| Abstract: |
| A stable super-hydrophobic film was fabricated on silicon based aluminum coating by myristic acid chemically adsorbed on micro / nano composite structure constructed by cathodic etching process. The formation mechanism, microstructure and corrosion behavior of the film were characterized. The results suggest that the surface of the film is composed of micropores and coral-like structures with nano-sized floccules on their surface after treatment of cathodic etching. The surface of the myristic acid modified coating achieves super-hydrophobic and the myristic acid is chemically adsorbed on the surface. The super-hydrophobic treatment enhances the corrosion resistance of the coating greatly, and the corrosion impedance efficiency achieves as high as 98 . 9 % . |
