Problems solved by technology

Ordinary dynamic tests can only use a fixed speed for simulation tests, and the efficiency is relatively low
The rotating disc electrode can carry out continuous electroplating tests at different linear speeds, and monitor the potential change curve through the electrochemical workstation. However, the test pieces obtained by this method are small, and it is impossible to conduct scanning electron microscope morphology analysis for different parts to investigate the plating layer.

Description

technical field [0001] The invention relates to an electroplating test device, in particular to a continuous electroplating test device for simulating different linear speeds of strip steel, belonging to the technical field of electroplating. Background technique [0002] The electroplating process is a complex electrochemical process. The quality of electroplating products is not only related to the formula of the plating solution, but also related to the surface condition of the plated parts, the flow of the plating solution, and the relative speed of the plating solution and the plated parts. Laboratory simulation electroplating mainly includes static simulation and dynamic simulation. In order to truly reflect the process operation status of electroplating, dynamic electroplating is often used for testing. Ordinary dynamic tests can only use a fixed speed for simulation tests, and the efficiency is relatively low. The rotating disc electrode can carry out continuous ele...
