Abstract

Highlights: The AC treatment increased η% of the mixed self-assembled monolayer. Organic molecules may be re-orientated in the alternating electric field. The AC-treated effects depended on the AC-treated potential. The AC-treated effects were caused by the formation of a complex compound. The AC-treated effects were also caused by the reduction of the oxide film. Abstract: The inhibitive effects of alternating current-treated (AC-treated) mixed self-assembled monolayer (SAMHL/DT ) with 2-(Pyridin-2-yliminomethyl)-phenol (HL) and dodecanethiol (DT) on copper corrosion have been studied by using the scanning electrochemical microscope (SECM) combined with Tafel and electrochemical impedance spectroscopy (EIS) methods When the AC-treated potential is applied in the cathodic region, the inhibition efficiency increases, and the pitting dynamic processes are inhibited. All the results reveal that the AC-treated effects are related to both the formation of complex compounds and the reduction of the oxide film on the surface of copper.
