INFIUENCE OF TEMPERATURE AND SULFUR ION ON CARBON DIOXIDE CORROSION BEHAVIOR OF N80 STEEL
温度和硫离子对N80钢CO2腐蚀电化学行为影响

The joint effect of temperature and sulfur ion on the carbon dioxide corrosion behavior of N80 steel was investigated by electrochemical impedance spectra(EIS).The microstructure and composition of the corrosion scale was observed and analyzed by scanning electron microscopy(SEM) and energy despersive spectra(EDS).The results showed that temperature and sulfur ion have significant effect on the corrosion behavior of N80 steel.With the addition of sulfur ion,the sample surface was covered by a corrosion scal...
