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.

To develop our understanding of the effect of the tribological properties on the oil oxidation and the effect of oil oxidation on the tribological properties, we have investigated the tribological performance of the used gear oil when it is used to lubricate in heavy duty truck using a steel-on-steel sliding interaction
In the present paper we have investigated three parameters as the viscosity, microstructure and tribology of used gear oil
Summary
Lubricant oils are important in many industries and essential and expensive components of machine systems es-How to cite this paper: Zeng, Q.F., Dong, G.N., Yang, Y.L. and Wu, T.H. (2016) Performance Deterioration Analysis of the Used Gear Oil. (2016) Performance Deterioration Analysis of the Used Gear Oil. Advances in Chemical Engineering and Science, 6, 67-75. The reasonable replace of lubricant oil with efficient and economic method is considered urgent. Many researchers focused their attention to investigate the performance of the used oils with the conventional technologies and analyze the deterioration process and the failure mechanism of lubricant oils [2] [3]. In order to avoid an engine and axle failure, the lubricant oil must be replaced before it loses its protective properties. A basic advantage of this method is the possibility of obtaining spectra immediately from the gear box of the axle package The purpose of this method of early failure detection in oil lubricated machinery is to discover the degradation of lubricant oil. The trends include energy-efficient oils and longer-life oils to extend drain and maintenance intervals
