Abstract:

Since the reliability of wear metal determinations depends on the integrity of the primary standards used to calibrate the instruments, standards were synthesized and evaluated for use in the Oil Analysis Program OAP. The standards currently used by the Air Force, in addition to Cannon, metal caprates, metal beta-diketonates, and NBS standards were evaluated for their long term stability. Two state-of-the-art plasma emission instruments were evaluated for their potential applications to the AF OAP. The goal of this effort was to improve the particle detection capability of oil analysis instruments. The sample introduction systems used by these instruments could not efficiently transport particles to the plasma sources. However, the dc plasma instrument could analyze particles better than currently used instruments. Research was also conducted to identify and characterize wear debris found in typical used turbine engine lubricating oils. Methods were developed to determine the concentration of organometallic, metallic and metal oxide species in oils for Mg, Cu and Fe. An investigation was conducted to determine and recommend optimized atomic absorption procedures for analysis of wear metals in aircraft lubricating oils. Optimization procedures and recommended AA methods are included. A method was developed to determine the actual concentration of wear metals in authentic used aircraft engine oils. It is quantitative for Al, Cr, Cu, Fe, Mg, Mo, Ni, Pb, Sn and Ti metallic particles.
