摘　　要：通过测量30℃下的稳态极化曲线和不同温度下的腐蚀速率,研究了20A碳钢在4% EDTA溶液中的腐蚀行为.实验结果表明该腐蚀过程由析氢反应和氧还原反应共同控制,并且在30～150℃的范围内温度的升高未改变腐蚀反应历程.The corrosion behavior of 20A carbon steel in 4M EDTA solution was studied by measuring steady-state polarization curves at 30℃ and corrosion rates at various temperatures. The results revealed that the corrosion process was controlled by both hydrogen evolution and oxygen reduction reactions in the temperature range from 30 to 150℃.
