The friction stir joining experiment was performed on a 6061-T6 aluminum alloy sheet 1 mm thick by optimization of different process parameters, and the microstructure and performance analysis of the joint area using a metallographic microscope, friction and wear testing machine, and scanning electron microscope were evaluated. The results show that the crystalline grains in the joint area of the specimen were refined under a given parameter, and the precipitation of the reinforcing phase improved the performance of the joint area. The best parameters for grain refinement were found to be a rotation speed of 8000 rpm and a traverse speed of 300 mm/min. The specimen obtained at 15,000 rpm and 200 mm/min exhibited the smallest milling weight loss. The smallest average friction coefficient of the specimen was observed at 8000 rpm and 300 mm/min. The friction weight loss trend of the specimens obtained under each parameter was basically the same as the friction coefficient. The wear form of each specimen was found to be mainly the adhesive wear, accompanied by the abrasive one.

通过优化不同的工艺参数，对厚度为1 mm的6061-T6铝合金薄板进行了摩擦搅拌接合实验，并使用金相显微镜，摩擦磨损试验机和扫描电子显微镜对接合部位的组织和性能进行了分析。被评估。结果表明，在给定的参数下，试样接缝区域的晶粒得以细化，强化相的析出改善了接缝区域的性能。发现晶粒细化的最佳参数是8000 rpm的旋转速度和300 mm / min的移动速度。以15,000 rpm和200 mm / min的速度获得的样品显示出最小的研磨失重。在8000 rpm和300 mm / min下观察到样品的最小平均摩擦系数。在每个参数下获得的试样的摩擦失重趋势与摩擦系数基本相同。发现每个样品的磨损形式主要是粘合磨损，伴随着磨料磨损。
