Mechanical properties, tribology and electrochemical studies of Al/Fly ash/eggshell aluminium matrix composite
Abstract
<p>This work was carried out to investigate the effect of carbonized eggshells (CES) and fly ash on the microstructure, mechanical properties, wear, and corrosion characteristics of Al-Si12. The weight fraction (wt.%) of the CES particles was kept constant at 2.5 wt.%, while that of fly ash was varied at 2.5 wt.%, 5.0 wt.%, 7.5 wt.%, and 10.0 wt.%. The selected fabrication route was stir casting. The x-ray diffraction (XRD) analysis of the cast aluminum matrix composites (AMCs) revealed the presence of phases including α-aluminum, SiO<sub>2</sub>, and Si with the formation of the intermetallic CuAl<sub>2</sub> phase. The microhardness of the cast samples increased with increasing weight fraction of the reinforcements up to the 7.5 wt.% fly ash sample. The tensile strength and compressive strength were highest for the 2.5 wt.%/CES 2.5 wt.%. Tribology studies showed that the lowest wear rate of 4.91 × 10<sup>-5</sup> mm<sup>3</sup>/Nmm was obtained for the 2.5 wt.% fly ash sample, while the corrosion studies showed that the corrosion rate of 2.70 × 10<sup>-5</sup> g/hr was lowest for the 2.5 wt.% fly ash as well.</p>
