The propagation of localized corrosion on API 5L X65 carbon steel in hydrogenocarbonated solution containing chloride ions was monitored during long immersion times by electrochemical noise (EN) measurements ZRA mode. Monitoring from the EN amplitude is possible but interpreting potential and current transients after made difficult different processes (metastable or stable pits, crevices, produ...

To understand the behavior of corrosion films on X65 C-steel under CO2 conditions is paramount to identify formation and transformations products. This work presents chemical changes mechanical effects produced by pH flow through combination molecular techniques with imaging. Siderite, wustite magnetite were identified as products at neutral pH, which dissolved damaged low a 1m/s brine crystal ...
