One-Step Fabrication of Iron Aluminide Containing Hydrophobic Modified Layers with Enhanced Anti-Corrosion Performance

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