在腐蚀过程的阴极反应是由电化学反应过程和传质过程混合控制的情况下,腐蚀金属电极的弱极化曲线方程式包含4个电化学动力学参数。迄今还没有一个方法可以同时测定这些动力学参数。本文证明,利用高斯—牛顿曲线拟合法直接对腐蚀金属电极的弱极化曲线拟合,可以解决这一问题。编制了一个BASIC语言的计算程序,并讨论了编制程序时应加以考虑的问题。 In the case of a cathodic reaction of the corrosion process controlled by the electrochemical reaction process and the mass transfer process, the weak polarization curve equation of the corrosion metal electrode contains four electrochemical kinetic parameters. So far there is no way to determine these kinetic parameters simultaneously. This paper proves that this problem can be solved by directly fitting the weak polarization curve of the corroding metal electrode by Gauss-Newton curve fitting method. A BASIC language calculation program was developed and the issues that should be considered in programming were discussed.
