Abstract
Friction and wear are one of the main factors that affect the efficiency, performance, quality and life span of machinery system. The purpose of this study is to determine the friction and wear properties of natural oil-based lubricant which consist of refined glycerin, crude glycerol and oleic methyl ester to compare with the friction and wear properties of commercial lubricant. Four ball tester experiments are carried out based on ASTM standard to evaluate the tribology properties of lubricants. The measurements of Coefficient of Friction and Wear Scar Diameter are taken at bearing ball for different types of lubricants. The difference in coefficient of friction and wear scar diameter for lubricant with and without additive and different temperature are being investigated. The results obtained from physical measurement and analysis is compared with coefficient of friction and wear scar diameter of commercial lubricants. The average coefficient of friction obtained from analysis for refined glycerin and crude glycerol with and without additive show lower reading compared to commercial lubricant. Lubricant with Carbon Nano Tube as additive show more preferred result compare to lubricant without additive in term of coefficient of friction. With the increase in temperature, the coefficient of friction for lubricant for both with and without additive increased. For wear scar diameter, performance of natural oil-based lubricant with and without additive, high and low temperature show better result compare to commercial lubricants. Overall, for coefficient of friction, at temperature of 75◦C refined glycerin shows the most preferable result and at the temperature of 85◦C, crude glycerol without additive shows the most preferable result. For wear scar diameter, at low and high temperature, refined glycerin without additive show the smallest reading compare to other. Based on the result, recommendations and suggestions are made to improve the accuracy of tribology test and tribology properties of lubricants.
