摘要
该研究调查了在不同温度下应用射频（RF）溅射 TiO2 涂层来增强 Al6061 合金的疏水性和耐腐蚀性的情况。研究旨在建立涂层工艺与所产生的表面特性之间的相关性。使用表面轮廓仪和测角仪对表面粗糙度和润湿性进行了量化。此外，还进行了化学沸腾和盐雾腐蚀试验，以评估这些过程中的任何地形变化。分析还进一步使用了场发射扫描电子显微镜（FESEM）、能量色散光谱（EDS）和 X 射线衍射（XRD）技术来表征沉积涂层。研究结果表明，与其他温度相比，在 500 °C 下涂敷的 TiO2 涂层具有最高的水接触角和优异的耐腐蚀性。表面表征证实，这种特定的 500 °C TiO2 涂层由于具有疏水性，因此能有效延缓腐蚀，使其在工业应用中经久耐用。
Microstructural, wettability, and corrosion behaviour of TiO2 thin film sputtered on aluminium
The study investigated the application of radiofrequency (RF)-sputtered TiO2 coatings at various temperatures to enhance the hydrophobicity and corrosion resistance of Al6061 alloy. The research aimed to establish a correlation between the coating process and the resulting surface properties. Surface roughness and wettability were quantified with a surface profilometer and goniometer. Additionally, chemical boiling and salt spray corrosion tests were conducted to evaluate any topographical changes during these procedures. The analysis further involved the use of field-emission scanning electron microscopy (FESEM), energy-dispersive spectroscopy (EDS), and X-ray diffraction (XRD) techniques to characterize the deposited coatings. The findings indicated that the TiO2 coating applied at 500 °C exhibited the highest water contact angle and superior corrosion resistance compared to other temperatures. Surface characterization confirmed that this specific TiO2 coating at 500 °C effectively delays corrosion due to its hydrophobic behavior, making it durable for industrial applications.
