Interrogating Iron Calcium Carbonate Corrosion Layer Properties Using Electrochemical Impedance Spectroscopy

Robert Jacklin, Richard C. Woollam, Joshua Owen, Danny Burkle, Richard Barker
... area of steel specimens immersed in solution. The selected CO2 charging procedure allowed for repeatable generation of a 5.5 bar pCO2 initial vapor phase for autoclave experiments conducted at 80°C. Corrosion layer formation was monitored using electrochemical techniques...

Iron Calcium Carbonate Formation in CO2 Environments – Effects of A/V Ratio in Autoclave Experiments

Robert Jacklin, Joshua Owen, Danny Burkle, Anne Neville, Richard C. Woollam, Richard Barker
... solution chemistry due to the corrosion process is critical when evaluating the effects of calcium on corrosion behavior. Autoclave experiments were conducted at 80°C and 5 barg with 3 brines containing 0, 1000 and 5000 mg/l of Ca2+. Iron flux into the brine was varied using high and low area...
