Abstract

Al-Cu alloy has been widely applied to automobile products due to its light weight and high strength, but pitting corrosion easily occurs due to intermetallic compounds (IMCs) in Al-Cu alloy. Anodizing process has been conventionally performed to improve the corrosion resistance of Al-Cu alloy surface. However, IMCs in Al-Cu alloy lead to defects in anodic oxide film. In this study, refinement of IMCs in Al-Cu alloy surface by large-area EB irradiation was proposed. Experimental results show that reflectance and corrosion resistance of anodic oxide film formed on Al-Cu alloy surface are improved by refinement of IMCs with the EB irradiation.

大面积电子束辐照改进铝铜合金阳极氧化膜特性

铝铜合金以其质量轻、强度高的特点在汽车产品中得到了广泛的应用，但由于铝铜合金中含有金属间化合物（IMCs），易发生点蚀。阳极氧化是提高铝铜合金表面耐蚀性的传统方法。然而，铝铜合金中的IMCs会导致阳极氧化膜的缺陷。本研究提出了采用大面积电子束辐照对铝铜合金表面IMCs进行细化的方法。实验结果表明，在EB辐照下对IMCs进行细化后，Al-Cu合金表面形成的阳极氧化膜的反射率和耐蚀性都得到了提高。
