Abstract

With the increasing demand for lightweight and high-strength materials, aluminium alloy composites have shown promising properties for structural applications. This work investigates the fabrication of AA6063/Si3N4 nanocomposites through the friction stir processing (FSP) route. The study evaluates the effect of the volume fraction of Si3N4 on the mechanical properties, fretting wear, and corrosion behaviour of the aluminium composite. The microstructure, distribution of the reinforcement, and phase changes were characterized using field emission scanning electron microscopy images and X-ray diffraction. The results indicate that the FSP route is an effective method for producing AA6063/Si3N4 nanocomposites which exhibit improved mechanical properties and wear resistance compared to the base material. Additionally, the corrosion resistance of the composite was found to be enhanced to that of the base material. In comparison with the base material, a significant improvement of 81% in hardness and 47.2% in tensile strength was observed in the 10% Si3N4 AMC. These findings demonstrate the potential for using FSP to produce high-performance nanocomposites for various industrial applications.

研究通过摩擦搅拌工艺制造的 AA6063/Si3N4 纳米复合材料的机械性能、摩擦磨损和腐蚀行为
随着对轻质高强度材料的需求不断增加,铝合金复合材料在结构应用方面显示出了良好的性能。本研究探讨了通过摩擦搅拌加工(FSP)路线制造 AA6063/Si3N4 纳米复合材料的方法。研究评估了 Si3N4 体积分数对铝复合材料机械性能、摩擦磨损和腐蚀行为的影响。利用场发射扫描电子显微镜图像和 X 射线衍射对微观结构、增强体分布和相变进行了表征。结果表明,FSP 路线是生产 AA6063/Si3N4 纳米复合材料的有效方法,与基体材料相比,AA6063/Si3N4 纳米复合材料具有更好的机械性能和耐磨性。此外,复合材料的耐腐蚀性也比基体材料更强。与基础材料相比,10% Si3N4 AMC 的硬度和拉伸强度分别显著提高了 81% 和 47.2%。这些发现证明了使用 FSP 生产高性能纳米复合材料在各种工业应用中的潜力。
