Effects of Multi Walled Carbon Nanotube and Silicon Carbide Reinforcement on Wear Performance in Zinc-Aluminium Alloys

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 500 °C using mechanical alloying hot press technique. Hybrid samples with 2% constant ratio 1-2-3 4% weight in the mixtures. The properties such as hardness porosity of determined their wear investigated traveling 300 m 10 20N loads rpm speed a ball-on-disc test setup. obtained internal structure surface images showed that reinforcement contributed significantly resistance composites, SEM analyzes worn surfaces, there was transition from abrasive adhesive mechanism.
