Abstract: Aluminium composites' mechanical and tribological performances with silicon carbide (SiC) have been studied. Aluminium (AA6061) alloy composites were fabricated using the liquid metallurgy method by varying silicon carbide reinforcement from 5% to 20% by weight. The scanning electron (SE) microscope method helps to analyse the dispersion of SiC in aluminium materials. The samples with 15% wt varying reinforcement SiC have improved tensile strength, improved hardness behaviour and impact strength. However, the design of experiments (DOE) was employed to achieve the optimum conditions in the wear parameters like weight (wt in %) SiC sliding velocity (m/s), applied load (N), and sliding distance (m). Analysis of variance (ANOVA) a statistical method, has been employed to recognise the essential and interaction parameters that influence the composite's wear behaviour and friction coefficients. On the other hand, the tribological (wear) properties like rate of wear and friction coefficient have been lowered by the addition of SiC reinforcement.
