Study on dry sliding wear characteristics by taguchi analysis of al-mg-si-cu-sic composite prepared by powder metallurgy method

Abstract

There is a growing attention among researchers to the production of new composites with low-density and low-cost processes. Aluminum based metal-matrix composites (AMMC) offer solutions for new product development. In this paper, a newly developed Al-Mg-Si-Cu-SiC composite was manufactured by powder-metallurgy, and the wear mechanism of aluminum composite materials was carried out using the pin-on-disk method. The purpose of the experimental plan was to correlate the factors that influenced the wear operations in order to execute them with a minimal rate of wear and coefficient of friction (COF). The experiment was based on the Taguchi design with OA (orthogonal arrays) to correspond to the effects of load applied, sliding speed, and distance. The design features are distinctive and integral attributes of the method, affecting and determining the wear characteristics of composites.The predictive models developed for various machining performance characteristics employing response surface methodology are effective in terms of adequate, statistically significant, and probabilistically validate because of their higher R2-values, P-values less than 0.05 and larger AD-test p-values. The data generated for the Al-Mg-Si-Cu-SiC AMMC will be useful for the industry.
