Implication

Randomized trial evaluates mechanical and tribological properties of Al6061/SiC composites, revealing optimal SiC content for performance enhancement.

Key Points

This study aims to investigate the effects of silicon carbide weight fractions on the mechanical and tribological properties of Al6061/SiC composites.
Five composite formulations with SiC weight fractions of 0, 4, 8, 12, and 16 percent fabricated by stir casting at 700°C.
Characterization for density, Vickers hardness, tensile strength, elongation, and Young's modulus following standard ASTM procedures.
Tribological testing using a pin-on-disc tribometer and Taguchi L18 design varying SiC content, load, and sliding speed.
12 wt% SiC yields UTS of 218 MPa (+47.3% over Al6061), hardness of 89.4 HV (+53.1%), and minimum wear rate.
ANOVA indicates SiC content significantly influences wear rate (44.8%), followed by applied load (29.6%) and sliding speed (17.4%).
Wear mechanism shifts from severe adhesive wear in Al6061 to mild oxidative-abrasive wear in 12 wt% SiC composite.
