Friction and wear of bearing material under water contaminated compressor oil
M.N. Syahirah, A.N. Farhanah, M.Z. Bahak
Abstract
Water has been defined as a destructive contaminant which may cause a detrimental impact on bearing performance. Nevertheless, many previous studies only made the research after the lubrication failure occurred, but they also only focused on the contaminated lubricant, but not on the new lubricant which may be taken as a preventive measure before bearing life will be reduce. Thus, experiment was conducted to identify the effect of water contamination to the lubrication performance of the compressor oil. Four ball tester was used by following standard test methods ASTM 4172 to determine the friction and wear characteristics of water contaminated lubricant. Water contamination was varied from 0% to 50% by volume percentage. The result indicates that water contamination give more effect on wear scar diameter and only has small effect on friction coefficient.
