Mechanical properties of Cu-TiB/sub 2/ nanocomposite by MA/SPS

Cu-TiB/sub 2/ was fabricated by combination of mechanical treatment, SHS (self propagating high temperature synthesis) and SPS (spark plasma sintering). The feasibility of Cu-TiB/sub 2/ composites for welding electrodes and sliding contact material is investigated through the experiments on the mechanical properties, wear resistance and electric conductivity. Various tests are performed for the Cu-TiB/sub 2/ nanocomposites with the content of TiB/sub 2/ from 2.5 to 10 wt% pure copper specimens are also tested for comparison.
