摘要

本研究制备了一种环保金属基体,考察了蛋壳粉和CaCO3颗粒对再生铝抗拉强度和硬度的影响。采用了由再生铝制成的基体。碳酸钙和蛋壳作为研究的增强材料。蛋壳和碳酸钙的重量百分比分别为2%、4%和8%。样品由砂型铸造而成。结果表明,蛋壳和碳酸钙对再生铝的硬度、屈服和极限抗拉强度均有积极影响。硬度值随蛋壳含量的增加而提高。在碳酸钙含量为2%时达到最大硬度。同样,CaCO3添加量为2%时,屈服强度提高幅度最大,蛋壳添加量为8%时,拉伸强度提高幅度最大。为了获得更好的结果,最好使用比本研究中使用的更细的蛋壳。由铝基制成的复合材料具有优异的机械和物理特性。需要克服的最具挑战性的障碍是金属基复合材料的成本。蛋壳是一种副产品,可以作为一种轻量级的、负担得起的加固形式。一种消除这种副产品,改善复合材料特性,降低铝复合材料成本的方法是使用蛋壳。通过对比研究,确定了添加农副产蛋壳和商用CaCO3增强材料对425 m尺寸鸡蛋和CaCO3分别作为增强材料的再生铝基特性的影响,从而形成有利于环境的金属基。

Assessment of eggshell and CaCO3 reinforced recycled aluminium green metal matrix
In this study, an environmentally friendly metal matrix was prepared, and the influence of eggshell powder and CaCO3 particles on the tensile strength and hardness of recycled aluminium were assessed.A matrix made of recycled aluminium was employed. Calcium carbonate and eggshells served as the study's reinforcing materials. Separately, weight percentages of 2, 4, and 8% of eggshell and calcium carbonate were used. The samples were made by sand-casting.The results showed that both eggshell and calcium carbonate positively affect the hardness, yield, and ultimate tensile strength of recycled aluminium. The hardness values were improved as the percentage of the eggshell increased. The maximum hardness was achieved at 2% calcium carbonate. Similarly, the highest improvement of yield strength was for 2% CaCO3 addition, while the highest tensile strength was obtained at 8% eggshell addition.To get better results, it would be desirable to use finer eggshells than those utilized in this study.Composites made with an aluminium matrix exhibit exceptional mechanical and physical characteristics. The most challenging obstacle to overcome is the cost of metal matrix composites. Eggshells are a by-product that could be employed as a lightweight, affordable form of reinforcement. One way to get rid of this by-product, improve composite characteristics, and lower the cost of aluminium composite is to use eggshells.A comparative investigation was carried out to determine the effects of adding agricultural by-product eggshell, and commercial CaCO3 reinforcement material on the characteristics of recycled aluminium matrix integrated 425 m sized eggshell and CaCO3 separately as a reinforcement material to create a metal matrix that is beneficial to the environment.
