Determination of Iron Contamination of Used Lubricating Oil for Use in Measuring Rates of Wear in Aircraft Engines

Abstract

An investigation was made to develop a means of determining iron contamination of used lubricating oil in aircraft engines in order to study wear rates of piston rings and cylinder walls. One method for the separation of the iron from the used oil was by burning and dissolving the residual ash containing the iron in an acid. Another method used was by extraction of the iron from the oil and acid. The amount of iron in the resulting solutions was determined by using o-phenanthroline to form a colored complex with the iron. Results of tests utilizing both methods are given.
