  To understand the behavior of corrosion films on X65 C-steel under CO2
conditions is paramount to identify the formation and transformations of
corrosion products. This work presents the chemical changes and mechanical
effects produced by pH and flow on corrosion films through the combination of
molecular techniques with imaging. Siderite, wustite and magnetite were
identified as corrosion products at neutral pH, which dissolved and mechanical
damaged at low pH by a 1m/s brine flow with a crystal size reduction of ~80%.
In contrast, at pH 7 and 1m/s flow facilitated the removal of entire crystals
from the film.
