A Study On The Characterisation And Preparation Of Aluminium Composite

Abstract

In this publication, we present the results of a Brinell hardness test and a dry sliding wear behaviour study on AA 5083 aluminium that was strengthened with SiC particles using the stir casting technique. SiC particles with different volume fractions (3, 5, and 7 wt%) were utilised in the synthesis. Using a pin-on-disc testing machine, we analysed the wear behaviour of the aluminium alloy and its
composites. Dry sliding wear of metal matrix composites has been investigated in terms of factors such as applied load, sliding speed, sliding distance, and reinforcing percentage (MMCs). A plan of experiments, based on the techniques of Taguchi, was done to obtain data in controlled fashion. An orthogonal array of L9 (34 ) and signal to noise ratios as smaller the better was selected. Analysis of
variance (ANOVA) was employed to investigate the influence of wear parameter on pin of aluminium MMCs. Multiple generalised regressions model was used to determine the correlation. The experimental findings predicted by the aforementioned correlation were then compared to the results of the conformation tests.
