The corrosion behavior of carbon steel in CO2-saturated NaCl crevice solution containing acetic acid
The corrosion behavior of X52 carbon steel electrodes in CO2-saturated NaCl crevice solution containing HAc was investigated by electrochemical measurements. Chemical environment measurements by Cl− and pH microprobes show an enrichment of Cl− i[...]
