Description

technical field [0001] The invention relates to an electrochemical processing technology, and relates to an ultrasonic-assisted supercritical electrodeposition device. Background technique [0002] Electrodeposition refers to the process in which metal or alloy or metal compound is deposited on the electrode surface from its compound aqueous solution, non-aqueous solution or molten salt under the action of an electric field, usually accompanied by electron gain and loss. Ordinary electrodeposition technology often has shortcomings such as uneven surface, pinholes, pitting, and excessive internal stress of the electrodeposition layer. [0003] Generally, the distance between the two pole plates of the electrodeposition fixture is fixed, and the distance between the pole plates cannot be changed. The jig is also made of metal. In the non-deposition area, the surface of the jig must be covered with insulating glue for electric field shielding before electrodeposition can be pe...

AI Technical Summary

Problems solved by technology

Generally, the connection between the pole plate and the power supply on the fixture is not very firm, and it will become loose during the stirring process, which will affect the coating effect

The fixing of the electrode plate is also cumbersome; and during the electrodeposition process, it is necessary to cover the non-deposition area on the fixture with insulating glue for electric field shielding, which will inevitably bring a lot of tedious pre-treatment operations

[0004] At present, in the technical field of electrodeposition, ultrasonic electrodeposition technology can be gradually introduced. For example, Chinese patent CN103255452A discloses a metal electrodeposition device, including a liquid storage tank for containing electrolyte and a The power supply corresponding to the cathode and anode in the center, the ultrasonic power supply, the ultrasonic auxiliary spraying device supported by the bracket, the three-coordinate numerical control platform, the three-coordinate numerical control platform includes the action actuator, the bracket and the computer; The peristaltic pump that provides the injection pressure and the control valve that controls the flow of the electrolyte; the liquid storage tank is equipped with a temperature controller to maintain the temperature of the electrolyte; there is an electrolyte nozzle at the bottom of the ultrasonic assisted injection device; but the above method does not solve the ultrasonic problem. The problem of cumbersome operation of electrodeposition
