“…Semiconductor properties of the passive film of aluminum or aluminum alloys have been widely reported [32][33][34][35][36][37], and the relevant results indicate that the passive film of aluminum or aluminum alloys presents either n-type [32,[34][35][36] or p-type property [33] depending on the environmental conditions. In order to reveal the effect of Ce content on the semiconductor properties of passive film, the Mott-Schottky curves are measured.…”

The effect of cerium content on the corrosion behavior of Al-Co-Ce amorphous alloys in 0.6 M NaCl solution was investigated by cyclic polarization, Mott-Schottky and X-ray photoelectron spectroscopy techniques. Results indicated that the open circuit potential of Al-Co-Ce amorphous alloys displayed a decreased tendency with the increase in Ce content, and the amorphous alloy with 4 at.% Ce presented both the lowest passive current density and donor density indicating the best corrosion resistance, while adding excess Ce led to the reduced corrosion resistance of Al-Co-Ce alloys. Furthermore, it was found that a low Ce content is beneficial to the formation of a more protective passive film on Al-Co-Ce amorphous alloys, and the corrosion inhibition reactions of Al-Co-Ce alloys in 0.6 M NaCl solution were changed with the increase in Ce content and the detailed reasons were discussed.

“…A significant number of works have been performed to characterize the passive films formed under various conditions [10][11][12][13][14][15][16][17][18]. For example, Bockris and coworkers [10,11] found a two-layer structure of passive film formed on Al alloy in sodium borate solution.…”

“…With respects to the semiconducting property of the passive film formed on Al alloys, there have existed controversial results. Fernandes et al [12] reported that the passive film formed on 2024 Al alloy in a sulphuric-boric bath shows an n-type semiconducting behavior, while Levine et al [13] determined that the passive film on 2024 Al alloy is a p-type semiconductor. Liu et al [19] demonstrated that passive films formed on 3003 Al alloy in air and in Na 2 SO 4 solutions in the absence and presence of chloride ions show an n-type semiconductor in nature.…”

In this work, the passivity and pitting corrosion behavior of 3003 aluminum (Al) alloy in ethylene glycol-water solutions was investigated using various electrochemical measurements, Mott-Schottky analysis and surface analysis techniques. Results demonstrate that the passive film formed on Al alloy contains both Al oxide and Al alcohol, showing an n-type semiconductor in nature. There is an enhanced corrosion resistance of the Al-alcohol film, which is resistant to adsorption of chloride ions. The pitting corrosion of 3003 Al alloy occurs in the solutions containing a low concentration of ethylene glycol only, where the formed film is dominated by Al oxide. Chloride ions attack and replace the oxygen vacancies in the film, resulting in a local detachment of the film from the Al alloy. A galvanic effect exists between Al alloy substrate and the adjacent second phase particles. Pits form when Al alloy substrate is dissolved away and the second phase particles drop off from the substrate.
