摘要：
A creative methodology of ultrasonic-electrochemical chloride extraction (UT) is proposed which is an improvement of the traditional electrochemical chloride extraction (ECE) through the assistant of ultrasonic wave and according experimental investigation on the viability of this method is carried out. The results indicated that the Cl- extraction efficiency of UT was approximately 19% higher than that of ECE, and the corrosion current density of UT group obtained through Linear Sweep Voltammetry was also the lowest which further demonstrates that ultrasonic wave had positive and obvious effect on halting the corrosion of Cl- on steels.
