摘要
在不同温度下,在Al6061合金表面射频溅射二氧化钛涂层,以改善其疏水性和耐腐蚀性,旨在了解射频溅射工艺对二氧化钛涂层性能的影响规律.使用表面轮廓仪和测角仪测量表面粗糙度和润湿性,通过化学沸腾法和盐雾腐蚀法过程中形貌变化来研究耐腐蚀性能.使用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)技术来表征涂层.结果表明,与其他温度相比,在500℃得到的二氧化钛涂层具有最高的水接触角和优越的耐腐蚀性.表面表征证实了这种500℃得到的二氧化钛涂层由于其好的疏水性,有效地延缓了腐蚀,使其持久用于工业应用.
Abstract
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℃exhibited the highest water contact angle and superior corrosion resistance compared to other temperatures.Surface characterization confirmed that this specific TiO2 coating at 500℃effectively delays corrosion due to its hydrophobic behavior,making it durable for industrial applications.
