Aluminum and its alloy are reactive materials and are prone to corrosion in aqueous environment especially in seawater [1]. Metals corrosion products may be induced contamination in various environments. Therefore, it is necessary to improve corrosion resistance of metals. The use of superhydrophobic surfaces is one of the original techniques for protection against corrosion [2]. In low adhesive superhydrophobic surfaces, water contact angle (WCA) is upper than 150° and sliding angle (SA) is lower than 10°. Fabrication of suitable roughness is a fundamental step for acquiring superhydrophobic surfaces. For this purpose, we deposited ZnO nanoparticles on Al surface using ultrasound approach. Surface energy reduction as next step was done using eco-friendly stearic acid. The potentiodynamic measurements demonstrate that superhydrophobic Al can lead to advance the corrosion resistance. Scanning electron micrograph (SEM) and energy-dispersive X-ray spectroscopy (EDX) confirmed condense particle deposition on Al substrate using ultrasound. The crystallite evaluation of deposited ZnO nano particles is carried out using X-ray diffractometer (XRD). Finally, for STA grafting verification on Al surface, Fourier transform infrared in conjunction with attenuated total reflection (FTIR-ATR) is used as a practical technique.
