Effect of Nano BN Addition on the Properties of an Aluminum Metal Matrix Composite

In the present work, the wear rate and hardness of recycled Aluminum alloy based metal matrix composite that reinforced with nano Boron Nitride with (2%, 4%, 6%, and 8%) weight percentage with 33 nm particle size were evaluated. A stir casting process was applied to fabricate composite the mechanical and metallurgical characteristics of the fabricated composite were evaluated through the hardness and wear test. The results indicate that the value of hardness increased and wear rate decreased with increasing the BN percentage due to high surface area to weight ratio for nanoparticles.
