The corrosion behavior of aluminum bronze under thin electrolyte layers (TELs) that contain artificialsea water has been investigated via Tafel polarization curve measurements, cathodic potentiodynamiccurve measurements, electrochemical impedance spectroscopy (EIS), X-ray diffraction (XRD),scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS). Tafel polarizationcurve showed that the corrosion rate increased with decreasing TEL thickness at early stage, which isin good agreement with cathodic potentiodynamic curves and EIS measurements. However, afterimmersion for long periods of time, the corrosion rate varied non-monotonically with TEL thickness,at 302 m02 m03 mulk solution. The morphologies and EDS results demonstrated thataluminum bronze suffered a dealuminification corrosion and that the corrosion occurred initially at theinterface between the matrix and the phase, before developing further within the phase.
