| Summary: | Lubrication is an essential tool in human life. As the technology advances, the method of
lubrication becoming a lot complex and we relied heavily on mineral oil or synthetic oil
which are harmful for the environment. Researchers around the world have started to shift
their focus on bio-lubrication that is more environmentally friendly. Bio-lubricant based
on palm oil could be one of the best replacements of standard lubricant. With nanoparticle
additives, the tribological performance of the bio-based lubricant could be improved even
more. This investigation will be centred around the tribological characteristic of bio based
trimethylolpropane (TMP) ester with nanoparticle and nanocomposite additive. Additives
that in focus are Copper Oxide (CuO) and Titanium Dioxide (TiO2). The nanocomposites
are the mix of both nanoparticles with different configuration ratio. The aim of the
investigation is to obtain the tribological performance of all the targeted samples and
compare it to understand the best sample in term of tribology. It is found that the bio
based TMP ester have tribological potential against the conventional PAO8. For
nanoparticles, Copper Oxide shown that the concentration of 0.1 wt.% produced the best
tribological performance against other tested concentration. Titanium Dioxide
nanoparticle with concentration of 0.1 wt.% also produced the best tribological
performance against other tested concentration. For nanocomposite, it found that the
configuration ratio of 1 Copper Oxide to 2 Titanium Dioxide yields the best tribological
performance against other tested configuration ratios. |
