In situ early-stage CO2 corrosion scale study with 2D synchrotron SAXS-WAXS
Source abstract
Abstract
In this study we have investigated the nucleation mechanism of ‘sweet’, CO 2 corrosion scale in situ using synchrotron scattering under industrially relevant conditions (CO 2 saturated brine, ultra-low oxygen (8-32 ppb), 80 o C, pH 6.8, open-circuit-potential (OCP)). Simultaneous small and wide-angle X-Ray Scattering (SAXS-WAXS) measurement allows the phase and state of the nucleating corrosion scale to be characterised as a function of both immersion time and location with respect to the metal/solution interface. The results indicate that a precursor amorphous phase is formed prior to the emergence of a crystalline iron carbonate scale.
