Modelling of coating thickness distribution on the edges of a moving cathode during electrogalvanizing
Electrogalvanizing is a widespread practice used to prevent steel corrosion. A mathematical model was developed to simulate the plating process and to predict the zinc coating thickness distribution at the cathode surface for different operating conditions. The model considers ternary current distri...

Electrogalvanizing is a widespread practice used to prevent steel corrosion. A mathematical model was developed to simulate the plating process and to predict the zinc coating thickness distribution at the cathode surface for different operating conditions.

Experiments were carried out to validate the model using an experimental device which reproduces the fluid dynamic and electrochemical conditions of the edges of a steel strip in an industrial electroplating line, the rotating washer electrode.
