Abstract WS₂ powder coated with copper was prepared using electroless plating technology. The WS₂-Cu matrix composites were prepared by spark plasma sintering technique (SPS) using pure Cu and Cu coated WS₂ powders as raw materials. The microstructure, mechanical properties and friction and wear properties of WS₂-Cu matrix composites prepared at different sintering temperatures were studied. The results show that WS₂ is distributed uniformly in the copper matrix and the interface between Cu and WS₂ bond well. With an increase in the sintering temperature, the hardness of composites shows an increasing trend. WS₂-Cu composites prepared at 500—750℃ have low friction coefficients (0.15—0.18). However, the composites prepared over 750℃ have high friction coefficients (0.42—0.54). The composites prepared at 700—750℃ has the lowest wear rate of (1.6—1.8)×10^-5 mm³/(N·m). The surface treatment of WS₂ powder coated with Cu improves the wear resistance of WS₂-Cu composites. The suitable SPS sintering temperature for preparing WS₂-Cu composites is 700—750℃. The plastic deformation, oxidative wear and adhesive wear were occurred during the friction and wear process in the WS₂-Cu composites. There was a significant abrasive wear on the wear surface of the WS₂-Cu composite when the WS₂ was transformed into W.
