Abstract
Abstract
Copper-based composites with different content of NbSe2 were fabricated by power metallurgy, their microstructure, microhardness and tribological properties were investigated systematically by using X-ray diffractometer (XRD), scanning electron microscopy (SEM), energy dispersive spectrometer (EDS) and wear tester. Results showed that with NbSe2 addition, except main phase Cu, minor phases such as CuxNbSe2, Cu2Se and remaining NbSe2 were formed in the composites. The microhardness of copper-based composites increased firstly, then decreased with the addition of NbSe2, but was higher than that of pure copper. Also, the wear resistance of composites was also enhanced greatly, especially for the simultaneous addition of 20%wt.NbSe2.
