Abstract
Particle-reinforced aluminum metal matrix nanocomposites (MMNCs) garnered huge attention in recent years, owing to their increased wear properties and mechanical characteristics. Metal matrix composites and alloys often make use of nanoparticles of alumina and titanium carbide for reinforcing purposes. Fewer details are known about hybridized MMNCs that have been fortified with different types of nanoparticles. The characteristics of hybrid nanocomposites are evaluated in comparison to those of nanocomposites reinforced with individual reinforcements. A 100 gmf stress was applied for 10 seconds to test the specimens' Vickers micro-hardness. The hardness increased by 114% and the compressive strength by 60% with the addition of nanoparticles to the metal matrix. Tests were conducted on the specimens' dry wear characteristics at speeds of 550, 600 and 650 rpm with loads of 40, 45 and 50 N. A higher carbon reinforcing level in the metal matrix results in a higher wear resistance.
