The Development of Research on Thermal Oxidation and Condition Monitoring of Ester Lubricants

Ester Lubricants are currently the most popular applied synthetic lubricants. A Large number of research on the mechanics and kinetics of thermal-oxidative degradation of ester lubricants have been carried out. These research work are very important to evaluate the thermal-oxidative degradation of the used ester lubricants and useful condition monitoring of ester lubricants. In this paper, some recent research work on thermal-oxida-tive degradation of ester lubricants and newly developed techniques of condition monitoring are reviewed.
