The mechanical characteristics of composite materials play a crucial role in
advancing technology. The present investigation employed the stir-casting method to
produce hybrid aluminum matrix composites. Silicon carbide and aluminum oxide
were selected as reinforcements in order to improve mechanical performance.
Aluminum matrix composites (AMCs) were synthesized through the implementation
of the stir-casting technique, incorporating varying volume percentages of aluminum
oxide (10%, 15%, and 20%) with a consistent volume fraction of silicon carbide
(15%) ang 10% graphite(G). The constructed AMCs were subjected to testing in
order to evaluate their tensile strength (UTS), hardness (VHN), and wear rate
(WR%). The wear rate was quantified across weights (10 N, 15 N, 20 N, and 25 N)
and sliding velocities (0.3 m/s, 0.6 m/s, 0.9 m/s, and 1.3 m/s). In this study, a
comparison was made between the mechanical characteristics of the manufactured
aluminium matrix composites (AMCs) and those of the Al6063 alloy. The work
outcomes indicated that the incorporation of silicon carbide and aluminium oxide
resulted in a critical reinforcement of both the tensile strength and hardness
properties. The tensile strength exhibited a notable rise, rising from an initial value
of 590 MPa to a final value of 900 MPa. Similarly, the hardness of the material
experienced an upward trend, ascending from an initial measurement of 70VHN to a
final measurement of 90VHN. The wear rate exhibited a positive correlation with the
magnitude of the applied load. Nevertheless, the variation in sliding velocity yielded
distinct consequences. The velocity exhibited a quick increase until it attained a peak
value of 0.9 m/s, then undergoing a sharp decline |
