Abstract
The present work is triggered on the processing and characterization of magnesium AZ9E/LHA composites. Lanthanum hexa-aluminate (LHA) nanoparticles are prepared by chemical precipitation and filtration technique followed by characterization studies conducted through X-ray peak profile analysis and field emission scanning electron microscopy supported by energy-dispersive spectroscopy (EDS). Later on lanthanum hexaluminate powders (LHA) were presented as a candidate process to disseminate in the AZ91E alloy. The stir casting procedure was used to manufacture magnesium AZ91E/LHA composites. The effects of varying the reinforcement weight fraction on particle distribution, particle–matrix interfacial interactions, physical, tribological and mechanical properties were investigated. The existence of components and a uniform distribution of particles in the composite were revealed by SEM and EDS examination. The mechanical characteristics of both reinforced and unreinforced composites were assessed and reported. An increment of 18.61% micro-hardness and 17.43% in tensile strength is observed. The worn surfaces of all fabricated composites were examined using scanning electron microscopy for understanding the wear mechanism.
