“…% of Al2O3 reinforced Al composite was carried out at solution temperatures of 510°C, 530°C and 550°C and thermal aging at 140°C, 160°C, 180°C, 200°C and 220°C for studying the influence of heat treatment on hardness & electrical conductivity. As per the study, we observed the highest improvement of 25.92% and 9.57% respectively in hardness and electrical conductivity at a solution temperature of 530°C followed by thermal aging of 180°C in comparison to as casted condition [14].…”

The aim of the investigation was to study and predict wear properties of nano Al2O3 reinforced Al composite fabricated by a two-step stir casting method. A pin-on-disc wear device was used to study the wear characteristics. An L9 Orthogonal array was selected as per Taguchi's method to analyze the results and ANOVA was used to examine the impact of applied force, sliding speed, and duration on specific wear rates with "smaller the better" as selection criteria. As per the investigation, applied load significantly influences the particular specific wear rate. Sliding duration is the second most important factor, whereas sliding speed is the factor that has the lowest impact on a given specific wear rate. We created a regression equation with R2 and adj R2 of 99.85% and 99.76% respectively that can estimate the specific wear rate of nano Al2O3 reinforced Al composite. An apple-to-apple comparison between experimental and projected values was built using two confirmation tests, and it revealed an inaccuracy of 2.1% and 6.6%, using a scanning electron microscope. The worn-out surface of the samples with the lowest and greatest specific wear rates was examined and identified with unique oxidation layers and cracks.

“…The fabricated Al composite was used to create cylindrical pins with dimensions of 5 mm in diameter and 12 mm in height. The fabricated Al composite had a Brinell hardness of 139.32 and Vickers hardness of 35.72 respectively [13][14]. All of the pins were thoroughly cleaned and dried before the wear tests.…”
