Physiochemical Properties of Hexagonal Boron Nitride Blended Coconut Oil

Abstract

Lubrication plays a vital role in engineering. Now a day’s reduction in friction is a major and ongoing task for researchers. Few researches are focussing on various Nano additives that lower value of friction and hence wear can be reduced. Therefore, the main objective of this paper is to determine the anti-wear characteristics of the lubricant along with extreme pressure point. Further, also determine the physiochemical properties. In this research coconut oil is used as a lubricant and hexagonal boron nitride (h-BN) is used as friction modifier. The ultrasonic homogenizer was used for mixing of friction modifier with lubricant. Further, four ball test rig was used to obtain the extreme pressure, coefficient of friction and wear scar. After test, balls were characterized using 3D optical profilometer and scanning electron microscopy. From the results, it is observed that 2.5 wt % h-BN with coconut oil gives low coefficient of friction, high extreme pressure with moderate wear scar. Finally, Comparison with commercial mineral oil (CMO), the newly developed additive oil combination is having excellent properties and it can be used as a substitute as it is biodegradable, nontoxic, easily manufactured and environment friendly.
