Abstract The impact of silicon carbide (5 wt%) and porcelain (1.5–6.0 wt%) reinforcements on mechanical and tribological features of Al-based hybrid composite (manufactured by metal stir casting) is investigated. A pin-on-disc tribometer was used for experiment and SEM for the characterization of wear for different operating conditions. The hardness of the hybrid composites enhanced approximately by 57% with an increment in porcelain particulates from 1.5 to 6 wt%. However, the wear loss and average coefficient of friction decrease when the porcelain content was added and was found to be minimum at 4.5 wt% porcelain. Hence, the presence of 4.5 wt% porcelain in the Al6061/5SiC hybrid composites produces the best wear properties.

碳化硅和瓷对Al6061基杂化复合材料摩擦学性能的影响

摘要 研究了碳化硅 (5 wt%) 和瓷 (1.5-6.0 wt%) 增强材料对铝基混合复合材料（通过金属搅拌铸造制造）的机械和摩擦学特性的影响。针盘式摩擦计用于实验，SEM 用于表征不同操作条件下的磨损。混合复合材料的硬度提高了大约 57%，瓷颗粒从 1.5% 增加到 6%。然而，当添加瓷器含量时，磨损损失和平均摩擦系数降低，并且发现在 4.5 wt% 瓷器时最小。因此，Al6061/5SiC 混合复合材料中 4.5 wt% 的瓷的存在产生最佳的磨损性能。
