Figure 1

Wettability of the laser-textured Ti-6Al-4V samples. (a) S1 and (b) S2 immediately after the laser texturing. (c) S1.1 after 24 h of annealing at 100 °C in contaminated Furnace #1. (d) S1.2 and (e) S2.2 after an additional 24 h of annealing at 100 °C in contaminant-free Furnace #2. (f) S1.3 and (g) S2.3 after an additional 2 h of annealing at 350 °C in contaminant-free Furnace #3. Panels a, b, e, f, and g show the top view, acquired 2 s after the contact between the water droplet and the surface, wheras panels c and d show the side view. The same scale shown at the bottom applies to all images.
