摘要

Following the time-tested methods, this study focussed on the impact of AA6083 with Zirconia reinforcement to enhance mechanical properties and explore the potential of MMCs in wear applications. AA6083 was chosen purposely, given its exceptional specific strength, corrosion resistance, machinability, and good weldability. These attributes make it an ideal candidate for lightweight structures and components. Furthermore, ZrO2 was selected as a reinforcement for its unparalleled strength and toughness among advanced ceramic materials at room temperature. Its stability with Y2O3 complements the properties lacking in the AA6083 Matrix for this study. The stir-casting route was used to fabricate test coupon samples using AA6083 with varying weight percentages of micro ZrO2 (4%, 5%, 6%). The wear test was conducted on the Pin-On-Disc Tribometer under dry conditions at room temperature and under loads of 20N and 30N. The corrosion wear was also analyzed using the Potentio-dynamic polarization test, which confirmed the high corrosion resistance of the 4% Zr sample. Various intermetallic phases, such as Al–Ti–Zr and Al–Mg–Zr, were observed during the XRD characterization. Furthermore, 4% of the sample displayed high Crystallinity, indicating a well-densified sample with sound mixing, compaction and refinement in composite materials. SEM and EDAX are conducted to analyze its morphology. The ultimate tensile strength (UTS) of 121.42 MPa was observed, and a more excellent range of strain hardening for 4% of the sample compared to the other two samples. This work provides a profound scope for future work, likely in bulk microstructured alloys with low-soluble components.
