In this paper, the effect of mechanical vibration with reinforcement particles namely Silicon Carbide (SiC) on microstructure, mechanical properties, wear, and corrosion behaviors of aluminum alloy surface composites fabricated via friction stir processing (FSP) was investigated. The method was entitled friction stir vibration process (FSVP). The results revealed that recrystallized fine grains formed in all processing samples as a result of dynamic recovery and recrystallization, while samples processed in friction stir vibration processing resulted in better grain refinement in the stir zone than in conventional friction stir processing. Compared to conventional friction stir processing, in friction stir vibration processing, the hardness and tensile strength increased due to microstructure modification and better reinforcing distribution. From corrosion analysis, the corrosion resistance of the friction stir vibration processed samples showed a significant increase compared to the friction stir processed specimens. The wear results indicated that the wear resistance of friction stir vibration processed specimens is higher than friction stir processed specimens due to the development of smaller grains and a more homogenous distribution of the strengthening particles as the vibration is applied.

本文研究了增强颗粒碳化硅 (SiC) 的机械振动对搅拌摩擦加工 (FSP) 制备的铝合金表面复合材料的微观结构、机械性能、磨损和腐蚀行为的影响。该方法被命名为摩擦搅拌振动过程（FSVP）。结果表明，由于动态恢复和再结晶，所有加工样品中都形成了再结晶细晶粒，而搅拌摩擦振动加工的样品在搅拌区的晶粒细化效果优于传统的搅拌摩擦加工。与传统的搅拌摩擦加工相比，在搅拌摩擦振动加工中，由于微观结构的改变和更好的增强分布，硬度和抗拉强度增加。从腐蚀分析来看，与搅拌摩擦处理的样品相比，搅拌摩擦振动处理的样品的耐腐蚀性能显着提高。磨损结果表明，搅拌摩擦振动加工试样的耐磨性高于搅拌摩擦加工试样，这是由于施加振动时晶粒更小，强化颗粒分布更均匀。
