Abstract:
<p align="justify"> Electrochemical measurements (steady-state current-voltage curves) were coupled with Mossbauer spectroscopy techniques to investigate the corrosion of carbon steel in diluted ammoniacal media. The corrosion current for carbon steel in diluted ammoniacal media was determined from galvanostatic measurements, through extrapolation of the Tafel segments at the corrosion potential. Mossbauer measurements were performed at room temperature in the transmission (TMS) and conversion electron spectroscopy (CEMS) using a conventional constant-accelerating spectrometer with a ⁵⁷Co-Rh source. The result of the corrosion is the layer appearance (nonstoichiometric iron oxide) on the sample surface. </p>
