Electrochemical Characteristics of the Self-Assembly Film on 6061 Aluminum Alloy

Abstract:

The SAMs was prepared on aluminum alloy by self-assembly membrane technology. The surface morphology of the SAMs was analyzed by scanning electron microscopy (SEM). The electrochemical properties of the SAMs and bare Al alloy samples were researched by Potentiodynamic polarisation and electrochemical impedance spectroscopy in a 3.5-wt.% NaCl solution. The results showed that corrosion current density of the sample with the SAMs was 3.033×10^-9 Acm^-2. The impedance of SAMs was three times than the bare Al alloy. The SAMs had better corrosion resistance than the sample of the bare aluminum alloy substrate.
