Abstract

A new conductive grease was synthesized using a nanometer powder, i.e., Sb doped SnO2 (ATO), as an additive. The typical properties of this new conductive grease were investigated in detail. The results indicate that ATO can dramatically improve the dropping point and reduce contact resistance. The tribological properties of the new conductive grease were investigated using the MFT-R4000 reciprocating friction and wear tester. The tribol-test results indicate that ATO can dramatically improve the tribological properties of the grease. When the ATO concentration is 0.1wt%, the grease demonstrates the best friction reduction properties; when the concentration is 0.5wt%, the grease demonstrates the best anti-wear properties. The worn surfaces were observed and analyzed by scanning electron microscopy and energy-dispersive X-ray spectroscopy, and the friction mechanisms for the new conductive grease are proposed. The excellent tribological properties of the new conductive grease are attributed to the mechanical effect of ATO, and the film formed by Sn and Sb elements or metallic oxide deposited on worn surfaces during the friction process.

Keywords
