| description | This study investigates the metastable pitting corrosion behavior and passive film characteristics of metallurgically clad pipe (MCP) 825 within simulated oilfield produced water. Electrochemical testing and microstructural examination were employed to assess the corrosion behavior. The results revealed a narrowing of the passivation region and an increased frequency of metastable pitting nucleation. These phenomena are attributed to the enlarged grain size and the proliferation of precipitate phases within the MCP 825. X-ray photoelectron spectroscopy analysis unveiled a decreased fraction of Cr3+ and Fe3+ ox in the passive film. Additionally, an elevated concentration of vacancies and a rapid vacancy diffusion rate were observed, leading to diminished defect performance as indicated by Mott-Schottky (M − S) and electrochemical impedance spectroscopy (EIS) results. |
