Abstract

Aluminum alloys are widely employed due to their advantageous combination of properties, including light weight, corrosion resistance, and mechanical strength. These alloys consist predominantly of aluminum with small additions of other elements aimed at enhancing specific characteristics. Ceramic reinforcements like hBN, SiC, Al2O3, and B4C are added to aluminum alloys to make better their mechanical and wear resistance properties. This practice is frequent and enhances the overall performance of the resulting composite materials. The addition of ceramic reinforcements, incorporated into an aluminum matrix, leads to improved strength and stiffness of the composite. This aspect is particularly advantageous in scenarios necessitating high mechanical strength, such as aerospace and automotive components. The review focuses on the effects of hexagonal boron nitride (hBN) reinforcement on composite materials, particularly aluminum alloys. It emphasizes that the properties of these composites can vary based on several factors, including particle size, weight percentage of hBN, and the processing techniques used. The key points addressed in the study include the impact of hBN reinforcement on mechanical behavior (strength and micro-hardness) and wear resistance behavior of the resulting aluminum alloy composites.
