Simulation analysis of electroplating zinc based on COMSOL

Abstract

There are many uncertain factors in the test process of electroplating zinc. The establishment of control standards in the research process can reduce the workload and shorten the test cycle. Based on the electrochemical module developed by COMSOL multi-physics software, this study uses the computer ‘s powerful computing power and the existing perfect theoretical system to simulate the experiment. The results show that the potential at the anode plate is higher, the potential at the cathode plate is lower, and the potential distribution in the middle area of the two plates is relatively uniform. When the plating time is 10 min, the outer surface of the galvanized part is basically coated with a relatively uniform zinc coating, which is about 2μm. Due to the large local current density in each edge area of the sample, the plating layer is relatively thick, but the difference is not large.
