Abstract
The comparative analysis of Al2O3 coatings and effect of surface morphology on the wettability properties were discussed. It was shown that it is possible to obtain high hydrophilic parameters with a contact angle value up to 17–20° using high values of current density, anodizing time, and electrolyte temperature by adjusting the electrochemical conditions. It was seen that this type of modified Al2O3 structures provides direct experimental evidence for the theory of threedimensional capillaries regarding superhydrophilicity.
