“…In the marine condition, the severity of corrosion largely depends on the penetration depth of corrosive ions. Building protective coatings is the most common way to protect marine construction and restrict the penetration of corrosive ions [1][2][3][4].…”

“…With features of low density, high strength and excellent corrosion resistance, iron aluminides, which consist of FeAl, Fe 3 Al, Fe 5 Al 2 and Al 13 Fe 4 (could be referred to Al 3 Fe), are regarded as a kind of practical structural and fascinating candidate material for barrier materials applied in marine nuclear power generation systems and petrochemical industries [1,[5][6][7]. Given the potential applications of iron aluminide, investigations to fabricate iron aluminide modified surface layers have been conducted, and several methods including Mechanical Alloying (MA), Electron Beam Physical Vapor Deposition (EB-PVD) and Laser Cladding (LC) have been developed for the fabrication of iron aluminide in recent years.…”

An iron aluminide modified layer prepared by a novel powder mixed electrical discharge alloying (PMEDA) process with a green compact aluminum electrode is conducted to improve the corrosion performance of work pieces. The phase composition and microstructure of the modified samples are analyzed by Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS), X-ray Diffraction (XRD) and Transmission Electron Microscope (TEM). Corrosion performance is investigated by the electrochemical workstation and the mechanism of corrosion resistance improvement is explored. The 12A modified samples exhibit a hydrophobic 102.4° contact angle, while showing 669% and 40% less corrosion current density in the simulated aqueous corrosion condition in comparison with the non-treated and non-hydrophobic modified samples, respectively. These enhanced performances are attributed to the synchronization of a hydrophobic surface, corrosion-proof iron aluminide and a dense, well-distributed modified layer.
