Effect of Storage Conditions on Ti-6Al-4V Surface Wettability
The relationship between storage conditions and wettability of annealed micro-rough samples was investigated in this study. Micro-roughness (2.45 ± 0.43 μm) was obtained through sandblasting and acid-etching in sulfuric acid and hydrogen peroxide. Non-annealed samples (control) and samples annealed at 400 °C and 600 °C were used. In order to investigate the influence of storage conditions on the surface wettability, Ti-6Al-4V disks were 1) wrapped in Kimwipe inside a plastic bag, 2) stored in petri-dishes containing 20 mL deionized water (DI-water) at room temperature, and 3) stored in petri-dishes containing 20 mL cold DI-water (8 ± 2 °C). Surface characterization was conducted using water contact angle (WCA) measurements, white light interferometry (WLI), and fourier transform infrared (FTIR) spectroscopy. Disks immersed in DI-water maintained higher wettability when compared to Kimwipe groups over the course of 34 days regardless of the storage temperature. In addition, samples annealed at 600 °C showed superior wettability due to the rutile nature of the oxide film.
