Abstract: The current research looks into the aluminum-based metal matrix nanocomposites tribological behavior fabricated using the Stir Casting Method.Multi-walled Carbon Nanotubes (MWCNT's) are used as reinforcements to improve the quality of metal properties and reduction in wear rate.In the current work, the metal matrix Aluminum alloy (LM29) was chosen to be reinforced with MWCNTs (with 0.25 wt%, 0.50 wt%, and 1.00%) to produce Metal Matrix Nanocomposites.A computerized pin-on-disc setup was used to conduct the entire tribological experiment, with input variables including the MWCNT composition (0.25%, 0.50%, 1.0%), cooling method and stirring speed (250, 450, and 650rpm), all while maintaining a constant load of 20 N. The observations are created using Taguchi (L9) orthogonal array, which is one of the most reliable methods.In comparison to compositions, ANOVA revealed that sliding distance is the most adaptable factor.All of the tests were conducted with a constant load of 20 N, and ANOVA showed that the kind of cooling is the most important element.Finally, worn-out regions of the specimens were examined using scanning electron microscopy (SEM), and the value of the regression equations was assessed using a confirmation test.For all the combinations considered, the confidence interval 95% with a error of 5% was achieved.
