EXPERIMENTAL INVESTIGATION ON THE TRIBOLOGICAL PROPERTIES OF LUBRICANT OIL WITH NANO-PARTICLE ADDITIVES
The present work aims in understanding the tribological properties of lubricant oil with additives such as SiO2, TiO2, and Al2O3 as nano-particles. For tribological applications, the nano-particles were added into lubricating oil to improve extreme pressure, anti-wear and friction reduction properties. Samples are prepared by adding different proportion of additives in the oil and their properties were evaluated. The nano-particles dispersion was carried out carefully and their properties such as flash and fire point, viscosity, density and pour point are tested. The friction and wear experiments were performed using pin-on-disc tribotester. From the experimental results it has been inferred that, the mixing of SiO2, TiO2 and Al2O3 nano-particles as additives in engine oil improves the lubricating oil properties and significantly reduces the friction and wear rate. Thus, it is evident from the experimental studies the addition of nano-particles reduces friction and improves the anti-wear properties of the lubricating oil. The results of the tests obtained from the blend show that the most important properties such as viscosity, density, flash point, increases with increase in additive concentration. It is recommended that additives should be used to achieve the desired properties of the engine oil for enhanced engine performance.
