Preparation and Tribological Behavior of Cu-based Electrical Contact Composite Containing NbSe2 in Vacuum

doi:10.15541/jim20130571

Abstract

Abstract:

Cu-graphite self-lubrication composite containing nano NbSe₂ (0-9wt%) was fabricated by powder metallurgy technology. Friction property of the sample was investigated using micro-tribometer and ultra-low-temperature tribometer under atmosphere and vacuum conditions. The microstructure, phase and wear scar were also investigated by XRD and SEM. The results showed that tribological property was significantly improved after nano NbSe₂ being added to the Cu-graphite self-lubrication composite. The composite with nano NbSe₂ (5.5wt%) had smaller friction coefficient (μ=0.185) under vacuum dry friction conditions and higher carrying capacity than those of the composite without NbSe₂. It was found that the wear could be attributed to adhesive wear together with contact fatigue wear.

Key words: self-lubrication, NbSe2, friction and wear, nano material, Cu-graphite
