Abstract
Micro pitting and wear are one of the most common phenomena in gear parts
where it becomes the thing that causes machine damage. The damage to this machine
will have a very big impact because it requires an engineer to repair the damaged
machine parts and it consumes a relatively high cost even though the damage faced by
the gear parts is only small - scale. Proper lubrication is crucial to avoid gear failure.
It is necessary to identify the influence of lubricants on the dispersion and wear of
micro pitting, as well as to identify any significant influences that may occur when
additives are applied to samples. The main purpose of this study was to study the micro
pitting and wear behaviours of palm oil base grease in spur gear and to evaluate the
performance of biodegradable grease compared with and without nanoparticle MoS2
as an additive. In this study, the experiment is carried out using a gear test rig and the
test is run under three different conditions. Surface scanning was done to evaluate the
gear surface profiles. The finding shows that the gear lubricated with palm oil grease
with MoS2 additive has less micropitting depth and wear. This indicates that the
additive manages to reduce the surface damage efficiently and is compatible with the
palm grease.
