Investigation of abrasion properties of composites produced by alumina reinforcement to the matrix obtained from waste aluminium beverage cans

Aluminium is a widely used matrix material in the production of metal matrix composite materials due to its favourable properties such as low weight and low melting temperature.To improve the properties of the matrix material, metal matrix composite materials are produced by incorporating various reinforcing elements with superior properties.In this study, waste aluminum beverage cans were used as the matrix material.Metal matrix composite materials were produced by stir casting method using alumina particles at concentrations of 0.5, 1 and 1.5 wt%.Wear and hardness tests were performed on the produced metal matrix composite materials and the results were analyzed.The results of the experiments demonstrated that the hardness value of the composite material reinforced with 0.5 wt% alumina particles was 124.83 HV, while the highest hardness value, observed at 1.5 wt%, was 245.51 HV.The lowest percentage weight loss was 1.60%, which was observed in the 1.5% alumina-reinforced composite material.The addition of Al₂O₃ reinforcement resulted in enhanced wear and hardness behaviours.The scanning electron microscope (SEM) images of the composites revealed an increase in particle distribution with elevated reinforcement ratios, indicating a homogeneous distribution of the reinforcement material.
