The design of color-tuned magnesium alloy with anticorrosive properties and damping capacity was created by means of a simple and inexpensive method. The vertically self-aligned nano- and microsheets were formed on magnesium alloy AZ31 by a chemical-free immersion process in ultrapure water at a temperature of 120 °C, resulting in the color expression. The color changed from silver with metallic luster to some specific colors such as orange, green, and orchid, depending on the immersion time. The color-tuned magnesium alloy showed anticorrosive performance and damping capacity. In addition, the colored surface with minute surface textures was modified with n-octadecyltrimethoxysilane (ODS), leading to the formation of color-tuned superhydrophobic surfaces. The corrosion resistance of the color-tuned superhydrophobic magnesium alloy was also investigated using electrochemical potentiodynamic measurements. Moreover, the color-tuned superhydrophobic magnesium alloy showed high hydrophobicity not just for pure water but also for corrosive liquids, such as acidic, basic, and some aqueous salt solutions. In addition, the American Society for Testing and Materials (ASTM) standard D 3359-02 cross cut tape test was performed to investigate the adhesion of the color-tuned superhydrophobic film to the magnesium alloy surface.
通过简单且廉价的方法，设计出具有耐腐蚀性能和阻尼能力的彩色可调镁合金。通过在 120°C 的超纯水中进行无化学处理的浸渍工艺，在镁合金 AZ31 上形成垂直自对准的纳米和微片，从而实现颜色表达。颜色会从具有金属光泽的银色变为橙色、绿色和兰花色等特定颜色，具体取决于浸渍时间。彩色可调镁合金具有耐腐蚀性能和阻尼能力。此外，用正十八烷基三甲氧基硅烷（ODS）对具有微小表面纹理的彩色表面进行改性，形成彩色可调超疏水表面。通过电化学动电位测量研究了彩色可调超疏水镁合金的耐腐蚀性。此外，彩色可调超疏水镁合金不仅对纯水而且对腐蚀性液体（如酸性、碱性和一些盐水溶液）表现出高疏水性。此外，还进行了美国材料试验协会（ASTM）标准 D 3359-02 十字切割带试验，以研究彩色可调超疏水膜在镁合金表面的附着力。
