Popis: This article investigates the chemical stability of IPM-10, MS-8RK, and AMR-10 oils that had been in service for various lengths of time in aircraft lubricating systems and components. Infrared spectroscopy reveals that the intensity of absorption of certain additives, and the contents of these additives in the oils, do not change during the service of the oil. A comparison is made of the changes in content of an antioxidant additive in MS-8RK and IPM-10 oils and the thermal-oxidative stability of these oils. The level of thermal-oxidative stability of the oil samples is not significantly different from that of the fresh oils, which indicates that the oil samples with the given content of antioxidant have a reserve with respect to additive content and with respect to chemical stability. The possibilities for investigation of oil stability after various terms of service in aircraft equipment systems and components by means of IR spectroscopy is demonstrated. Includes 2 tables.
