Description

A kind of multi-function Hall cell system

technical field

The utility model relates to the field of electrodeposition devices and equipment, in particular to a multifunctional Hall cell system.

Background technique

Hall cell, also known as Hastelloy cell or Hull cell, is a necessary device for Hall cell test. The Hall cell is an indispensable tool for electrodeposition research due to its advantages of good test effect, simple operation, and less liquid consumption.

Nevertheless, existing Hall cell test setups still have limitations. The hallmark characteristics of the Hall cell are: high current density near the cathode and thick coating, low current density far away from the cathode and thin coating. Although this feature is conducive to the evaluation and analysis of electrodeposition effects under different current densities, such as hardness and morphology, it cannot scientifically evaluate the uniformity of thickness distribution and internal stress state of the electrodeposited layer. In addition, most of the existing Hall tanks do not have a temperature control system, so they cannot be tested according to the temperature required by production. In addition, most of them do not have a stirring device close to the production site, resulting in low reference value for the production site of the test results. In short, although the current Hall cell has a variety of functions, it still has shortcomings such as difficulty in simulating the real production site, and the analysis function indicators are not comprehensive enough. Therefore, it is urgent to develop a Hall cell system that not only has the functional characteristics of the conventional Hall cell, but also can simulate the actual production and evaluate more process effects.

Preferably, there are multiple liquid inlet holes in the Hall cell, the diameter of each liquid inlet hole is 2mm, the distance from the center of the circle to the cathode wall is 20mm, and the hole spacing is 10mm.

Preferably, there are multiple liquid inlet holes in the electrodeposition tank, the diameter of each liquid inlet hole is 2mm, the distance from the center of the circle to the cathode wall is 20mm, and the hole spacing is 10mm.

The working principle of the utility model is as follows. If it is necessary to carry out the Hall tank experiment, adjust the on-off channel of the two-position three-way valve, so that the electrolyte flows through the liquid inlet pipe and enters the Hall tank from the liquid inlet hole. At the same time, the electrolyte solution exceeding the specified volume of the standard Hall cell overflows into the regulating tank from the overflow port. After the electrolyte is heated in the regulating tank, it flows from the regulating tank. The liquid flows out of the outlet hole and enters the circulating filter system, then flows into the Hall tank, and so on. In addition, it is also possible to cut off the liquid inlet hole of the Hall tank and/or turn off the temperature control function in the adjustment tank according to the needs, so as to conduct Hall tank experiments such as static plating and room temperature electrodeposition.

A large amount of electrolyte overflows into the regulating tank from the overflow port. After being heated in the regulating tank, the electrolyte flows out from the liquid outlet hole of the regulating tank and enters the circulation filter system, then flows into the electrodeposition tank, and so on. In the experiment, since the cathode is in a suspended state, the stress state and size of the metal layer deposited on the cathode can be judged according to the bending direction of the cathode (whether facing the anode or facing away from the anode).

If it is necessary to carry out the Hall cell experiment and the conventional electrodeposition experiment at the same time, it is only necessary to enter the electrolyte into the Hall cell and the deposition cell at the same time, and then carry out the proposed experiment simultaneously and independently according to the experimental requirements.

The utility model has the advantages of:
