用旋转圆环圆盘电极筛选缓蚀剂方法的研究

Studying the Sieving Method for the Inhibitors by Means of the Rotating Ring-Disk Electrode

本文研究了用RRDE(旋转圆环圆盘电极)法测出的环电流与用失重法测出的相应的腐蚀速度之间的关系,发现二者的变化基本一致,据此认为可用RRDE法测定环电流代替失重法测定腐蚀速度,从而对缓蚀剂的优劣进行评价。

This paper shows the relations between the corrosion velocity by means of the method of loss in weight and the ring current by means of the RRDE, It is found that the change of them is identical no the whole. It is considered from this that the corrosion velocity by the method of Ioee in weight can be substituted by the ring current by the method of the RRDE so as to evaluate the inhibitors.
