Abstract

The corrosion protection of 6063 aluminum with film of 3-aminopropyl triethoxysilane was studied in this paper. Electrochemical tests in neutral 3.5% (wt%) NaCl solution, scanning electronic microscopy (SEM), energy dispersive spectroscopy (EDS), and confocal laser scanning microscope (CLSM) were performed. The result showed that the silane films could offer unexceptionable corrosion resistance to metal. A highly crosslinked and dense interfacial layer formed on the surface of the metal, which makes the substrate and the coating firmly combined to reduce the corrosion current density and inhibit the occurrence of corrosion. The film with bridging group had excellent hydrophobicity which can heavily restrict corrosion product proceeds at the interface.
