AMALGAMATION, PORTRAYAL AND EFFICACY OF HELIANTHUS ANNUUS BIO LUBRICANT WITH NANO ADDITIVE

Abstract

Owing to the hazardous contribution towards environment from mineral oil-based lubricants, bio-degradable lubricants extracted from vegetable oils seems to be a promising candidate considering climate change, energy security and green environmental approach. In this research work, chemically modified helianthus annuus is considered as a viable option due to its excellent tribological properties and considerable polyunsaturated fatty acid. To further enhance the tribological properties, copper oxide nanoparticles were added to the base oil in varying proportions of 0.2, 0.3 and 0.5% by weight fractions. The application of nano enhanced biolubricants on worm and gearbox is studied. The addition of copper oxide nanoparticles enhances dispersion stability of the biolubricant. Tribological characterization was conducted using pin-on disc machine. Tribological properties such as coefficient of friction and wear rate along with kinematic viscosity is analysed for each composition. The obtained results are compared with synthetic oil SAE 75. It is observed that with the inclusion of copper oxide nanoparticles to the biolubricant, there is a notable decrease in wear rate along with lower friction coefficient.
