【 摘 要 】

Aluminium alloy hybrid composites are in high demand for advanced scientific applications due to their high strength, low weight, and enhanced tribological properties. A hybrid composite of aluminium alloy (Al7075) and aluminium oxide (Al2O3) and E-glass shot fibres was produced using a sand moulding technique in an electric resistance furnace. The objective of this research was to look at the wear characteristics of Al7075-Al2O3-E-glass hybrid composites with various Al2O3 (3-12%) and E-glass weight percentages (2-6 percent). The sliding distance (500, 1000, and 1500 m), load (10, 20, and 30N), Al2O3 (3, 6, and 9 %), and E-glass (2-6 %) are the wear characteristics that are considered. Wear testing is carried out using pin-on-disc equipment (WTE 165 model, Version-EV00) in line with the Taguchi L9 orthogonal array. Taguchi analysis was done on the collected data to find SN plots. Regression analysis was done along with ANOVA to find relationships between different factors selected. In order to reduce the wear rate of hybrid composites, the optimal wear parameters are determined. As the percentage of reinforcements increased, the rate of deterioration decreased. SEM scans revealed the attachment and displacement of unintended wear debris, as well as the uniform distribution of Al2O3/E-glass particles.
