Abstract

The adsorption and corrosion inhibition behavior of 1–tetradecylphosphonic acid self-assembled monolayers on the differently structured surfaces of 2024 and 1060 aluminum alloys were investigated by contact-angle measurement, potentiodynamic polarization, electrochemical impedance spectroscopy, and scanning electron microscopy coupled with energy-dispersive spectroscopy. The electrochemical experiments showed that a 4 h modification of 2024 and 1060 alloys resulted in a maximal inhibition efficiency. Independent of assembly time, the desorption of the tetradecylphosphonic acid molecules provoked by anodic polarization to a certain degree resulted in the acceleration of the anodic dissolution reaction. The inhibition of the self-assembled monolayers for the 1060 alloy was more prominent than for the 2024 alloy. This is consistent with the contact-angle values, supporting the conclusion that TDPA formed a more closely packed SAM on the surface of the 1060 alloy than of the 2024 alloy. Scanning electron microscopy/energy dispersive X-ray spectroscopy results directly revealed the inhibition effect of the monolayers on the primary corrosion stage of these two alloys.
