| Summary: | The excessively use of petroleum-based oil as a
metalworking fluid is hazardous to the worker and cause
a pollution to the environment. As a result,
environmentally friendly oil has gradually replaced
petroleum-based oil in the machining process. The goal of
this study is to investigate the tribological enhancement of
modified jatropha oil (MJO) by activated carbon
nanoparticle (AC) ranging from 0.01 to 0.05 wt.% through
the four-ball test and turning process. The results reveal
that MJO with 0.025wt% AC nanoparticle has exceptional
tribological performance in terms of friction and wear,
resulting in extended tool life in terms of machining length
(7000mm) and machining time (49 minutes). The
addition of 0.025wt.% AC nanoparticle created a
protective layer that facilitates rolling action at the sliding
surfaces. As a result, MJO with 0.025wt% AC has excellent
tribological properties, making it a viable alternative as an
environmentally friendly metalworking fluid. |
