Rezumat

The results of the influence of ionizing radiation on the operational properties of engine oil with metalcontaining additives are presented. It was found that irradiation of mineral-based motor oil with various doses of gamma radiation does not significantly affect its viscosity and alkali value. Irradiation with low doses contributes to a decrease in the surface tension of the motor oil due to the activation of polar active additive components and the formation of additional polar active compounds, as well as an increase in electrical conductivity due to an increase in the concentration of ion-radical complexes, which has a positive effect on the performance properties of the engine oil. The method of deter-mining the tribological characteristics of the friction machine has established that irradiation of the motor oil with a low dose of gamma radiation contributes to an increase in anti-wear and antifriction properties. The optimum dose of irradiation of a mineral-based engine oil, providing the maximum change in its performance properties, is a dose of 2 krad.
