分枝状沉积层扩散限制腐蚀前沿动力学
Front dynamics during diffusion-limited corrosion of ramified electrodeposits
摘要：
本文报道了多孔铜团簇在含氯化铜的薄间隙电池中的扩散限制腐蚀实验。通过仔细比较的腐蚀前沿速度和浓度分布的相移干涉法与理论预测，它表明，这一过程是很好地描述了一个一维的平均场模型的通用反应A + B（静态）-> C（惰性），只有扩散反应物（氯化铜）和一个静态反应物（铜）反应产生一个惰性产品（氯化亚铜）。实验的解释是由数学分析的模型方程，它允许的反应顺序和迁移数的扩散物种被推断辅助。物理参数来解释令人惊讶的相关性的一维平均场模型，尽管复杂的（分形）结构的铜团簇。
英文摘要：
Experiments on the diffusion-limited corrosion of porous copper clusters in thin gap cells containing cupric chloride are reported. By carefully comparing corrosion front velocities and concentration profiles obtained by phase-shift interferometry with theoretical predictions, it is demonstrated that this process is well-described by a one-dimensional mean-field model for the generic reaction A + B (static) -> C (inert) with only diffusing reactant (cupric chloride) and one static reactant (copper) reacting to produce an inert product (cuprous chloride). The interpretation of the experiments is aided by a mathematical analysis of the model equations which allows the reaction-order and the transference number of the diffusing species to be inferred. Physical arguments are given to explain the surprising relevance of the one-dimensional mean-field model in spite of the complex (fractal) structure of the copper clusters.
