本文对电结晶过程中成核的动力学基本方程即 Erdey-Gruz,Volmer 方程进行了初步讨论,并将过电位与电毛细现象相联系,通过 Lippman 方程的结合,推导出一个更能普遍应用于电结晶成核动力学的较广义的方程。考虑到电结晶过程中不同的控制因素,可以认为:当交换电流密度较大而表面扩散成为控制步骤时,即η_k≈η结晶,本文的方程可简化为 Erdey-Gruz,Volmer 方程;反之,若η_kη结晶,则 N=a·exp{-b′{σ_0-[(_(eq)-η_k)~2-_0~2]}~3}。本文的方程不仅具有更普遍的适用性,而且可以考虑作为发展新的电镀液检测方法的基础。
In this paper, the basic equations of kinetics of nucleation during electrocrystallization, namely the Erdey-Gruz and Volmer equations, are preliminarily discussed, and the overpotential is related to the electrocapillarity. By the combination of the Lippman equations, a more generalized The more generalized equation for nucleation kinetics of electrocrystallization. Considering the different control factors in the process of electrocrystallization, it can be considered that the equation in this paper can be simplified to the Erdey-Gruz and Volmer equation when the exchange current density is large and the surface diffusion becomes the controlling step, ie η_k≈η. On the contrary, if η_kη crystallizes, N = a · exp {-b ’{σ_0 - [(_ (eq) -η_k) ~ 2-_0 ~ 2]} ~ 3}. The equations in this paper not only have more general applicability, but also can be considered as the basis for developing new electroplating solution detection methods.
