Electrochemical studies on pitting corrosion on Cr13 steel exposed to CO2 and artificial brine with high chloride concentration
- Within the project COORAL (German acronym for 'CO2 purity for capture and storage') first studies on piping steels exposed to CO2 and artificial brine with high chloride concentration have been carried out. Corrosion behavior of martensitic Cr13 steel (1.4034) was investigated in a corrosive environment (artificial saline brine, T = 60 °C, CO2-flow rate 3 – 5 L/h, atmospheric pressure, exposure times from 1 h up to 14 days) using electrochemical and metallographic techniques. Different corrosion kinetics were observed as a function of exposure times and chloride concentration in the artificial brine. In CO2-saturated brine pitting corrosion was observed at free corrosion potential, whereas in the brine without addition of NaCl a stable passive layer built up. Predictions about corrosion mechanism are made and verified by means of surface analytical techniques.
