An anti-icing aluminium with a super-hydrophobic surface was fabricated. A static icing system was developed to investigate the process of static icing for samples with different contact angles (CAs), and the contact state was also researched. The results showed that the water droplets’ solidification time on a super-hydrophobic surface was much longer than for other surfaces at the same temperature. A water droplet on the super-hydrophobic surface had a much smaller contact area than on another surfaces. In addition, the air gap between the droplet and the super-hydrophobic surface retarded and prevented any exchange of heat. The temperature affected the transition from the Cassie state to the Wenzel state for super-hydrophobic aluminium.
