Technical Field
The invention relates to the technical field of metal corrosion, in particular to an electrolytic cell device for controlling the depth of an electrolyte layer on the surface of a metal and an adjusting method thereof.
Background
Corrosion of metals in electrolyte solutions is a complex redox process, where oxygen-absorbing corrosion plays an important role in the corrosion process. Oxygen in the air is dissolved into the electrolyte solution through the interface between the electrolyte and the air, and then reaches the metal surface through diffusion and oxygen absorption corrosion occurs. The more oxygen reaches the surface of the metal, the more severe the oxygen uptake corrosion of the metal occurs. The transmission of oxygen in the electrolyte solution is closely related to the depth of the electrolyte solution, and the deeper the depth of the electrolyte layer on the metal surface is, the more difficult the oxygen diffusion process reaches the metal surface, and the slower the oxygen absorption corrosion speed of the metal is.

The method for controlling the electrolyte depth of the metal surface by gradually evaporating the electrolyte has long time, the electrolyte depth of the metal surface cannot be accurately ensured, a certain amount of electrolyte is required to be poured into the electrolytic cell each time by pouring the electrolyte into the electrolytic cell and then measuring the electrolyte depth of the metal surface by using a measuring device, and then the electrolyte depth of the metal surface is measured by using complicated detecting equipment.
