Abstract
Using a simple one-step hydrothermal method, benzyl triethylammonium chloride was used to assist the synthesis of double core-shell oxygen-incorporated molybdenum disulfide (DB-O-MoS2), and its friction and wear properties were measured on the MRS-10A four-ball testing machine. They were characterised by X-ray diffraction, scanning electron microscope, transmission electron microscope, thermogravimetry, Brunner−Emmet−Teller and Fourier transform infrared spectroscope. Friction and wear properties of DB-O-MoS2 were measured at different concentrations. The results showed that the tribological properties of SN 5W-40 base oil have been improved by adding the DB-O-MoS2 as lubricant additives. The possibility of DB-O-MoS2 mechanisms by which the nanolubricants improved the tribological properties were put forward. Therefore, research on DB-O-MoS2 is beneficial to the development of new engine lubricant additives.
