Abstract

Different kinds of lubricants are obtainable all around the worldwide including mineral oils, synthetic oils, re-filtered oils, and vegetable oils. Mostly the lubricants that obtainable in the wholesale place are mineral oil extrated from petroleum oil in which that is not acceptable with the environment because of toxicity and low biodegradability ability. The use of vegetable oil as a lubricant has stimulated the interest of academics due to diminishing petroleum sources and environmental concerns. In comparison to mineral-based oils, vegetable-based lubricants have better real properties, corrosivity, and are limitless and biodegradable. Virgin biological oil or refined agricultural wastes may be used as a resource of bio-based lubricants. This thesis examined the virgin vegetable oil follow by utilizing the nanoparticles that used as additives to obtain an excellent tribology properties that can improve bio-based lubricants. This research found the nanoparticle that meet the basic requirement types and concentrations, then examine and find out the most suitable that can enhance wear protection and reduce friction. Hexagonal boron nitride (hBN) nanoparticles in place of lubricant additive was added into the vegetable oil to improve its physical and tribology properties. Four-ball-wear tests were completed on the extraction of vegetable oil along with the addition of hexagonal boron nitrate nanoparticles lubricated to each of the contact surface. As a results, nanoparticles improved the physical properties along with the good anti-wear and anti-friction characteristics of the lubricant mixtures comparing to the mineral oil. Vegetable oil have meet the basic criteria as bio-based lubricant and can replace the mineral oil as a new advanced renewable bio-based lubricant for industrial activities that concern to the environment and save cost.
