Description

Technical Field

[0001] The invention relates to the technical field of electrochemical polishing, and in particular to a bracket polishing device in electrochemical polishing. Background Art

[0002] Electrochemical polishing is also called electrolytic polishing. Electrolytic polishing uses the workpiece as the anode and the insoluble metal as the cathode. The two electrodes are immersed in the electrolytic cell at the same time and direct current is passed to produce selective anodic dissolution, thereby achieving the effect of increasing the brightness of the workpiece surface. The advantages of electrolytic polishing are: 1. The color inside and outside are consistent, the gloss is long-lasting, and the concave areas that cannot be polished by mechanical polishing can also be leveled; 2. High production efficiency and low cost; 3. Increase the corrosion resistance of the workpiece surface; The principle of electrolytic polishing is that the metal ions detached from the workpiece and the phosphoric acid in the polishing liquid form a phosphate film that is adsorbed on the surface of the workpiece. This mucous film is thinner at the protrusions and thicker at the concave areas. It dissolves faster due to the high current density at the protrusions. As the mucous film flows, the concave and convex areas change continuously, and the rough surface is gradually leveled.
