Description
Summary:This study investigates the wear behaviour of aluminium, vanadium pentoxide and boron carbide, metal matrix composites. Specimens were prepared for various weight fractions of V 2 O 5 particles added with aluminium and 2% B 4 C powder compaction using a suitable die assembly on a 1.0 MN capacity hydraulic press and sintering at 500°C. The use of powder metallurgy to create Al matrix composites reinforced with V 2 O 5 particles has yet to be attempted. The ongoing study, which examined the wear behaviour of composites made up of Al– x V 2 O 5 –2B 4 C using the mechanical alloying method, discusses the function of reinforcement on the wear mechanism of metal matrix composite. The composites were analysed, X-ray diffraction was used for material characterization, scanning electron microscope analysis for worn surface characterization, and energy dispersive spectrum was used to determine the situation of the mechanically mixed layer and tested the friction coefficient and wear loss of the composites on a pin-on-disc tribometer. Addition of V 2 O 5 with 2% B 4 C results in a good change in its specific wear rate, reduced coefficient of friction, and better formation of the mechanically mixed layer.
