement of frictional force was done using load cell attached to arduino circuit. Pilot testing was done by using 0.5% of nano fly ash having Average Particle Size (APS) < 100 nm, in SAE 10 W–30 lubricant. The sliding distance, sliding speed and load were taken as 1500 m, 1.5 m/s, 15 N respectively. Wear test was conducted for three cases e.i. for dry run, with lubricant and with nano additive lubricating oils. Wear test was conducted for three replications of each category. It was found that use of nano fly ash in SAE 10 W-30 was beneficial in reducing the coefficient of friction up to 76.5% and wt. loss up to 28.9%, as compared with the specimens tested under SAE 10 W-30 base oil only. The use of nano fly ash is also a novelty of this work. No literature is available on finding the tribological properties of steels using “Nano Fly Ash”. Moreover, enhancement in tribological properties using nano fly ash as a lubricant additive revealed that it can be used as a promising candidate to increase the life of automotive components up to some extent.
