In the present study, hardness and tribological properties of nanostructured copper reinforced with SiC nanoparticles
of various volume fractions (0, 2, 4, and 6 vol%) were investigated. The nanocomposites were fabricated
by high-energy mechanical milling and hot pressing method. The Cu-SiC nanocomposites showed enhanced
hardness and wear resistance against WC counterface. The hardness and wear resistance of the
nanocomposite increased with increasing the amount of SiC nanoparticles up to 2 vol% in the matrix, but they
decreased at higher percentages of SiC (4 and 6 vol%). Flake formation-spalling and abrasion were identified as
the predominant wear mechanisms. It was found that reducing the normal load and increasing the amount of SiC
resulted in an increase in the friction coefficient of the nanocomposite.
