SPECTROMETRIC METALS ANALYSIS OF OILS - ARMY GENERAL PURPOSE VEHICLES.
Abstract
Wear metals in engine and gear oils were determined spectrometrically at intervals during a 20,000-mile road test of twenty general purpose Army tactical vehicles. Lubricants from several different suppliers were used and supplementary data regarding the physical and chemical properties of the used oils were obtained to permit an evaluation of spectrometric metals analysis as a diagnostic aid to engine and gear maintenance. The results indicate that connecting rod bearing failure due to rapid wear may be predictable. However, correlation of normal wear with metals concentration data could not be established. Engine oil contaminants containing boron, silicon, and sodium were readily detected. Oil additive deterioration and oil sludging were shown, in some cases, to be indicated by barium, calcium, phosphorus, and/or zinc depletions. Wear metals in gear oils were found to be high without significant failures. (Author)
