The research article addresses the reciprocating wear behaviour of hybrid AA7075 reinforced with boron carbide and boron nitride through a stir-casting technique. The experiment involved varying wt.% of the secondary particle boron carbide (3, 6 and 9) while boron nitride (3) was kept as constant. The hybrid composites were characterised using scanning electron microscopy coupled with energy dispersive spectroscopy. The hardness and tensile behaviour of the hybrid composites were evaluated. Reciprocating wear behaviour of the hybrid composites were examined using a tribometer by varying the wear parameters such as load and sliding distance. The results revealed that AA7075/6boron carbide/3boron nitride had better hardness, tensile and wear properties. The surface morphology of the wear samples was analysed using SEM.

该研究文章讨论了通过搅拌铸造技术用碳化硼和氮化硼增强的混合 AA7075 的往复磨损行为。该实验涉及改变二次粒子碳化硼（3、6 和 9）的重量百分比，而氮化硼（3）保持不变。使用扫描电子显微镜结合能量色散光谱对混合复合材料进行表征。评估了混合复合材料的硬度和拉伸性能。通过改变载荷和滑动距离等磨损参数，使用摩擦计检查混合复合材料的往复磨损行为。结果表明，AA7075/6碳化硼/3氮化硼具有更好的硬度、拉伸和磨损性能。使用SEM分析磨损样品的表面形貌。
