本文提出了一个钝化金属电极系统恒电位阶跃条件下的线性模型,并据此模型,分析了钝化体系恒电位阶跃条件下的暂态响应过程,给出了一套解析反映钝化膜的生长与溶解性质的电化学参数的方法。该方法比交流阻抗能更加简便快速地测得同样的电化学参数。
In this paper, a linear model of passivation metal electrode system under potentiostatic step condition is proposed. Based on this model, the transient response process under constant potential step of passivation system is analyzed. Membrane growth and dissolution properties of electrochemical parameters of the method. This method can measure the same electrochemical parameters more easily and quickly than AC impedance.
