In the present study, Cu–4Cr–xZrC nanocomposites have been developed through powder metallurgy route by varying the proportions of zirconium carbide viz. (0–10 wt.%). The required green compacts were prepared using die set assembly in a compression testing machine. Consequently, the hot extruded samples were tested for dry sliding wear and friction using a pin-on-disc machine. SEM, XRD, pin on-disc system and Vickers hardness tester were used to evaluate the characterization, tribological properties and hardness respectively of Cu–4Cr–xZrC nanocomposites. From the observations, it was found that the friction coefficient increased progressively with increasing load and sliding distance. Furthermore, the specific wear rate (SWR) decreased for the Cu–4Cr–xZrC nanocomposites when compared to composites that of pure copper. Hardness increases with the addition of nano ZrC content into the matrix composites.
