Aluminium alloys have been extensively used in industries due to their light weight, resistance to corrosion and high strength-to-weight ratio. The range of properties that can be imparted to them is remarkable. The addition of alloying elements to aluminium helps to improve their properties which show better tribological characteristics. In the present study, aluminum is reinforced with different weight percentages of zirconium. Three different samples of pin-shaped and coin-shaped specimens were fabricated through the casting process by varying Zirconium as 0%, 1.47% and 2.07% by weight in commercially available aluminium. Wear and hardness test on the fabricated samples were performed using a pin-on-disc tribometer and Brinell Hardness tester. The optical emission spectroscopy shows an increase in the zirconium composition in different specimens and higher zirconium composition specimens show improved wear resistance and a decrease in hardness as the zirconium content increases. A decreasing trend in the magnitude of specific wear rate was seen from 0.22 to 0.15 with varying Zirconia composition. Brinell's Hardness Number also decreases from 21.76 to 16.7 BHN as the zirconium content increases. Because of the above-mentioned benefits, the fabricated material can be used in industries where the component is subjected to high wear.
