Fabrication and Mechanical Properties of SiC/Cu Composites with Zn Addition by Hot Pressing Sintering
SiC/Cu composites exhibit low density,low coefficient of thermal expansion and excellent mechanical properties.In this study,Zn of 2 wt.% was added as the sintering activator,and the high volume faction (60%) SiC/Cu composites was fabricated by hot pressing sintering technology.The phase composition and morphology of as-prepare samples were characterized by X-ray diffraction (XRD) system and scanning electron microscopy (SEM) equipped with an energy-dispersive spectroscopy (EDS) system.The as-prepared SiC/Cu composites were dense and uniform as well as void free.The results show that SiC/Cu composites can reach excellent mechanical properties of SiC/Cu composites.With the increase of sintering temperature,Vickers hardness and the bending strength of the samples increased obviously and the as-prepared SiC/Cu composites achieved a maximum Vickers hardness and bending strength respectively of 195MPa and 140MPa.
