Abstract:

The novel dodecyltriethoxysilane(DTES)/graphene oxide(GO) composite film is prepared via onestep electrodeposition onto 430 stainless steels. Raman spectroscopy measurement and scanning electron microscopy(SEM) measurement suggest efficient encapsulation of GO. Both electrochemical impedance spectroscopy measurement and polarization tests show that composite films have effectively improved the corrosion resistance of 430 stainless steel in 3.5% mass fraction of NaCl solution. The excellent corrosion resistance of well-dispersed GO fill the crack of silane matrix, and the corrosion medium encounter a more tortuous path in traversing in silane matrix, resulting in an improved corrosion protection performance of the composite films.
