The corrosion can be widely found in metal materials, which greatly restricts the utilization of metal. Super-hydrophobic coating, known as a material surface with a contact angle greater than 150°, which has been gradually used as a protect film on the surface of metallic material in recent studies. The article presents a review of recent literatures which covers aspects of using super-hydrophobic film as a smart protect surface to protect metallic materials. Different super-hydrophobic systems obtained by different preparation technologies were introduced in this work. Overall, the obtained results indicate that the super-hydrophobic coatings can effectively enhance the anti-corrosion ability of the metal surface, which supports the possibility of using super-hydrophobic film as a substitute of chromate-containing passivation coatings to protect metallic substrates.
Key words: super-hydrophobic coating / metallic material / corrosion protection
