[中文文摘]本文根据电位控制脉冲电流法来设计采用线性极化原理的腐蚀速率仪,可克服目前腐蚀速率仅,尤其是超低速腐蚀速率仪研制中普遍存在的双电层充电电流,溶液欧姆电位降及自腐蚀电位漂移等造成的困难。[英文文摘]On the basis of the potential control led-pulse current method, Corrosion Speedometer was designed on the linear polarization principle. The difficulties generally encountered in the investigation of corrosion speedometer, especially the speedometer for corrosion with ultra-low speed, are due to the double layer charging current, the olirnic potential drop of solution and the self-corrosion Potential drift. All these difficulties are overcome in this apparatus
