Electrical Conductivities and Tribological Properties of Lithium Salts Conductive Grease

doi:10.3901/JME.2015.15.061

Abstract

Abstract: Three kinds of conductive grease are prepared by adding three lithium salts, including lithium tetrafluoroborate (LiBF4), lithium hexafluorophosphate (LiPF6) and lithium bis (trifluoromethane sulfonamide) (LiNTf2) in lithium grease. The electrical conductive properties of the prepared conductive greases are evaluated by using a DDSJ-308A conductivity meter, a GEST-121 volume surface resistance tester and a HLY-200A circuit resistance tester, respectively. And the tribological behaviors of three kinds of lithium salts are investigated by an Optimol SRV-I oscillating reciprocating friction and wear tester at room temperature (RT). The results demonstrate that the addition of lithium salts can enhance the lithium grease conductivity and also dramatically improve the tribological properties of lithium grease, the wear volumes are valued by Micro-XAM3D noncontact surface mapping profiler, wear surface are characterized and analyzed based on scanning electron microscope (SEM) and PHI-5702 multifunctional X-ray photoelectron spectrometer (XPS). The results indicate the improvement of tribological properties should attribute to the formation of boundary ﬁlm consisting of both absorption ﬁlm and chemical reaction ﬁlm.
