Aluminum Alloy Surface

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.

This Four passes processing to the thermal spray aluminum coating on the aluminum alloy surface,based on friction stir processing (FSP). Applications SEM, EDS and micro hardness testing to analysis the coatings that have been processed and haven't been processed. The results show that , after the friction stir processing,dense ultrafine grained aluminum with the sizes less than 200nm is obtain ,and replace original laminated and porous coating . Fusion utilizes between the coating and the substrate, the gap between coating and substrate have disappear. The alloy elements in the substrate diffuse to the coating.
