Abstract: This study aimed to enhance the wear resistance of the AA8090 material. Nanoparticle-reinforced AA8090 metal matrix composites were manufactured using the conventional stir casting process. Totally, three types of composites were fabricated by varying the cerium oxide (CeO 2 ) nanoparticle content. The different materials prepared were AA8090, AA8090/1.5 wt% CeO 2 , AA8090/3 wt% CeO 2 , and AA8090/4.5 wt% CeO 2 . Properties like microhardness, tensile strength, wear rate, and coefficient of friction of the developed composites were determined. The results showed that the inclusion of CeO 2 nanoparticles improved the different properties of the AA8090 material. An optimum level of 3 wt% CeO 2 in AA8090 showed better performance. Furthermore, the AA8090/3 wt% CeO 2 composite exhibited a maximum hardness and tensile strength of 158 HV and 546 MPa, respectively, which was 18 and 20% higher than those of AA8090. Furthermore, the same composite displayed a slightest wear rate (0.045 × 10 −3 mm 3 /m) and coefficient of friction (0.2). Hence, it is concluded from this research that the AA8090/3 wt% CeO 2 could be a suitable material for aero, military, and marine applications as it showed a good performance.
