In this investigation, the AA5083/316 stainless steel (ss) surface composite was generated by the friction stir processing (FSP) with the aim of improving the mechanical properties, the corrosion and tribological performances of the composite. The FSP process was conducted at different tool pass numbers (1-P, 2-P, and 4-P) and a constant tool rotational (900 rpm) and travel (85 mm/min) speeds. To analyze the microstructure of the samples, optical (OM) and scanning electron microscopes (SEM) were employed to characterize the scattering of the 316 stainless steel (ss) particles within the AA5083 matrix. It was found that multi-pass FSP resulted in substantial grain refinement from 7.02 to 5.89 μm and better scattering of the reinforcement in the AA5083 Al matrix. Results also indicated that the mechanical and wear properties of the composite layers were enhanced by increasing the pass number from 1-pass to 4-pass, which can be credited to the formation of finer 316 stainless steel (ss) particles appropriately dispersed in the Al substrate. Furthermore, the results depicted that the corrosion resistance of the samples is enhanced with the increase of pass number.

在这项研究中，AA5083/316 不锈钢 (ss) 表面复合材料是通过搅拌摩擦加工 (FSP) 生成的，目的是提高复合材料的机械性能、腐蚀和摩擦学性能。FSP 工艺是在不同的刀具通过次数（1-P、2-P 和 4-P）和恒定的刀具旋转（900 rpm）和行进（85 mm/min）速度下进行的。为了分析样品的微观结构，使用光学 (OM) 和扫描电子显微镜 (SEM) 来表征 316 不锈钢 (ss) 颗粒在 AA5083 基体中的散射。结果发现，多道次 FSP 导致从 7.02 到 5.89 μm 的显着晶粒细化和 AA5083 Al 基体中的增强物更好的分散。结果还表明，通过将道次数从 1 道次增加到 4 道次，复合层的机械和磨损性能得到了增强，这可以归功于形成了更细的 316 不锈钢 (ss) 颗粒，适当地分散在铝中。基质。此外，结果表明，随着道次的增加，样品的耐腐蚀性能增强。
