Abstract
In this thesis, an investigation of tribological properties of bio-lubricant with 𝑇𝑖𝑂2 nanoparticles and comparison between synthetic lubricant in the market is studied. In general, wear is a process where the material is removed from two surface contact of solid whether the motion of the contact is in rotation or sliding motion. To reduce wear, bio-lubricant with 1 wt. % of 𝑇𝑖𝑂2 is used for lubrication to reduce wear and friction between surface contacts. There are two experiments which are Pin-on-Disc and Four-Ball wear test that will be done with tribological parameters such as normal load, sliding distance, disc rotation speed, time, sliding distance and temperature. Wear mechanism are also studied in 2D simulation using ABAQUS software. Surface morphology of respective experiments are analysed by using SEM machine and microscopic machine. Results shows that Palestine Olive Oil with 1 wt.% 𝑇𝑖𝑂2 tribological performances, in term of wear and COF, are better than Palm Oil with 1 wt.% 𝑇𝑖𝑂2 while Synthetic SAE5W40 overall performance outmatch those bio-lubricants with 𝑇𝑖𝑂2 nanoparticles. Further works in varying concentration of 𝑇𝑖𝑂2 nanoparticles and temperature in Four-Ball wear test are needed to be done to find the suitable compatibility of 𝑇𝑖𝑂2 nanoparticles with bio-lubricant.
