Tribological Behavior of Powder Metallurgy Processed Carbon Nanotube Reinforced Alsi Functionally Graded Materials

Abstract

Tribological behavior of powder metallurgically processes AlSi-MWCNT functionally graded materials was apparatus with pins on discs was examined. Using a Taguchi design of experiments, the signal-to-noise ratio, the analysis of variance, and an orthogonal array were all used to determine the best testing parameters. Analysis revealed wear loss occurs due to increase in load and sliding distance and reduced with MWCNT increased content in FGM. The composites with 1wt% of FGM exhibited both excellent wear resistance and friction coefficients. Wear mechanisms help in understanding the morphology of worn surfaces. The wear mechanism is dictated by delamination layer and other oxide layers. Overall, the findings showed that AlSi-MWCNT functionally graded materials are regarded as remarkable materials in industries where wear-resistant components are crucial, such as aerospace and automotive engineering
