Abstract
The procedures of fabricating s functional composite coating with properties of anticorrosion, hydrophobicity, and oleophobicity on AZ91D magnesium alloy substrates are implemented. A SiOx anticorrosion layer is firstly fabricated by an atmospheric pressure plasma jet (APPJ) system with tetraethoxysilane as the precursor, and subsequently 1H,1H,2H,2H-perfluorooctyltriethoxysilane (FAS-13) is coated on SiOx/AZ91D samples by a spin coater to alter the surface hydrophobicity. The APPJ-deposited SiOx film has a hydrophilic surface with a surface energy of 68.4 mN m−1, while the FAS-13 coating on the SiOx/AZ91D sample turns into the hydrophobic surface with a lower surface energy of 12.49 mN m−1, proving an improved anticorrosion performance by electrochemical impedance spectroscopy measurements. Tests of adhesion and oil contact angle also reveal the reliability of this coating. These results show the feasibility of the FAS-13/SiOx composite coating for improving the corrosion resistance and the surface properties with hydrophobicity and oleophobicity is practically achieved.
