Summary: This study investigates the electrodeposition of a three-dimensional nanocone-shaped surface structure on SUS304 stainless steel substrates. Different electrodeposition parameters are used to generate nanocone-shaped Ni coatings. A detailed description of the coating microstructure and composition is proposed for understanding the development of Ni nanocones during electrodeposition. Wetting tests compare the superhydrophobicity of the Ni nanocone coating, while wear tests verify the mechanical stability. The best performance in terms of superhydrophobicity and mechanical properties is achieved after 25 minutes of electrodeposition, where the newly formed Ni nanocones provide an additional air cushion to support surface water droplets and enhance wear resistance. The superhydrophobic Ni coating also exhibits good anti-icing properties. Water droplets freeze starting from the contact points between the water and the sample surface, and surface damage reduces the anti-icing properties of superhydrophobic samples.
