Description

Technical Field

[0001] The utility model relates to the field of electrochemical deposition, in particular to a magnetic stirring auxiliary jet electrochemical deposition processing device. Background Art

[0002] Jet electrodeposition is a process in which the electroplating liquid is sprayed at high speed from the anode nozzle to the cathode workpiece surface under the action of an electric field to achieve deposition. It is widely used in the fields of microelectronics, chemical industry, and automobile industry due to its high localization and fast deposition rate. However, the pure metal coating prepared by jet electrodeposition is difficult to meet the increasingly complex working environment in terms of hardness and corrosion resistance. In order to solve these problems, scholars have introduced reinforcing phase nano-ceramic particles. However, due to the high electrochemical activity of nanoparticles, there are a large number of unsaturated bonds on the surface, so nanoparticles are easy to agglomerate in the electroplating solution. The uneven distribution of nanoparticles will lead to uneven coating thickness and even cracks, which not only reduces the bonding force between the coating and the substrate, but also greatly reduces the quality and performance of the coating. Therefore, a magnetic stirring assisted jet electrodeposition processing device with simple structure and convenient operation is proposed to effectively solve the above problems.
