Advantages
- It brings a bright shiny finish that is visually appealing
- Reduces roughness by leveling micro-peaks and valleys
- Extends the fatigue life of metal parts by removing surface imperfections
Notes
- You cannot eliminate obvious processing marks after electropolishing
- Electropolishing is more expensive than mechanical polishing methods
Electropolishing Process
The workpiece is used as the anode and connected to the positive pole of the DC power supply. A conductive material resistant to electrolyte corrosion is used as the cathode and connected to the negative pole of the DC power supply.
The workpiece and the cathode material are immersed in the electrolyte (sulfuric acid and phosphoric acid as the main solution) at a certain distance. Under certain temperature, voltage and current density conditions, the tiny protrusions on the surface of the workpiece begin to dissolve and gradually become a smooth and bright surface.
