shift towards bio-based lubricants. Biolubricants, which are obtained from biological sources
such as vegetable oils, animal fats, and other renewable feedstocks, have gained significant
interest in recent few years to substitute traditional lubricant base oils due to their
biodegradeability. These biodegradable and non-toxic lubricants propose the advantage of being
derived from sustainable resources, thereby minimizing the environmental and carbon footprint
associated with lubrication processes. The research work presented in this thesis was undertaken
to practically investigate and compare the wear and friction performance of a possible future
generation of an environmentally friendly bio-based lubricant as a potential replacement for
conventional engine lubricants. In this research work, Computer Controlled Friction and Wear
testing machine also called reciprocating tribometer is used for experimental testing procedure of
all the lubricants. This research work will focus on improving the tribological performance of
bio-based oils by adding Nano-additives and its performance will be compared against PAO and
simple biolubricant (WCO). The main aim and objective of this research work is to compare the
tribological performance of different lubricants including biolubricant and nano based
biolubricants at various loads like 10N, 20N and 30N and at room temperature. The nano
additives which were used in this study were Copper Oxide (CuO), Zinc Oxide (ZnO), Titanium
Dioxide (TiO2), and Molybdenum Disulfide (MoS2). Tribological performances of all lubricants
were compared to check which lubricant reduce friction and wear and give better COF. After all
the testing procedure, comprehensive wear analysis performed through digital 3D Olympus
microscope to quantify wear volume, depth, and the identification of wear types such as abrasive
and adhesive wear. Additionally, high-resolution scanning electron microscopy (SEM) imaging
is used to examine the tribofilm formation, wear patterns, and surface scars at microstructural
levels. In the end, Energy-Dispersive X-ray Spectroscopy (EDS) was employed for elemental
analysis and compositional explanation on sample surface after the testing.
