The boundary layer is characterized by a concentration gradient of the oxidized ion. Diffusion of the reducing agent ion through the boundary layer controls the REDOX reaction.
边界层的特征在于被氧化离子的浓度梯度，还原剂离子的扩散通过边界层控制了氧化还原反应。
The redox reaction occurs at the surface of the substrate between a reducing agent ion and a plating ion and produces an oxidized ion.
