The Effect of Volume Fraction of β-SiC on the Microstructures and Bending Strengths of β-SiC/Cu Composites

Abstract:

In order to improve the interfacial wettability between Cu and β-SiC, electroless plating was employed to deposit a copper film on β-SiC particles. The β-SiC/Cu composites with different volume fraction ( from 30% to 60% ) were fabricated by hot-press sintering technique. The microstructures, bending strengths were investigated by SEM and a tensile machine. The results showed that the uniform and continuous Cu coating on the β-SiC particles can be obtained after electroless plating. With the increase of volume fraction of β-SiC particles, the bending strength decreased gradually. The fractographs revealed that the composites had mixed-fracture characteristics of cleavages and dimples.
