Abstract
This study compares the influence of processing route and SiC content on the microstructure, mechanical properties and tribological behavior of Al–4Cu–xSiC (x = 0, 5, 10 wt%) composites. Materials were fabricated by powder metallurgy using two routes: conventional pressing and sintering (PM) and hot extrusion before sintering (HE). Hot extrusion improved particle distribution, grain refinement and oxide film disruption. Relative density decreased from 98.74 % (unreinforced) to 96.29 % (10 wt% SiC) in PM composites, while HE samples showed ∼91.9 % but more uniform density. Hardness rose from 55 to 60 HB with SiC in PM, while extruded materials remained near 56 HB. Tribological tests (dry sliding, 50 N, 500 m) revealed that extrusion enhanced wear resistance and friction stability. The best result was for 5 wt% SiC HE composite, with lowest friction (≈0.27) and minimal loss of mass (0.00123 g). SEM confirmed adhesive and abrasive wear mechanisms.
