Newly developed lubricant was
produced by introducing Zinc Dialkyldithiophosphate
(ZDDP) into commercialized corn oil. ZDDP added
acted as a physical property improver which lowers the
kinematic viscosity and reduces coefficient of friction.
The newly developed oil was tested with a kinematic
viscometer while characterized using a pin on disc
tribometer. Corn oil with 2 wt% ZDDP and 5 wt%
ZDDP showed a decreasing trend of coefficient of
friction with increment of applied load on the pin on
disc test. Corn oil with 2 wt% ZDDP showed a desirable
kinematic viscosity value of 36.3 cSt.
