چکیده

Abstract Developing lubricants with good electrical conductivity and tribological properties is necessary for the power equipment. Here, niobium selenide (NbSe 2 ) boron nitride (BN) were employed to act as additives fabricate lubricating greases superior properties. The grease containing different concentrations of synthesized their conductivities measured by a volume resistance meter at room temperature about 25 °C. also investigated worn surfaces characterized in detail scanning electron microscopy (SEM), x-ray photoelectron spectroscopy (XPS) Raman analyze lubrication mechanism after friction test. results showed that NbSe could effectively reduce resistivity ten times compared base grease. Tribological tests when concentration was wt%, it COF wear scar width 23.5% 12.8% under 150 N 5 Hz, indicating wt% doped exhibited outstanding In addition, based on analysis surfaces, attributed effective film generated surface, which played key role reducing anti-wear.
