Abstract

The demand for an alternative lubricant and concern to the environmental issues prompted this study to develop a new bio-lubricant based on vegetable oil. However, the performance of vegetable oil as lubricant oil is ineffective because of producing high friction on the surface. In this study, the commercialized corn oil was mixed with additives of Zinc dialkyldithiophosphate (ZDDP) and Molybdenum dialkyldithiophosphate (MoDTP) as to improve the physical and tribological properties of oil. The commercial cooking corn oil was selected as the base oil and mixed with 2wt% ZDDP and added with 0.00wt%, 0.05wt%, 0.10wt%, 0.15wt% and 0.20wt% MoDTP. The samples were tested using Rotating Disc Electrode Atomic Emission Spectroscopy (RDE-AES) and Kittiwake Heated Viscometer while characterize using Four Ball Tester and Upright Light Microscope to investigate the coefficient of friction and wear scar diameter. The addition of 2wt% ZDDP and 0.05wt% MoDTP into corn oil gives the desired result where the kinematic viscosity value at 36.20 cSt and lowest coefficient of friction at 0.074. This mixture also demonstrated lowest wear scar diameter at 74.35 μm compared to the other samples. In conclusion, the newly bio-lubricant has successfully developed by adding ZDDP and MoDTP into corn oil as a substitute for commercial mineral lubricant oil.
