Abstract

Conflict regarding utilization of mineral based lubricant has been in the limelight among researchers since environment protection was affected due to the existing mineral based lubricant which is non-biodegradable, non-renewable and highly toxic. In order to overcome these problems, this study was conducted with purpose to develop a new green bio-lubricant using vegetable oil with addition of Zinc Dialkyldithiophosphate (ZDDP) to improve lubrication properties of the oil. Vegetable oil was chosen since it is biodegradable, renewable, non-toxic and also features superior lubricity than mineral oil. In this study, corn oil had been blended with different concentration of 1.50 wt%, 1.75 wt%, 2.00 wt%, 2.25 wt% and 2.50 wt% of ZDDP using direct introduction method in order to investigate the most desirable concentration of ZDDP. Samples were tested and characterized using standard laboratory test methods for determination of metal content, kinematic viscosity, coefficient of friction and wear scar diameter. From the results, it was found that the corn oil with 2.00 wt% ZDDP possess the most desirable concentration of additive added since it shows lower coefficient of friction and wear scar diameter compared to the other samples. Corn oil with 2.00 wt% ZDDP detected coefficient of friction at 0.073 and wear scar diameter at 78.87 μm. From this study, it was also discovered that the tribological performance of newly developed bio-lubricant with 2.00 wt% ZDDP is better than commercialized mineral based lubricant where corn oil with 2.00 wt% ZDDP possess 0.073 of coefficient of friction and 78.87 μm of wear scar diameter which are lower compared to SAE 15W-40 that detected coefficient of friction at 0.081 and wear scar diameter at 85.00 μm. Hence, it can be concluded that corn oil with most desirable concentration of ZDDP as green alternative lubricant has a high potential to substitute the SAE 15W-40.
