摘要
采用动电位扫描法研究了J55套管钢在25~140℃的模拟油田水中的极化行为,并用曲线拟合法求得了各温度下的腐蚀电化学参数.结果表明,随着温度的升高J55套管钢的极化行为和各种腐蚀电化学参数均产生了很大变化.
In simulated oil field aqueous solution,the polarization behaviors of J55 steel at different temperatures(25~140℃)were studied by means of potential scanning,and the corrosive electrochemical parameters(Icorr,βa,βc,IL)were calculated by the curves fitting method.The results showed that the polarization behaviors and electrochemical parameters of J55 steel were largely changed at different temperatures.
