The present work investigates the tribological wear characteristics (pin-on-disc) of Al6061composite that has been fabricated via stir casting route of liquid metallurgy technique with varying content of aluminium oxide(Al₂O₃), zirconia sand (ZrSiO₄), silicon carbide (SiC) and rice husk ash (RHA) as reinforcement. The test observations can be observed and appreciated that increasing the reinforcement percentage, the properties like density and hardness increased significantly and monolithically. The dry sliding pin-on-disc (POD) wear test is performed using configuration tribometer by various parameters at 50 N load, 600 RPM, 25 min, and the test results state that composites have greater wear resistance. These tribological wear characteristics are then optimized using the L16 orthogonal array Taguchi method, where a weight loss model was created in terms of applied load, abrasive grain size, which revealed that the reinforcement’s weight per cent is the highest influencing factor. Basically, the Al6061 is comparatively soft, and as per dry sliding POD wear concern at the applications of stringers, aircraft wings, seat tracks, floor breams, fuselage of an aircraft’s, the wear resistance plays a crucial role in relative movement at contact surfaces; hence, the present work focused on developing Al6061–SiC/Al₂O₃/RHA/ZrSiO₄ metal matrix hybrid composites with enhanced tribological and mechanical properties. Of all the mixtures, the composites having the optimum percentage of reinforcement materials showed improved properties. To do the tribological wear analysis, samples are slide against SiC abrasive grit, and the worn-out surface is then analysed using scanning electron microscope and EDS. Experimentally, it was found that applied load and sliding distance have an almost negligible effect on wear, whereas the abrasive grain size has the highest impact on wear. The predicted material loss of the hybrid composite samples was found to lie near by that of the experimentally observed ones.

本工作研究了Al6061复合材料的摩擦磨损特性（pin-on-disc），该复合材料通过液态冶金技术的搅拌铸造路线制造，具有不同的氧化铝（Al ₂ O ₃）、氧化锆砂（ZrSiO _{4 ）含量。})、碳化硅 (SiC) 和稻壳灰 (RHA) 作为增强材料。可以观察到测试观察结果并认识到，增加增强百分比，密度和硬度等性能显着且整体增加。干式滑动销盘（POD）磨损测试是使用配置摩擦计在50 N负载，600 RPM，25 min下进行的各种参数，测试结果表明复合材料具有更大的耐磨性。然后使用 L16 正交阵列 Taguchi 方法优化这些摩擦磨损特性，在该方法中，根据施加的载荷、磨料粒度创建了一个重量损失模型，这表明增强体的重量百分比是最高的影响因素。基本上Al6061比较软，根据干滑POD在纵梁、飞机机翼、座椅轨道、地板梁、飞机机身应用中的磨损问题，耐磨性在接触面的相对运动中起着至关重要的作用；因此，目前的工作重点是开发 Al6061–SiC/Al₂ O ₃ /RHA/ZrSiO ₄金属基杂化复合材料，具有增强的摩擦学和机械性能。在所有混合物中，具有最佳增强材料百分比的复合材料表现出改进的性能。为了进行摩擦磨损分析，样品在 SiC 磨粒上滑动，然后使用扫描电子显微镜和 EDS 分析磨损表面。实验发现，外加载荷和滑动距离对磨损的影响几乎可以忽略不计，而磨粒尺寸对磨损的影响最大。发现混合复合材料样品的预测材料损失接近于实验观察到的材料损失。
