After adding 2% (vol.) graphite to the aluminum matrix, 4 different amounts (3%, 6%, 9%, and 12%) of ZrO2 were added. The mechanically alloyed composite powders for 60 minutes were cold-pressed under 700 MPa pressure and green parts were produced. The green parts produced were sintered at 600 °C under argon for 120 minutes. The sintered ZrO2 reinforced aluminum composite materials (AMCs) are characterized by the scanning electron microscope, X-ray diffraction, and hardness and density measurements. Wear tests were performed on a standard pin-on-disc wear testing device with three different loads (10-20-30 N) at a sliding speed of 0.6 ms-1 and four different sliding distances (53, 72 and 94 m) according to ASTM G77 standard. As a result of the studies, the microhardness and density increases as the amount of ZrO2 in the composite material increases. As a result of the wear tests, the highest weight loss was obtained in the non-reinforced Al-2Gr matrix alloy, while the lowest weight loss was obtained in 12% ZrO2 reinforced composite materials. However, it was observed that there was a decrease in the friction coefficient with increasing amount of reinforcement. © 2019, TUBITAK.
