Reaction Steps for Metal Electrodeposition - Phase Generation

       phase generation

 

     The new phase generation step is the step in which the reaction product generates a new phase (eg, the formation of a crystalline structure or bubbles). Fischer first introduced the term "electrocrystallization" to summarize the process of forming the crystalline structure on the electrode by particles in solution under the action of an electric field.

 

     The electric current is established between the electrodes through the plating solution, and the plated metal ions are continuously transported from the body of the solution to the electrode surface area by mass transfer. The electrode surface structure of the phase forms new phases, and these are the processes experienced by metal electrodeposition on the cathode.

 

     Among various electrode processes, any one electrode process includes mass transfer steps, electrochemical steps and new phase generation steps, some electrode processes also include conversion before and after electrochemical steps or one of them, some in addition to continuous Parallel reactions may also occur in addition to the reactions.
