Abstract
The article presents the results of a study of the effect of various pollutants and thermo-oxidative aging on the dielectric constant and tribological properties of TP-22c turbine oil. It has been experimentally established that the introduction of contaminants such as 40X steel powder, quartz sand and water into the oil, as well as its aging process, lead to a statistically significant increase in dielectric constant and deterioration of antifriction characteristics – an increase in the friction coefficient and the diameter of the wear spot. A strong positive correlation was found between an increase in permittivity and an increase in the friction coefficient, which confirms the possibility of using permittivity measurement as an indirect method for rapid diagnosis of oil condition and predicting wear of friction units without complex tribological tests.
