ABSTRACT: In the present paper, we
have investigated the tribological properties and microstructure of the used
gear oil theoretically and experimentally. The deterioration process of the
in-service gear lubricant oils was also discussed. The viscosity and
microstructure of oils running different mileages were analyzed by viscometer
and Fourier Transform Infrared Spectroscopy (FTIR), respectively. In addition,
the friction and wear behaviors of the friction pair of the GCr15 steel ball
and disc were investigated using a ball on disc tribometer under different
mileages’ gear oils lubrication conditions. These techniques give reproducible
and reliable data with which to evaluate the severity of deterioration process
of oils. The objective of this work is to understand the deterioration process
of gear oil and analyze the influence of deterioration on the performance and
microstructure of lubricant oils used in gear box. Possible explanations of
deterioration process as well as its influence on friction and wear behaviors
are also discussed. The results reveals the tribological properties of used
oils depended on strongly the microstructure and its deterioration process of
oil.
