Microstructure and Mechanical Properties of SiC/Al Nanocomposite

Abstract

In this paper, nanozised SiC particle has been chemically treated with acetone and hydrofluoric (HF) and then electroless plating with CuSiO4and HCHO solution subsequently. The results show that the nanosized SiC particle can be deposited with Cu coatings and made them more likely distributed in aluminum powder homogenously. Bulk SiC/Al nanocomposite prepared by hot pressing and the mechanical property of the composite were studied. The clothed SiC particle has an easier distribution in aluminum matrix than ordinary SiC particle and the corresponding composite has a higher strength and hardness.
