Abstract:
their exceptional strength-to-mass ratio and resistance to high temperatures. This study investigates the devel
opment and wear resistivity performance of Aluminium Matrix Composites (AMCs) reinforced with SiC and TiB2
particles. The experimental work involved fabricating AMCs using Aluminium Alloy 7075 as the matrix material
with varying weight percentages of SiC and TiB2 reinforcements. Tribological tests were conducted under
different conditions of applied load, sliding speed, and sliding distance to analyze the wear behavior of the
composites. Results revealed that higher weight percentages of reinforcement led to lower wear rates, particu
larly at elevated sliding speeds. X-ray diffraction analysis confirmed the presence of SiC and TiB2 particles in the
composites. It is observed that greater applied loads caused greater wear rates, bigger grooves, and substantial
frictional heat production, demonstrating a direct relationship between load weight and wear performance. The
study indicated that sticky wear management lowered wear rates at longer sliding distances not abrasive wear at
shorter distances. The significance of this study lies in its contribution to optimizing the composition of multi-
phase reinforced AMCs for enhanced wear resistance in various industrial applications.
