恒电量法有许多独特的优点:测量时间很短,可在高阻介质中使用,能测得较多的参数,对电极表面状态干扰很小等,在金属腐蚀的研究测量领域中用途广泛。恒电量法用于缓蚀剂评价,国内外文献还极为少见。本文采用新的解析方法,通过线性区和弱极化区域的恒电量极化,求解出B=β_a·βē/2.3(β_a+βē)值、Rp值以及C_d值和I_((?)orr)值,以此来对缓蚀剂进行评价。并将其结果与失重法进行了比较。
Constant charge method has many unique advantages: the measurement time is very short, can be used in high resistivity media, can measure more parameters, the electrode surface state interference is very small, etc., in the field of metal corrosion research and measurement purposes. Constant electricity method for corrosion inhibitor evaluation, domestic and foreign literature is extremely rare. In this paper, we use the new analytical method to solve the B = β_a · βē / 2.3 (β_a + βē), Rp, C_d and I_ (?) Orr by the constant polarization of the linear region and the weakly polarized region. Value, in order to evaluate the corrosion inhibitor. The results were compared with the weight loss method.
