Study of Wear Properties of Recycled Composite Zn-Al Alloy Reinforced with Hybrid Nanoparticles

Abstract

In this research, the stir casting technique used to produce ZA-12 alloy hybrid composites reinforced by nanoparticles (SiC and BN) with different weight percentages. Pin on disk used for the wear test for ZA-12 alloy and its composites. It is found that the nanoparticles improved the hardness and the wear properties of alloys. Since nanoparticles impede dislocations movement, causing an enhancement in the mechanical properties. The microstructure and the phases formed were analyzed using an optical microscope with various magnifications. SEM analysis denotes the uniform distribution of the different weight percentages of SiC and BN nanoparticles in the based alloy, which explains the improvement in the wear properties.
