| 内容記述 | Autoxidation is a chain reaction that occurs in oil when it is in the presence of free radicals (oxidants) that can be stopped by adding another substance to trap the radicals. To accomplish this, radical scavengers called antioxidants are commonly added to lubricating oils. Zinc dialkyl dithiophosphate (ZnDTP), which provides both good antioxidation performance and wear resistance, has been used for that purpose in the past, but because it contains phosphorus, zinc and sulfur, which cause catalyst poisoning, alternative additives are currently being sought. Fullerenes, which have recently attracted significant interest due to their ability to reduce friction and wear, are now being explored due to their oil antioxidant capabilities. Furthermore, some studies have indicated that static electricity spark discharges resulting from electrification flows could promote oil oxidation. In the present study, we conducted experiments on oil containing 0.1 wt% fullerenes by attempting to promote oxidation of the oil using an inhouse fabricated electrostatic discharge generator. These samples were then heated at 80 °C and maintained at that temperature for four weeks during which they were analyzed by FT-IR once each week. Since our obtained results found that no oxidation occurred in the oil to which fullerenes had been added, we conclude that fullerenes effectively suppress oil autoxidation by trapping both alkyl and peroxy radicals, while conventional antioxidants target only peroxy radicals. | |||||
