Abstract

This work examines the mechanical and wears traits of metal matrix composites (MMCs) based on AA6061-T6 reinforced with yttrium oxide (Y₂O₃) and egg shell powder (ESP). The composites were fabricated with varying reinforcement contents (ESP: 3–6 wt%, Y₂O₃: 2 wt%), and their effects on tensile strength (TS), hardness (HV), impact strength, elongation, wear rate, and friction coefficient were analyzed. Experimental results indicate a significant improvement in mechanical characteristics when reinforcements are added. While hardness and impact strength increased by 28.83 % and 23.33 %, respectively, tensile strength showed a maximum rise of 22.58 %. A reduction in elongation of up to 25 % was observed, indicating increased brittleness. Wear rate analysis demonstrated a substantial decrease with the lowest wear rate recorded at 2.978 mm³/min reflecting enhanced wear resistance, The friction coefficient also decreased, highlighting the role of ESP and Y₂O₃ in improving tribological performance. The findings confirm that the addition of ESP and Y₂O₃ enhances the overall performance of AA6061-T6, making it a promising material for structural and wear-resistant applications.

aa6061 -蛋壳粉- y2o3金属基复合材料力学与磨损研究

本文研究了以氧化钇（Y2O3）和蛋壳粉（ESP）增强的AA6061-T6金属基复合材料（MMCs）的力学和磨损特性。研究了不同增强量（ESP: 3-6 wt%, Y2O3: 2 wt%）对复合材料抗拉强度（TS）、硬度（HV）、冲击强度、伸长率、磨损率和摩擦系数的影响。实验结果表明，加入增强材料后，其力学性能得到了显著改善。硬度和冲击强度分别提高28.83%和23.33%，抗拉强度最大提高22.58%。观察到延伸率降低了25%，表明脆性增加。磨损率分析显示，ESP和Y2O3的磨损率大幅下降，最低磨损率为2.978 mm3/min，反映出耐磨性的增强，摩擦系数也有所下降，突出了ESP和Y2O3在改善摩擦学性能方面的作用。研究结果证实，ESP和Y2O3的加入提高了AA6061-T6的整体性能，使其成为一种有前景的结构和耐磨材料。
