Abstract

Metal corrosion has brought huge losses to human society, so it is of great significance to study the corrosion and protection of materials. To improve the corrosion resistance of Q235 carbon steel, the work aims to prepare the SiO2/PDMS super-hydrophobic coating on the surface of Q235, and discuss the corrosion resistance and mechanism of the composite coating.

Key words

super-hydrophobic; anti-corrosion; composite coating; Q235 carbon steel; polydimethylsiloxane; SiO2
