“…Figure 1 illustrates the uniform distribution of Cr2O3 particles within the aluminum matrix, a critical aspect of the fabricated composite material's quality and performance [43][44][45][46]. The even dispersion of Cr2O3 throughout the matrix is essential for ensuring consistent mechanical and chemical properties across the material, contributing to its overall strength, durability, and resistance to corrosion [47].…”

This paper explores the revolutionary approach of enhancing aluminum composite manufacturing through the integration of Cr2O3 reinforcement using the Friction Stir Technique. The pivotal role of the vertical milling machine in executing Friction Stir Processing (FSP) is emphasized, detailing precise parameters crucial for achieving optimal results. The even dispersion of Cr2O3 throughout the matrix is highlighted as essential for ensuring consistent mechanical and chemical properties, enhancing overall strength, durability, and resistance to corrosion. Experimental findings reveal significant improvements across multiple mechanical properties, including a remarkable 21.56% increase in tensile strength, a notable 36.89% enhancement in hardness, a significant 24.33% improvement in fatigue strength, and a substantial 29.04% increase in wear resistance. These results underscore the effectiveness of Cr2O3 reinforcement via FSP in revolutionizing aluminum composite manufacturing, offering a pathway towards the development of high-performance materials with diverse industrial applications.
