AA5083 alloys with V additions were produced in the powder form by high-energy ball milling and consolidation by spark plasma sintering and cold compaction. X-ray diffraction and energy dispersive X-ray spectroscopy analysis indicated the formation of supersaturated solid solution and grain refinement below 100 nm. Corrosion behavior was investigated using electrochemical impedance spectroscopy, cyclic potentiodynamic polarization, and immersion corrosion tests followed by surface analysis. The composition of the passive film was obtained via X-ray photoelectron spectroscopy. The corrosion resistance of the AA5083 was significantly improved due to the addition of V and high-energy ball milling.

通过高能球磨并通过火花等离子体烧结和冷压实进行固结，可以制成粉末形式的具有V添加的AA5083合金。X射线衍射和能量色散X射线光谱分析表明，过饱和固溶体的形成和100 nm以下的晶粒细化。使用电化学阻抗谱，循环电势极化和浸没腐蚀测试，然后进行表面分析，研究腐蚀行为。通过X射线光电子能谱获得无源膜的组成。由于添加了V和高能球磨，AA5083的耐蚀性得到了显着改善。
