Characterization of debris from F404 enging oil filters by energy dispersive X-ray fluorescence

摘要

The Department of Defense (DoD) Oil Analysis Program uses rotrode Atomic Emission Spectroscopy (AES) to analyze for elements in lubricants. The determination of the concentrations of elements by AES is limited to particle sizes of approximately 10 microns or less. The current trend in the DoD is to place 3 micron absolute filters in lubricant systems that remove the majority of the particles that AES uses to determine the condition of the equipment rendering AES an unsatisfactory method to monitor these fine-filtered assets.
