Abstract

TiO₂ nanotubes (TNT) were grown on titanium foil through anodization in a two-electrode setup, followed by decoration with metal nanoparticles using a simple, cost-effective electrodeposition method. Surface wetting studies showed that silver coated TNT (Ag-TNT) had enhanced hydrophobicity with a contact angle of 145.5°. In potentiodynamic polarisation tests, it exhibited superior corrosion resistance compared to titanium and TNT, with a high corrosion potential of 0.156 V and a low current density of 3.16 × 10⁻⁹ A/cm², indicating solid potential for marine applications. In comparison with TNT, cobalt coated TNT (Co-TNT) offered moderate corrosion protection, while gold coated TNT (Au-TNT) and nickel coated TNT (Ni-TNT) showed lower corrosion resistance, likely due to uneven metal deposition.

通过电沉积金属纳米粒子改善TiO2纳米管表面性能，得到疏水耐腐蚀表面

通过双电极阳极氧化在铝箔上生长TiO2纳米管（TNT），然后采用简单、经济的电沉积方法用金属纳米颗粒进行修饰。表面润湿研究表明，镀银TNT （Ag-TNT）的疏水性增强，接触角为145.5°。在动电位极化测试中，与钛和TNT相比，它表现出更好的耐腐蚀性，具有0.156 V的高腐蚀电位和3.16 × 10−9 a /cm2的低电流密度，表明固体潜力用于船舶应用。与TNT相比，钴包覆TNT （Co-TNT）具有中等的防腐性能，而金包覆TNT （Au-TNT）和镍包覆TNT （Ni-TNT）的耐腐蚀性较低，这可能是由于金属沉积不均匀所致。
