Description
technical field [0001] The invention relates to an electrodeposition device, which belongs to the technical field of special processing in manufacturing technology. Background technique [0002] Electrodeposition technology is the basis of metal electrolytic smelting, electroplating, and electroforming processes. In addition to traditional protection applications such as decoration, wear resistance, friction reduction, and corrosion protection, it is currently used in surface modification, electrical performance coatings, and optical performance coatings. And the development of new materials has become a very important modern processing technology and plays an important role. [0003] Electrodeposition technology is one of the most widely used technologies for preparing catalysts in industry. However, it is difficult to accurately control the distance between cathode and anode during the preparation process, and problems such as concentration polarization during the depositi...
