In this study, hybrid composite materials were produced by adding SiC (Silicon carbide) and MWCNT (Multi-walled carbon nanotube) to Zinc-Aluminium (ZA40) alloy, sintering under 700 MPa pressure and 500 °C using mechanical alloying and hot press technique. Hybrid samples were produced with 2% MWCNT constant and SiC ratio 1-2-3 and 4% by weight in the mixtures. The mechanical properties such as hardness and porosity of the produced hybrid composite materials were determined and their wear properties were investigated by traveling 300 m using 10 and 20N loads under 300 rpm constant speed in a ball-on-disc wear test setup. The obtained microstructure and wear surface images showed that the SiC and MWCNT reinforcement contributed significantly to the wear resistance of the hybrid composites, and in the SEM analyzes of the worn surfaces, there was a transition from abrasive wear to adhesive wear in the wear mechanism.
