Investigating the impact of nanostructured Nb2O5-based coating on the corrosion and corrosion-fatigue resistance of 2198-T8 aluminium alloy
| Resumo: | This investigation examined the efficacy of Nb₂O₅-based coatings, deposited by using the reactive sputtering technique, on the corrosion and corrosion-fatigue behaviour of 2198-T8 aluminium alloy used as aircraft material. Global corrosion behaviour was accessed by Open Circuit Potential (OCP), Potentiodynamic Polarization curves (PPc) and Electrochemical Impedance Spectroscopy (EIS) techniques in 0.6 mol L⁻1 NaCl solution. Fatigue crack growth (FCG) tests were conducted under controlled loading conditions in both air and saline environments. Comprehensive structural and morphological characterisations were performed using advanced microscopy and spectroscopy techniques, including Atomic Force Microscopy (AFM), Scanning Electron Microscopy/Energy Dispersive X-ray Spectroscopy (SEM/EDX), Raman spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), and Electron Backscatter Diffraction (EBSD). The results unequivocally demonstrated the protective nature of the coating, significantly enhancing the alloy's durability as evidenced by corrosion and fatigue-corrosion tests. These findings underscore the substantial potential of Nb₂O₅ coatings in extending the service life of 2198-T8 aluminium alloy when subjected to aggressive environments, thereby providing invaluable data for aerospace engineering applications. |
