通过高能球磨生产的Al-V合金粉末被冷喷涂到AA2024-T3基体上。冷喷涂合金的耐腐蚀性能，以腐蚀电流密度和点蚀电位为代表，明显高于基体。此外，零电阻电流表测试表明，涂层对基材来说是阳极的，这将在涂层击穿的任何情况下提供阴极保护。涂层的耐磨性几乎是基体的四倍。
An Al-V alloy powder produced by high-energy ball milling has been cold sprayed on an AA2024-T3 substrate. The corrosion resistance of cold sprayed alloy, represented by the corrosion current density and pitting potential, was significantly higher than the substrate. Furthermore, a zero-resistance ammeter test revealed that the coating was anodic to the substrate, which would provide cathodic protection in any event of coating breakdown. The wear resistance of the coating was almost four times higher than that of the substrate.
