Abstract

The composition and morphology of Cu-coated SiC

powder prepared by electro-plating have been investigated.Moreover

Cu-35%SiC

heat sink materials were fabricated by hot pressing based on the coated powder

and its microstructure and thermo-physical properties have been observed.The results show that SiC

particle is uniformly distributed in the matrix with ideal interfacial bonding.With a given condition

the thermal conductivity of the Cu-35%SiCp heat sink materials is 165.7 W/（m·K）and the thermal expansion coefficient is 15.1×10-6/K in the range of 30～200 ℃

which provides a reference for further research.
