Abstract:
The main aim of this study is to fabricate SiC particulate reinforced aluminum functionally graded (Al FGM) brake disc
and to find the optimal friction and wear parameters using grey relational analysis. The A356-20%SiCp melt was processed
using liquid metal stir casting technique followed by centrifugal casting resulting in the formation of a functionally
graded Al FGM brake disc. Due to the centrifugal force, the hard SiC particles were moved towards the outer peripheral
area of the brake disc, which enhances the wear resistance. The microstructural analysis is done on brake disc to show
the segregation of SiC particle from outer periphery to inner region. The pins for conducting wear study are machined
from particle-rich zone, particle intermediate zone and particle depletion zone at a distance of 15 mm, 45 mm, 75mm
respectively from the outer periphery of the brake disc. The analysis of variance is also done to investigate the major
factors that significantly influence the wear behavior in Al FGM brake disc. The observed results show that the particlerich
zone is the major effect on the dry sliding wear followed by applied load
