Окисна стабільність змащувальних матеріалів з фулереновими наноприсадками

Abstract

Purpose: The purpose of this article is to investigate the possibility of using fullerene additives to fuels and lubricating materials for the improvement their oxidative stability and to determine the concentration of nanoadditives in hydrocarbon solutions. Research methods: Methods of increasing the oxidative stability of Castrol Magnet SAE 5w-30 oil by adding fullerene C60 and determination the content of nanoadditives in the hydrocarbon liquids were considered in the article. Results: The optimal concentrations of fullerene additives are determined, the method of photoelectrocolorimetric determination of their concentrations in lubricants is developed, the experimental data of optical properties of C₆₀ solutions are obtained and the amount of fullerene in solution is calculated. Discussion: It is proposed to use fullerenes as an antioxidant additive, which significantly improves the thermal oxidative stability of oils and the method of determining of fullerene content.
