  5. 4. Hydrophobic and superhydrophobic coatings for corrosion protection of steel

    Författare :Lina Ejenstam; Per M. Claesson; Agne Swerin; Jinshan Pan; Orlando Rojas; KTH; []
    Nyckelord :Superhydrophobic coating; hydrophobic coating; corrosion protection; contact angles; electrochemical measurements; surface characterization; Kemi; Chemistry;

    Sammanfattning : Since metals in general, and steels in particular, are vital construction materials in our modern society, the corrosion protection of said materials is of great importance, both to ensure safety and to reduce costs associated to corrosion. Previously, chromium (VI) and other harmful substances were effectively used to provide corrosion protection to steel, but since their use was heavily regulated around year 2000, no coating has yet been developed that, in a fully satisfactory manner, replaces their corrosion protective properties.
