The coating degraded via pitting, generalized, and crevice corrosion, as evidenced by scanning electron microscopy-energy-dispersive x-ray analysis (SEM-EDX) investigation. The corrosion mechanism was investigated in situ by means of electrochemical impedance spectroscopy (EIS), and ex situ by x-ray photoelectron spectroscopy (XPS). These combined results demonstrate that the key point of the corrosion failure is the removal of the passive In-Sn oxides. 2 Corrosion 68 ARTICULO ddc 186945 186945 0 0 0 0 254764 BAAB BAAB 2026-03-06 200059051 0 200059051 2026-03-06 00:15:25 2026-03-06 ARTICULO
